Non-alkaloid constituents from Stemona sessilifolia

Fourteen non-alkaloid constituents were firstly isolated from the roots of Stemona sessilifolia.On the basis of the spectral data,they were determined as stigmasterol (1),4-methoxy benzoic acid (2),benzoic acid (3),3,4-dimethoxyphenol (4),4-methyl benzoic acid (5),4-hydroxy benzoic acid (6),4-hydroxy-3-methoxy benzoic acid (7),4-hydroxy-3,5-dimethoxy benzoic acid (8),3,3′-bis(3,4-dihydro-4-hydroxy-6-methoxy)-2H-1-benzopyran (9),4-hydroxy-3-methoxy benzaldehyde (10),lupan-3-one (11),chlorogenic acid (12),daucosterol (13) and 3-feruoyl-chinasueure (14).Compounds 5-14 were isolated from the genus Stemona for the first time.
