Studies on the Chemical Constituents of Elsholtzia herb

Abstract

Several crystalline compounds isolated from Elsholtzia herb (plant, Elsholtzia ciliata (THUNB.) HYLANDER in China) were triterpenoids, steroids, and flavonoids. Their structures were identified as 9-sitosterol, β-sitosterol βglucoside, ursolic acid, 2 α-hydroxyursolic acid, tormentic acid, negletein, apigenin, and luteolin by the comparison of spectroscopic data with those of the authentic samples.
