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 β-sitosterol as a mixture, and β-sitosterol 3-O-β-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.
