Two new alkyl glycosides, heptyl vicianoside (1) and methyl 2-O-β-d-fucopyranosyl-α-l-arabinofuranoside (methyl caramboside, 4), were isolated from the sour fruit of Averrhoa carambola L. (Oxalidaceae), along with octyl vicianoside (2), cis-3-hexenyl rutinoside (3), and methyl α-d-fructofuranoside (5). Their structures were determined by spectroscopic and chemical methods. Compounds 2, 3, and 5 were obtained from the genus Averrhoa for the first time. All the compounds were evaluated for in vitro α-glucosidase, pancreatic lipase, and acetylcholinesterase inhibitory activities, but none of them were potent.
从阳桃（酢浆草科）的酸果实中分离出两种新的烷基糖苷，即庚基蚕豆糖苷（1）和2-O-β-D-呋喃岩藻糖基-α-L-阿拉伯呋喃糖苷甲酯（甲基杨桃苷，4），同时还分离出了辛基蚕豆糖苷（2）、顺式-3-己烯基芸香糖苷（3）和α-D-呋喃果糖苷甲酯（5）。通过光谱和化学方法确定了它们的结构。化合物2、3和5首次从阳桃属植物中获得。对所有化合物进行了体外α-葡萄糖苷酶、胰脂肪酶和乙酰胆碱酯酶抑制活性评估，但均无显著活性。
