摘要: Antioxidative substances were isolated from the leaves of Rhododendron simsii. These a triterpene and flavanone glycoside, together with known matteucinol two benzoic acid derivatives. Their structures characterized as 19,24-dihydroxyurs-12-en-3-one-28-oic 7-O-beta-D-apiofuranosyl-(1-->6)-beta-D-glucopyranosylmatteucinol by spectroscopic analysis.
