从商陆科(Phytolaccaceae)植物商陆(Phytolacca esculenta Van Houtte)中分离得到四种结晶,根据化学性质和光谱(UV,IR、NMR,~(13)CNMR和MS)分析,确定结晶Ⅰ为2-羟基商陆酸(2-hydroxyl esculentic acid),结晶Ⅱ为3-O-β-D-吡喃木糖-2-羟基商陆酸,称为商陆皂甙戊,结晶Ⅲ为3-O-(β-D-吡喃葡萄糖-β-D-吡喃木糖)_(1→4)-2-羟基商陆酸,称为商陆皂甙己;结晶Ⅳ的结构正在鉴定中。2-羟基商陆酸有抗炎作用。商陆皂甙戊在本植物中系首次分得,商陆皂甙己为新化合物。 Four crystals were isolated from the Phytolacca esculenta Van Houtte (Phytolaccaceae) plant. Based on the chemical properties and spectra (UV, IR, NMR, 13CNMR, and MS), the crystallographic I was determined to be 2 2-hydroxyl esculentic acid, crystalline II is 3-O-β-D-xyloxylan-2-hydroxy phytolacotic acid, known as phytolactolide, crystalline III is 3-O- (β-D-glucopyranose-β-D-xylo-xylo-xylose)_(1→4)-2-hydroxy phytolacotic acid, known as phytolactoxin; the structure of crystalline IV is being identified. 2-Hydroxy phenacrine has anti-inflammatory effects. Pokeweed saponin was firstly obtained in this plant and Pyrophylline has been a new compound.
