New constituents of the leaves of Alpinia flabellata

J Nat Prod. 2001 Apr;64(4):515-7. doi: 10.1021/np0004855.

Abstract

Two new compounds were isolated from the leaves of Alpinia flabellata. The structures of these compounds were determined by a combination of NMR techniques and HREIMS as 4-hydroxy-2-(2,4,5-trimethoxyphenyl)-2E-butenal (1) and rel-labd-12-en-15(16)-olid-7-one-8R-spiro-1'-[2S-(2,4,5-trimethoxyphenyl)-3-cyclohexene] (2).
