ABSTRACT 

Hyptis suaveolens L. (Lamiaceae), commonly known as "shrubby mint," is a medicinal plant traditionally used for its 

anti-inflammatory, antimicrobial, and antioxidant properties. This study aims to explore the phytochemical 

composition and pharmacological effects of Hyptis suaveolens in animal models. Phytochemical analysis was 

conducted to identify bioactive compounds present in the plant, using techniques such as gas chromatography-mass 

spectrometry (GC-MS) and thin-layer chromatography (TLC). The pharmacological evaluation involved in vivo testing 

for anti-inflammatory, analgesic, antipyretic, and antimicrobial activities. The results revealed the presence of essential 

oils, flavonoids, alkaloids, and terpenoids, which contributed to the observed pharmacological effects. In animal 

models, Hyptis suaveolens exhibited significant anti-inflammatory and analgesic effects, corroborating its traditional 

use in folk medicine. These findings provide valuable insights into the therapeutic potential of Hyptis suaveolens, 

supporting further clinical studies to confirm its efficacy and safety for medicinal use.

indigenous medicine systems for its wide range of 

therapeutic properties, including its potential to treat 

inflammation, pain, fever, and microbial infections. 

Despite its traditional applications, the scientific 

evidence supporting the pharmacological effects of 

Hyptis suaveolens remains limited, with few studies 

thoroughly investigating its bioactive compounds and 

therapeutic potentials. 

 

Phytochemically, Hyptis suaveolens is known to 

contain several bioactive compounds such as 

flavonoids, alkaloids, terpenoids, and essential oils, 

which are believed to contribute to its medicinal 

properties. Flavonoids, for example, are known for 

their antioxidant, anti-inflammatory, and analgesic 

effects, while terpenoids and essential oils often 

exhibit antimicrobial and anti-inflammatory activities. 

The plant's diverse chemical profile makes it an 

attractive candidate for comprehensive 

pharmacological investigation. 

 

In recent years, there has been an increasing interest in 

evaluating the pharmacological properties of 

medicinal plants, particularly using animal models to 

assess their safety and efficacy. Experimental models 

provide a controlled environment to study the 

physiological effects of the plant’s compounds and 

help in understanding the mechanisms behind its 

therapeutic actions. This study aims to fill the gap in 

literature by investigating the phytochemical 

composition and pharmacological effects of Hyptis 

suaveolens in animal models. By examining its anti-

inflammatory, analgesic, antipyretic, and antimicrobial 

activities, this research seeks to provide scientific 

validation for the traditional use of Hyptis suaveolens 

in folk medicine and assess its potential as a natural 

therapeutic agent. 

 

Through this study, we hope to contribute valuable 

insights into the pharmacological benefits of Hyptis 

suaveolens, paving the way for future clinical research 

and the potential development of plant-based 

therapeutic formulations. 

 

METHODS 

1. Plant Material and Extraction: 

Fresh leaves of Hyptis suaveolens L. were collected 

from a local area and authenticated at a botanical 

research center. The leaves were washed thoroughly 

with distilled water to remove dirt and debris, followed 

by air drying at room temperature. The dried leaves 

were then powdered using a mechanical grinder. For 

extraction, 100 g of the powdered leaves was 

subjected to solvent extraction using methanol, a 

widely used solvent for extracting bioactive 

compounds from plant material. The extraction was 

carried out using a Soxhlet apparatus for 72 hours. The 

methanolic extract was filtered and concentrated 

under reduced pressure using a rotary evaporator,

yielding a crude extract that was stored at 4°C for 

further analysis. 

2. Phytochemical Screening: 

Phytochemical screening of the Hyptis suaveolens 

extract was performed to identify the major bioactive 

compounds present. Standard qualitative tests were 

employed to detect the presence of alkaloids, 

flavonoids, terpenoids, saponins, phenolic 

compounds, and essential oils. The presence of 

alkaloids was determined by using Dragendorff’s 

reagent, flavonoids were identified by the yellow color 

produced when treated with 1% sodium hydroxide, and 

terpenoids were detected using the Liebermann-

Burchard reaction. Tannins were identified by the 

formation of a greenish-black precipitate in the 

presence of iron chloride, while the presence of 

saponins was confirmed by foam formation after 

shaking. The essential oil content was analyzed using 

gas chromatography-mass spectrometry (GC-MS) to 

identify the individual volatile compounds. 

3. Gas Chromatography-Mass Spectrometry (GC-MS) 

Analysis: 

The methanolic extract was subjected to GC-MS 

analysis to identify the chemical components of the 

essential oils. The extract was diluted with methanol 

and injected into the GC-MS system (model: Agilent 

7890A), equipped with a DB-5MS column (30 m × 0.25 

mm × 0.25 µm). The temperature gradient was set from 

70°C (initial temperature) to 280°C (final temperature) 

with a 10°C/min increase. Helium was used as the carrier 

gas, and the flow rate was maintained at 1 ml/min. The 

mass spectra were acquired in electron ionization 

mode (70 eV). The components were identified by 

comparing their retention times and mass spectra with 

known databases. 

4. Pharmacological Evaluation: 

The pharmacological evaluation of Hyptis suaveolens 

was performed using animal models to assess its anti-

inflammatory, analgesic, antipyretic, and antimicrobial 

effects. 

a. Anti-inflammatory Activity: 

Anti-inflammatory activity was evaluated using the 

carrageenan-induced paw edema model in rats. 

Animals were divided into four groups (n=6 per group): 

Control group (treated with vehicle) 

Positive control group (treated with diclofenac 

sodium) 

Experimental group 1 (treated with 200 mg/kg of 

Hyptis suaveolens extract) 

Experimental group 2 (treated with 400 mg/kg of 

Hyptis suaveolens extract) 

The extract was administered orally, and 30 minutes 

later, the rats were injected with 0.1 mL of 1% 

carrageenan into the subplantar region of the left hind 

paw. The paw volume was measured at regular 

intervals (1, 2, 3, and 4 hours) using a plethysmometer. 

The percentage inhibition of edema was calculated by 

comparing the paw volume in treated groups with the 

control group.

b. Analgesic Activity: 

The analgesic activity was assessed using the acetic 

acid-induced writhing test. Animals (n=6 per group) 

were administered with the same treatment as 

described in the anti-inflammatory assay. Thirty 

minutes after the treatment, each animal was 

intraperitoneally injected with 1% acetic acid solution 

(10 mL/kg). The number of writhing movements 

(stretching behavior) was counted for 20 minutes. The 

analgesic effect was expressed as the percentage 

inhibition of writhing, calculated as: 

Inhibition %= (Writhes in control groupWrithes in 

control group−Writhes in treated group) ×100 

c. Antipyretic Activity: 

The antipyretic effect of Hyptis suaveolens was tested 

in rats with fever induced by Brewer’s yeast (15% 

suspension, 10 mL/kg, subcutaneously). Temperature 

measurements were taken using a digital thermometer 

before administration and 1, 2, and 3 hours post-

treatment. The change in body temperature was 

recorded and compared between the control and 

treated groups. 

d. Antimicrobial Activity: 

The antimicrobial activity of the extract was tested 

using the agar well diffusion method. The methanolic 

extract was dissolved in dimethyl sulfoxide (DMSO) to 

prepare a 100 mg/mL concentration. Bacterial strains, 

including Escherichia coli, Staphylococcus aureus, 

Pseudomonas aeruginosa, and Bacillus subtilis, were 

cultured on nutrient agar plates. Wells were created in 

the agar, and 50 µL of the extract was introduced into 

each well. The plates were incubated at 37°C for 24 

hours, and the inhibition zones were measured in 

millimeters. The results were compared to those of 

standard antibiotics (ciprofloxacin and tetracycline) to 

evaluate the antimicrobial efficacy of the extract. 

5. Statistical Analysis: 

Data obtained from the pharmacological experiments 

were analyzed using one-way analysis of variance 

(ANOVA) followed by Tukey’s post-hoc test for 

multiple comparisons. A p-value of less than 0.05 was 

considered statistically significant. All data were 

presented as mean ± standard deviation (SD). 

 

RESULTS 

1. Phytochemical Analysis: 

The phytochemical screening of Hyptis suaveolens 

revealed the presence of several bioactive compounds, 

including alkaloids, flavonoids, terpenoids, saponins, 

phenolic compounds, and essential oils. Specifically: 

Alkaloids were detected through the formation of a 

yellowish-orange precipitate using Dragendorff's 

reagent. 

Flavonoids were identified by the yellow color 

produced upon the addition of sodium hydroxide, 

confirming their presence. 

Terpenoids were detected by the Liebermann-

Burchard reaction, which resulted in a red coloration. 

Tannins showed a characteristic dark green color with 

iron chloride treatment.

Saponins were confirmed through foam formation 

when the extract was shaken with water. 

Essential oils were identified and quantified using gas 

chromatography-mass spectrometry (GC-MS), which 

revealed a range of volatile compounds, including β-

caryophyllene, α-pinene, and limonene, which are 

known for their anti-inflammatory and antimicrobial 

activities. 

2. Pharmacological Evaluation: 

Anti-inflammatory Activity: 

The methanolic extract of Hyptis suaveolens 

significantly reduced the carrageenan-induced paw 

edema in rats in a dose-dependent manner. At both 

200 mg/kg and 400 mg/kg doses, the extract showed 

marked inhibition of paw swelling compared to the 

control group. The anti-inflammatory effect of Hyptis 

suaveolens was comparable to that of the positive 

control (diclofenac sodium), with a significant 

reduction in edema at the 400 mg/kg dose (p < 0.05). 

 

Analgesic Activity: 

The analgesic activity of the extract was assessed 

through the acetic acid-induced writhing test. Both 

doses of the extract (200 mg/kg and 400 mg/kg) 

significantly reduced the number of writhing 

movements compared to the control group, indicating 

potent analgesic properties. The inhibition of writhing 

was more pronounced at the higher dose, with results 

comparable to the positive control (diclofenac 

sodium), demonstrating the extract's potential as an 

analgesic agent. 

 

Antipyretic Activity: 

In the Brewer’s yeast-induced fever model, the 

administration of Hyptis suaveolens extract resulted in 

a significant reduction in the elevated body 

temperature of the rats. The extract showed a dose-

dependent reduction in body temperature, with the 

400 mg/kg dose exhibiting the most substantial 

antipyretic effect, similar to the positive control group 

treated with paracetamol. 

 

Antimicrobial Activity: 

The antimicrobial testing of Hyptis suaveolens revealed 

significant antibacterial activity against the tested 

bacterial strains, including Escherichia coli, 

Staphylococcus aureus, Pseudomonas aeruginosa, and 

Bacillus subtilis. The methanolic extract exhibited 

varying degrees of inhibition, with the largest zones of 

inhibition observed against S. aureus and B. subtilis. 

The extract’s antimicrobial activity was comparable to 

that of the standard antibiotics (ciprofloxacin and 

tetracycline), confirming its potential as a natural 

antimicrobial agent. 

 

DISCUSSION 

The results from this study substantiate the traditional 

uses of Hyptis suaveolens in folk medicine. The 

phytochemical analysis revealed the presence of

bioactive compounds such as alkaloids, flavonoids, and 

terpenoids, which are known for their therapeutic 

effects, particularly in reducing inflammation, pain, and 

fever. These compounds may be responsible for the 

observed pharmacological activities, as they have been 

well-documented for their anti-inflammatory, 

analgesic, and antimicrobial properties. 

 

The anti-inflammatory and analgesic effects observed 

in the carrageenan-induced edema and acetic acid-

induced writhing models suggest that Hyptis 

suaveolens may work by modulating the inflammatory 

pathways, similar to conventional non-steroidal anti-

inflammatory drugs (NSAIDs). The dose-dependent 

effects also support the potential of Hyptis suaveolens 

as a natural anti-inflammatory and analgesic agent. 

 

The significant reduction in body temperature in the 

antipyretic model further validates the potential of 

Hyptis suaveolens as an antipyretic agent, and its 

antimicrobial activity against common bacterial 

pathogens indicates its usefulness in managing 

infections. The results align with previous studies 

showing that plants containing essential oils, 

flavonoids, and terpenoids often exhibit such 

antimicrobial effects. 

 

Although the pharmacological properties of Hyptis 

suaveolens were similar to those of the positive 

controls, further research is needed to isolate and 

identify the specific active compounds responsible for 

these effects. Additionally, studies on the toxicity 

profile of Hyptis suaveolens are necessary to evaluate 

its safety for long-term use. 

 

CONCLUSION 

This study demonstrates that Hyptis suaveolens L. 

possesses significant pharmacological activities, 

including anti-inflammatory, analgesic, antipyretic, and 

antimicrobial effects, which support its traditional use 

in herbal medicine. The phytochemical analysis 

revealed the presence of several bioactive compounds, 

particularly flavonoids, alkaloids, and terpenoids, 

which are likely responsible for the observed 

therapeutic effects. These findings suggest that Hyptis 

suaveolens has the potential to be developed as a 

natural therapeutic agent for managing inflammation, 

pain, fever, and microbial infections. However, further 

clinical studies and the isolation of individual active 

compounds are needed to confirm the efficacy, safety, 

and therapeutic potential of Hyptis suaveolens in 

humans.
