Abstract:
Three new diarylheptanoids, called alpinnanins A-C (1-3), together with two known chalcones,
2?,4?-dihydroxy-6?-methoxychalcone and 4?,6?-dimethylchalconaringenin, two known flavanones,
alpinetin and naringenin 5-O-methyl ether, a known diarylheptanoid, (3S,5S)-trans-3,5- dihydroxy-1,7-
diphenyl-1-heptene, stigmasterol and ?-sitosterol as a mixture, and ?-sitosterol 3-O-?-D-glucopyranoside
were isolated from the rhizomes of Alpinia pinnanensis T. L. WU et SENJEN (Zingiberaceae). Their
structures were elucidated by spectroscopic analyses. ?? 2005 Pharmaceutical Society of Japan.
