Isolation and Characterization of Water-soluble New Gingerlanosterol from Zingiber officinale Rhizomes

摘要

The rhizomes of Zingiber officinale after hydro-distillation of the essential oil have yielded one new compound Gingerlanosterol(Lanostan-3beta,25-diol-3beta-D-gIucopyranosyl l,4-beta-D-glucopyrano-side)from waste water of ginger along with known hexanoic phosphate.The structure of the new compound was elucidated by 500 MHz NMR aided by EI-MS,1R spectra and chemical methods.
