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-β-D-(6'-O-β-D-xylopyranosyl)glucopyranoside and Z-hex-3-en-1-ol 1-O-β-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-β-D-glucopyranoside, 3R,9R,7E-megastigma-5,7-diene-3,9-diol 3,9-di-O-β-D-glucopyranoside, and 5R,6S,7E-megastigma-3-on-7-en-9-ol 9-O-β-D-(6'-O-β-D-xylopyranosyl)glucopyranoside, respectively.
