Abstract
The basic fractions of methanol and water extracts of a crude drug, Pinelliae Tuber, obtained from Pinellia ternata, showed a relaxant action and antihistamine-like action upon an isolated rectum of Japanese quails. And l-ephedrine hydrochloride was isolated in the yield of 0.002% as the active principle.This publication has 0 references indexed in Scilit:
