The fresh odor of raw myrrh and its hexane extract depended on the amount of （E）-13-ocimene. Myrrh was extracted with hexane to avoid inducing changes in the constituents and odor. The main constituent, （E）-L3-ocimene （group A; low boiling point）, and the other constituents （group B; high boiling point） of the hexane extract were separated by bulb-to-bulb distillation. The constituents of groups A and B were analyzed over time by nuclear magnetic resonance analysis and the odors were evaluated. Myrrh＇s odor depended on both the amount of thermally unstable （E）-[3-ocimene, which contributed to the fresh odor, and the constituents of group B （thermally stable）, which contributed to the myrrh-like odor. Six compounds （c^-santalene, （Z）-a-bisabolene, c^-bergamotene, （E）-ct-santalal, c^-photosantalol and campherenol） were isolated from group B. No individual group B component had a myrrh-like odor, although the combined odor of group B was myrrh like. The authors demonstrated that the aroma profile of myrrh depends on the thermal instability of （E）-^-ocimene and a combination of six thermally stable terpenes with similar molecular structures.展开更多

This study was conducted to evaluate the effect of the new compound (Commiphora molmol(Myrrh)), as agent a natural product extracted from the roots of Zingiber officinal, on Giardia lamblia infection as anti-protozoal and to study the parasitological and Histopathological impact of this treatment on the duodenal mucosa of infected hamsters. Fifty hamsters were divided into five groups: Group (A): normal control. Group (B): Giardia lamblia infected and untreated hamsters served as control. Group (C): infected with Giardia lamblia and treated with metronidazole in dose (120 μg/kg body weight twice daily for 7 successive days). Group (D) Giardia lamblia infected and orally treated with Myrrh (500 mg/Kg for 1 week). Group (E): Giardia lamblia infected and orally treated with combination 1/3 dose of (120 μg/kg body weight) metronidazole and Myrrh (250 mg/Kg) for 1 week). After 2 weeks of the treatment, hamsters were sacrificed. The highest percentages of reduction in the number of Giardia lamblia cysts and trophozoites were in the group receiving combined metronidazole and myrrh. Histopathological examination revealed complete healing of intestinal mucosa after the combined treatment, while partial healing of the lining epithelium of the intestine was noticed after metronidazole and either myrrh plant treatment.展开更多

Myrrh is commercially available as a brown powder. The objective was to determine the effect of myrrh on the color (L*, a*, b*, C*, h*) and viscosity of yogurt over refrigerated storage. Myrrh dispersion was prepared and incorporated at a 1% v/v level into yogurt. A control with no myrrh was also prepared. Three replications were conducted. At a small usage level of 1% v/v, myrrh influenced the color attributes L*, a* and h* but did not influence the viscosity of the plain yogurts.展开更多

The Antiulcer Activities effects of myrrh or Commiphora molmol extract (CME) were assessed in rats. In this experiment, thirty rats were divided into 6 groups as follows: G1) normal control (vehicle);G2) received aspirin without any treatment;G3) pretreated with Omeprazole (antiulcer drug) and groups (4), (5) and (6) were pretreated with CME at 125, 250 and 500 mg/kg b.wt, respective-ly for 2 weeks. At the end of experiment the volume, pH and total acidity of gastric juices;mucus content and ulcer lengths were measured and protection percentages were calculated. Gross and histopathological examinations of stomachs were also performed. CME induced an antiulcer effect manifested by decreased volume and total acidity of gastric juice and increased mucus content and percentages of protec-tion from ulcer as well as partial amelioration of gross and histopathological lesions seen in stomach of ulcerated rats. In conclusion, the results denote that Commiphora molmol extract possess antiulcer effects in rats. These results affirm the traditional use of Myrrh extract for the treatment of gastric ulcer.展开更多
