From the leaves of Alangium platanifolium var. platanifolium collected in Fukuoka Prefecture, Japan, three megastigmane diglycosides (1-3) were isolated, along with two known compounds, benzyl alcohol 7-O-beta-D-(6'-O-beta-D-xylopyranosyl)glucopyranoside and Z-hex-3-en-1-ol 1-O-beta-D-glucopyranoside. The structures of the new compounds, named platanionosides A (1), B (2), and C (3) were elucidated by spectroscopic evidence to be 3S,5R,6R,9R, 7E-megastigma-3,9-diol 3,9-di-O-beta-D-glucopyranoside, 3R,9R, 7E-megastigma-5,7-diene-3,9-diol 3,9-di-O-beta-D-glucopyranoside, and 5R,6S,7E-megastigma-3-on-7-en-9-ol 9-O-beta-D-(6'-O-beta-D-xylopyranosyl)glucopyranoside, respectively.
从采自日本福冈县的八角枫（Alangium platanifolium var. platanifolium）叶片中，分离得到了三种巨大戟烷二糖苷（1 - 3），以及两种已知化合物，苄醇7 - O - β - D -（6'- O - β - D - 吡喃木糖基）吡喃葡萄糖苷和Z - 己 - 3 - 烯 - 1 - 醇1 - O - β - D - 吡喃葡萄糖苷。通过光谱证据阐明了新化合物的结构，分别命名为八角枫苷A（1）、B（2）和C（3），它们依次为3S，5R，6R，9R，7E - 巨大戟烷 - 3，9 - 二醇3，9 - 二 - O - β - D - 吡喃葡萄糖苷、3R，9R，7E - 巨大戟烷 - 5，7 - 二烯 - 3，9 - 二醇3，9 - 二 - O - β - D - 吡喃葡萄糖苷和5R，6S，7E - 巨大戟烷 - 3 - 酮 - 7 - 烯 - 9 - 醇9 - O - β - D -（6'- O - β - D - 吡喃木糖基）吡喃葡萄糖苷。
