xanthoceras sorbifolium/悪性腫瘍

The high edible oil content of Xanthoceras sorbifolia Bunge seeds contributes to its economic value. In this study, we analysed the barrigenol-like triterpenoids derived from X. sorbifolia husks. We also identified anti-tumour agents that could enhance the health benefits and medicinal value of X.

Xanthoceras sorbifolia Bunge is widely used as healthy food material and folk medicine in China. Phytochemical investigation on its seeds oil leavings has led to the isolation and identification of seven new oleanane-type triterpenoid saponins named sorbifoliasides A-F (1-6) and bunkankasaponin F

Xanthoceras sorbifolia Bunge. is used in traditional medicine in North China. To evaluate the anti-tumor and radical-scavenging activities of X. sorbifolia husks polyphenols and determine their structure-activity relationships, 37 polyphenols 1-37 were obtained by bioassay-guided fractionation. Two

A new triterpenoid saponin, 3-O-[(3-O-alpha-l-arabinofuranosyl-2-O-beta-d-galactopyranosyl)-beta-d-glucuronopyranosyl]-21,22-di-O-angeloyl-R1-barrigenol (1), together with four known triterpenoids, have been isolated from the husks of Xanthoceras sorbifolia Bunge. Their structures were elucidated

Two new isoxazoline compounds, 1-oxa-2-azaspiro[4.5]dec-2-ene-8β-ol (1) and 1-oxa-2-azaspiro[4.5]dec-2-ene-8α-ol (2), were isolated from the husks of fruits of Xanthoceras sorbifolia Bunge and their structures were determined by spectroscopic analyses, including X-ray crystallography, HRESI-MS, UV,

Phytochemical analysis of the extract from the seed oil leavings of Xanthoceras sorbifolia Bunge led to the isolation of five new oleanane-type triterpeniod saponins, sorbifoliasides G-K (1-5). Their structures were elucidated on the basis of spectroscopic analysis and chemical derivatization. To

The Xanthoceras sorbifolia Bunge husks were known for their abundant triterpenoids resource, which contributed to many bioactivities, such as antitumor, antiinflammatory and neuroprotection. The present study has led to the purification of a new triterpenoid saponin, 21β-O-acetyl-xanthohuskiside A

Four new oleanane-type triterpene saponins, xanifolia-Y0 (1), xanifolia-Y2 (2), xanifolia-Y3 (3), and xanifolia-Y7 (4), were isolated from the husks of Xanthoceras sorbifolia along with two known analogues, xanifolia-Y8 (5) and xanifolia-Y10 (6). The structures of 1-4 were determined by

Two new triterpenoids 3-O-beta-d-glucopyranosyl (1-->6)-beta-d-glucopyranosyl, 28-O-beta-d-glucopyranosyl (1-->6) [alpha-l-rhamnopyranosyl (1-->2)]-beta-d-glucopyranosyl, 16-deoxybarringtogenol C (1) and 22-O-acetyl-21-O-(4'-O-angeloyl)-beta-d-fucopyranosyl theasapogenol B (2), were isolated from

Two new triterpenes, 22-angeloyl-21-epoxyangeloylbarringtogenol C (1) and 21,22-diangeloyl-24-hydroxy-R(1)-barrigenol (2), and the known 21,22-diangeloyl-R(1)-barrigenol (3) were isolated from the husks of Xanthoceras sorbifolia Bunge. Their structures were elucidated based on detailed NMR analysis.

Two new triterpenoid saponins (1, 2) and a known saponin (3) were isolated from the husks of Xanthoceras sorbifolia Bunge., and their structures were elucidated as 3-O-β-D-glucopyranosyl(1 → 6)-[angeloyl(1 → 2)]-β-D-glucopyranosyl-28-O-α-L-rhamnopyranosyl(1 → 2)-[β-D-glucopyranosyl(1 →

Two new triterpenoid saponins (1, 2) and a known sapogenin (3) were isolated from the dried carpophore of Xanthoceras sorbifolia Bunge. (Sapindaceae), and their structures were established as 3-O-beta-d-glucopyranosyl, 28-O-[alpha-l-rhamnosyl (1 --> 2)]-beta-d-glucopyranosyl 16-deoxybarrin-gtogenol

Two new oleanane-type pentacyclic triterpenoid saponins were isolated from the husks of Xanthoceras sorbifolia Bunge and their structures were elucidated as 3-O-β-D-glucopyranosyl (1 → 6)-β-D-glucopyranosyl-28-O-α-L-rhamnopyranosyl (1 → 2) [β-D-glucopyranosyl (1 → 6)]
