【 摘 要 】
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 new compounds 1–2, and compounds 5, 6, 8, 9, 11, 14–17, 21–25, 27–29, 31, 33, 34, 36, and 37 were isolated from the genus Xanthoceras for the first time. Compounds 1–37 did not show strong cytotoxicity against the four tested tumor cell lines (A549, HepG2, MGC-803, and MFC) compared to paclitaxel and under the conditions tested in the anti-tumor assay, but compounds 3, 4, 7, 8, 10, 18–20, 25, 26, 29, 30, 32, and 35 exhibited stronger radical-scavenging activity than ascorbic acid in a 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt assay. This was the first report on the anti-tumor and radical-scavenging activities of the polyphenols isolated from X. sorbifolia husks. Overall, the present study contributed valuable information concerning X. sorbifolia husks use in medicine and pharmacology.
