title: Isolation and identification of new phytoconstituents from the fruit extract of Amomum subulatum Roxb.
abstract: The fruits of Amomum subulatum Roxb. (Zingiberaceae) (large cardamom), cultivated in the northern Himalayas, are used to treat stomach disorders, pulmonary diseases and liver complaints. Phytochemical investigation of the fruits led to the isolation of four new chemical compounds characterised as geranil-3(10)-en-9-olyl octadec-9-enoate, geranil-3(10)-en-9-carboxyl-β-D-arabinopyranoside, geranilan-9-carboxy-α-L-arabinopyranoside and stigmast-5-en-3β-ol-3β-D-arabinopyranosyl-2'-(3″-methoxy) benzoate-3'-octadec-9‴,12‴,15‴-trienoate, along with the known compounds oleodilinolein and glyceryl trilinoleniate on the basis of spectral data analysis.
