FROM the leaves of Lespedeza cyrtobotrya Miquel, a deciduous shrub of the natural family Leguminosæ, M. Hasegawa and I isolated a kæmpferol glycoside which we named lespedin1,2, its structure being shown to be kæmpferol 3,7-dirhamnoside. It has also been isolated from Celastrus orbiculatus Thunberg (family Celastraceæ) by M. Kanao and M. Shimokoriyama3. When crystallized from water, lespedin had melting point 195° with or without water of crystallization (3½H2O), whereas from ethanol it melted at 234°. It thus appeared to be different from kæmpferitrin, melting point 201–203° 4.
