10.22376/ijpbs.2019.10.1.p1-12 Volume 6 Issue 1 2015 (January - March) Cloves ( lessThan i greaterThan Syzygium aromaticum lessThan /i greaterThan ) are the aromatic dried flower buds of a tree in the Myrtaceae family and Cinnamon ( lessThan i greaterThan Cinnamomum zeylanicum lessThan /i greaterThan ) bark are common Indian spices with enormous medicinal value. This study investigates lessThan i greaterThan in lessThan /i greaterThan lessThan i greaterThan vitro lessThan /i greaterThan anthelmintic activity of aqueous extracts of lessThan i greaterThan S. aromaticum lessThan /i greaterThan (floral buds) and lessThan i greaterThan C lessThan /i greaterThan . lessThan i greaterThan zeylanicum lessThan /i greaterThan (bark). Phytochemical analysis of the extracts of lessThan i greaterThan S. aromaticum lessThan /i greaterThan and lessThan i greaterThan C lessThan /i greaterThan . lessThan i greaterThan zeylanicum lessThan /i greaterThan revealed the presence of alkaloids, tannins, phenolics, phlobatannins, cardiac glycosides, anthraquinone glycosides, hydroxyl anthraquinones, flavonoids and terpenoids. Aqueous extracts of lessThan i greaterThan S. aromaticum lessThan /i greaterThan and lessThan i greaterThan C.zeylanicum lessThan /i greaterThan were evaluated for anthelmintic activity against Indian earthworm lessThan i greaterThan Pheritima posthuma lessThan /i greaterThan . Albendazole (10 and 20 mg/ml) was used as a reference standard. Various concentrations (5, 10 and 20 mg/ml) of both plant extracts were tested and results were expressed in terms of time taken for paralysis (PT) and death (D) of worms. The potency of the above extracts was found to be inversely proportional to PT and D. Dose dependent activity was observed in the plant extracts. At higher dose of 20 mg/ml lessThan i greaterThan C. lessThan /i greaterThan lessThan i greaterThan zeylanicum lessThan /i greaterThan showed significant activity as compared to lessThan i greaterThan S. aromaticum lessThan /i greaterThan .
