Abstract:
A new glycocerebroside (1), along with one reported one (2), was isolated from the ethanol extract of Sagina japonica (Caryophyllaceae) and was fully characterized. The structures of two compounds were identified as (2S, 3S, 4R, 8E)-1-(beta-D-glucopyranosyl-3, 4-dihydroxy-2-[(R)-2'- hydroxypalmitoyl]amino-8-heptadecaene (1) and (2S, 3R, 8E)-1-(beta-D-glucopyranosyl-3-hydroxy-2-[(R)-2'-hydroxypalmitoyl]amino-8-octadecaene (2) by using spectroscopic methods ((1)H, (13)C, and 2D NMR, MS) and chemical degradation.
