Three new neolignan glycosides, (7R,8S)-4-hydroxy-3,3'-dimethoxy-8,4'-oxyneoligna-7,9,9'-triol-4-O-β-d-glucopyranosyl-(1 → 4)-β-D-glucopyranoside (1), (7R,8S)-4-hydroxy-3,5'-dimethoxy-4',7-epoxy-8,3'-neoligna-9,9'-diol-9'-O-β-d-glucopyranosyl-4-O-[β-d-glucopyranosyl-(1 → 4)]-β-D-glucopyranoside (2), and (7R,8S)-4-hydroxy-3,5,5'-trimethoxy-4',7-epoxy-8,3'-neoligna-9,9'-diol-9'-O-β-d-glucopyranosyl-4-O-[β-d-glucopyranosyl-(1 → 4)]-β-D-glucopyranoside (3), one new phenolic glycoside, securiphenoside B (4) and two new hemiterpene glycosides, securiterpenoside E-F (5-6) were isolated from the stems of Securidaca inappendiculata Hassk. Their structures were elucidated on the basis of 1D and 2D NMR, HRESIMS, CD and chemical evidence. Furthermore, compound 2 showed moderate hepatoprotective activity compared with bicyclol in vitro.

UI	MeSH Term	Description	Entries
D002681	China	A country spanning from central Asia to the Pacific Ocean.	Inner Mongolia,Manchuria,People's Republic of China,Sinkiang,Mainland China
D006027	Glycosides	Any compound that contains a constituent sugar, in which the hydroxyl group attached to the first carbon is substituted by an alcoholic, phenolic, or other group. They are named specifically for the sugar contained, such as glucoside (glucose), pentoside (pentose), fructoside (fructose), etc. Upon hydrolysis, a sugar and nonsugar component (aglycone) are formed.
