Abstract:
The present study investigates the phyto-chemical analysis, phytotoxic activity and insecticidal activity of the
stem and root tissues of medicinally important Periploca hydaspidis. All the extracted samples exhibited the phytotoxic activity. The data confirmed that water was the best solvent to extract the phytotoxic compounds from stem and root tissues. Roots extracted with different solvents exhibited better phytotoxic potential than samples obtained from the stem tissues. Samples extracted in methanol and water from both stems and roots tissues were active against the subject insects while hexane, ethyl acetate and butanol extracted samples in both parts exhibited no insecticidal activity. Water extracted samples of the stem and root exhibited better insecticidal activity compared with methanol extracted samples. Tribolium castaneum and Rhizopertha dominica were more sensitive in both the cases than Callosobruchus maculates. The plant contained alkaloids, flavonoids, carbohydrate, proteins and saponins.
