This work aimed to identify the bioactive constituents of Ducrosia anethifolia Boiss eaves through cold methanolic extract. The GC–MS study of cold methanolic extract showed the presence of various pharmaceutically important bioactive compounds with unique peaks at specified retention time. The significant compounds are a-linoleic acid, a-sitosterol, n-hexadecanoic acid, palmitic acid b-monoglyceride, 2-methoxy-4-vinylphenol and benzoic acid, methyl ester. The FT-IR studyshowed them fingerprint region at 3326.80, 2943.53, 2831.74, 1450, 1110.67 and 1020.80 cm
1. The FT-IR study suggested the presence of glycosides, flavonoids, tannins, steroids, saponins, fatty acids and squalene. Oral administration of Ducrosia anethifolia Boiss leaves powder (DLP) (100 mg/kg body weight) was successfully reduced the blood sugar level after 14 d treatment in STZ (50 mg/kg bodyweight) induced diabetic rats significantly from 327.93 ± 24.5 to 171 0.03 ± 3.78 mg/dL. Furthermore, DLP (400 mg/kg body weight) was showed 74 ± 1.9 % inhibition of ulcer. The results of this study showed that DLP has both anti-diabetic and anti-ulcer characteristics when tested in vivo.
