STUDIES ON THE FLAVONOIDS PRESENT IN CHINESE DRUGS——Ⅷ.STUDIES ON THE COMPONENT OF YE-JU-HUA,THE DRY FLOWER OF CHRYSANTHEMUM INDICUM L.(I.)

A flavoneglucoside has been isolated from Chrysanthemum indicum L. which is identified as acacetin-7-rhamnosidoglucoside and is identical with buddleoglucoside. There has also been isolated a crystalline,γ-lactone, m.p. 213℃, which has the empirical formula C₁₅H₂₈O₄α_D^21.5=+22.5°and vco at 1770 cm^-1. The respective yields were 0.72% and 0.1%.
