title: Two new compounds from transgenic Panax quinquefolium.
abstract: A new ceramide and a new poly-hydroxyl octadecenoic acid were isolated from transgenic crown galls of Panax quinquefolium. Their structures were elucidated as (2S, 3S, 4R, 20E)-2-[(2'R)-2'-hydroxyl-palmitoyl-amino]-20-hexacosene-1, 3, 4-triol (1) and 12, 13, 15-trihydroxy-9-octadecenoic acid (2) respectively on the basis of spectroscopic and chemical methods.
