New diarylheptanoids from Alpinia pinnanensis.
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 beta-sitosterol as a mixture, and beta-sitosterol 3-O-beta-D-glucopyranoside were isolated from the rhizomes of Alpinia pinnanensis T. L. WU et SENJEN (Zingiberaceae). Their structures were elucidated by spectroscopic analyses.
