对乳香树(Boswellia papyrifera)的茎皮提取物进行植物化学研究,得到两种新的二苯乙烯苷,反式-4 ',5-二羟基-3-甲氧基二苯乙烯-5-O-{α-L-吡喃鼠李糖基-(1->2)-[α-L-吡喃鼠李糖基-(1->6)]-β-D-吡喃葡萄糖苷(1),反式-4',5-二羟基-3-甲氧基二苯乙烯-5-O-[α-L-吡喃鼠李糖基-(1->6)]-β-D-吡喃葡萄糖苷(2),和一种新的三萜,3 α-乙酰氧基-27-羟基-20(29)-烯-24-酸(3),沿着五种已知化合物,11-酮基-β-乳香酸(4)、β-榄香酸(7)、3 β-乙酰氧基-11-酮基-β-乳香酸(8)、β-乳香酸(9)和β-谷甾醇(10)。二苯乙烯苷对磷酸二酯酶I和黄嘌呤氧化酶有明显的抑制作用。三萜类化合物(3-9)具有脯氨酰内肽酶抑制活性。
Phytochemical investigation of the stem bark extract of Boswellia papyrifera afforded two new stilbene glycosides, trans-4',5-dihydroxy-3-methoxystilbene-5-O-{alpha-L-rhamnopyranosyl-(1-->2)-[alpha-L-rhamnopyranosyl-(1-->6)]-beta-D-glucopyranoside (1), trans-4',5-dihydroxy-3-methoxystilbene-5-O-[alpha-L-rhamnopyranosyl-(1-->6)]-beta-D-glucopyranoside (2), and a new triterpene, 3alpha-acetoxy-27-hydroxylup-20(29)-en-24-oic acid (3), along with five known compounds, 11-keto-beta-boswellic acid (4), beta-elemonic acid (7), 3beta-acetoxy-11-keto-beta-boswellic acid (8), beta-boswellic acid (9), and beta-sitosterol (10). The stilbene glycosides exhibited significant inhibition of phosphodiesterase I and xanthine oxidase. The triterpenes (3-9) exhibited prolyl endopeptidase inhibitory activities.
