Kobayashi Y, Takeda T, Ogihara Y
New triterpenoid glycosides from the leaves of Bupleurum rotundifolium L
Chemical and Pharmaceutical Bulletin 29(8) (1981) 2222-2229
 

Two new triglycosides of oleanane-type triterpenes, rotundioside E (3) and F (1), isolated from the leaves of Bupleurum rotundifolium L. were identified as 16α,28-dihydroxyoleana-11,13(18)-dien-3β-yl α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-(1→2)-β-D-fucopyranoside (3) and 13β,28-epoxy-16α-hydroxyoleana-11-en-3β-yl α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-(1→2)-β-D-fucopyranoside (1), respectively, on the basis of chemical and spectroscopic evidence.

Xiong Q, Shi D, Mizuno M
Flavonol glucosides in pericarps of Zanthoxylum bungeanum
Phytochemistry 39 (1995) 723-725
 

Two new flavonol glucosides, viz. quarcetin 3′,4′-dimethyl ether 7-glucoside and tamarixetin 3,7-bis-glucoside, together with hyperin, quercetin, quercitrin, foeniculin, isorhamnetin 7-glucoside, rutin, 3,5,6-trihydroxy-7,4′-dimethoxyflavone, arbutin, sitosterol β-glucoside, l-sesamin and palmitic acid were isolated from the pericarps of Zanthoxylum bungeanum. Their structures were established by spectroscopic and spectrophotometric methods.
