Twenty-four adult white Swiss mice were used in this study. Experimental animals were divided into four groups, with six mice in each group. For mating to occur, three females and a male were placed in the cage. We prepared three sublethal concentrations of Curcuma longa and applied them to the experimental groups except the control group: 10 mg/kg, 50 mg/kg, and 100 mg/kg. From 7–14 days of gestation, we gave the pregnant mice 0.1 ml per 10 g of body weight. After 18 days of gestation, we extracted the embryo to study the effect of the alcoholic extract, the weights and lengths of the embryos, the embryo malformation, as well as the weight of mice before and after the experiment. This study shows a significant (P<0.01) decrease in the body weight of mice treated with three concentrations (10, 50, and 100) mg/kg compared with a control group, but there is no significant difference in the lengths and weights of mouse embryos. Concentrations of 50 mg/kg and 100 mg/kg show many malformations induced in the mice compared with embryos of the control group, including cleft lips, hemorrhage, and Micromelia, as well as absorbed embryos at 50 mg/kg and 100 mg/kg. This study concluded that an alcoholic extract of (Curcuma longa) has teratogenic effects on the embryos of mice. Keywords: Curcuma longa, embryonic malformation, Micromelia, Teratogenic effects. 1. Introduction As medical tools and alternative therapeutic, those medical plants are excessively used for the treatment and protection of many diseases [1]. Medical plants have natural products that are used in pharmaceutical preparations; these compounds may be pure or extracted [2].

Curcuma longa is a perennial plant with wide leaves and yellow flowers (4). Curcuma longa is also known as ''Kurkum'' in Arabic, "Haldi" in India, and ''turmeric'' worldwide [5]. Curcuma longa is also one of the important compounds in curries that give them their yellow pigment in India, Malaysia, China, and Thailand (6). The yellow pigment and healing properties of turmeric are related to compounds in it [7]. The most commonly used part of these plants is the rhizome. The volatile oil and nonvolatile curcuminoids are the main active compounds in the rhizomes [8]. The largest country that produces turmeric is India, which supplies more than 90% of the world’s demand [9]. According to the World Health Organization (WHO), about 80% of people in developed countries use this tradition [10]. The major component in Curcuma longa is curcumin, which is responsible for biological activity [11]. Curcumin is the most important polyphenol compound that is present in and isolated from the rhizome [12]. Curcumin also has various pharmacological activities, such as antioxidant, anti- inflammatory, antifungal, and antibacterial [13]. Curcumin is the main curcuminoid found in turmeric. Desmethoxycurcumin and bis-desmethoxycurcumin are other curcuminoids [14]. The aim of this study is to determine the effect of an alcohol extract of Curcuma longa on mice's embryonic development during the gastation period. 2. Materials and Methods Twenty four mice with ages from 8 to 6 weeks and weights from 29-22 grams were used. We obtained the animals from the Animals House of Biotechnology Research Center at Al-Nahrain University. The animals (females) were divided into four groups (6 mice per group), and we placed three females and one male in each cage. In the early morning, they observed the vaginal plug being placed after mating; this day was considered the zero day of pregnancy, followed by the day considered the first day of gastritio [15].We selected three sub lethal concentrations of Curcuma longa, 10mg/kg, 50mg/ 100 mg/kg the LD50 of Curcma Longa is 2000 mg/kg [16]. We used the gavage tube for oral administration. Between 7-14 days of gastation, the mice were orally administered 0.1 ml per 20 units of weight every day. The mice in the control group were also administered 0.1 ml per 20 units of weight of distilled water. In this study, we took the weights of females before and after the end of the experiment. Pregnant mice were dissected after 18 days of pregnancy; the fetuses were extracted from the uterus to study the fetal malformation, and lengths and weights were recorded. We used Curcuma longa powder and alcohol methanol in ratio of 1:10 (weight to size) at 60-80 °C about 6-8 hours by soxhlet extactor, then used filter paper to extract the liquid and left it to dry out of sun. 3. Results and Discussion Table 1 shows that there is a significant (p >0.01) decrease in body weight in pregnant mice that were treated with 10mg/kg, 50 mg/kg and 100 mg/kg concentrations of alcoholic extract of Curcuma longa.

This agrees with a previous study that showed the weight of pregnant rats after being administered for 6–15 days of gestation decreased the weight gain of female rats, which was comparable to gabapentin. Gabapentin (50 mg/kg bw) and C. Mangga extract (1000 mg/kg bw) also caused resorption. Resorption might arise due to disruption in morphological development, which causes malformations and death [17]. Table 2.

The size and weight of the fetus indicate nutritional and developmental support through the pregnancy [18]. Previous studies show the mean litter size of the fetus was 6.80 at 6–15 days of pregnancy. These results indicate that curcuma had no effect on the size of embryos compared to normal (p >0.005) [20]. In Figure 1, the control fetus at 18 days of gestation has eyes, an ear pinna, a mouth, a trunk, and a tail. Figer 2 shows the difference between the control fetus and the treated fetus with 10 kg/mg of Curcuma longa which has micromelia (M.m.). Table 3.

The organogenesis period in pregnancy is a critical period. In this period, cell differentiation occurs to build tissue and organs. Therefore, malformations occur in this period if exposed to toxic materials [19]. Saponins, steroids, terpenoids, and flavonoids are second-metabolites present in curcuma rhizomes. These compounds are active, have pharmacological activities, and might also be toxic in high concentrations. Previous studies showed a flavonoid derivative drug (hydroxyethylrutoside) caused congenital abnormality syndrome [21]. In addition, reproductive toxicity effects appeared in the female mice because of saponin presence [19]. In a previous study, curcumin also showed the ability to inhibit chondrogenesis by stimulating apoptosis and also impair bone development by reducing actin cytoskeleton reorganization [22]. Distruption in morphology development that leads to malformation and death may raise resorption [19]. 4.Conclusions This study concluded that an alcoholic extract of (Curcuma longa) has teratogenic effects on the embryos of mice.
