Novel imine from Hemsleya macrocarpa var. clavata.
The new substance hemsleyin imine A (1) was isolated along with (2S,3S,4R,2'R)-2-(2'-hydroxytetracosanoyl-amino)-octadecan-1,3,4-triol (2), (2S,3 R,4E,8E)-1-O-beta-D-glucopyranosyl -3-hydroxy-2-(2'R-hydroxypalmitoylamino)-4,8-octadecadiene (3) from the rhizomes of Hemsleya macrocarpa var. clavata. Their chemical structures were established mainly by spectral analysis and chemical evidence. Compound 1 possesses the skeleton of an imine moiety, which is novel in natural products.
