title: Three new flavonoids, hippophins K-M, from the seed residue of Hippophae rhamnoides subsp. sinensis.
abstract: Three new flavonol glycosides (1-3), hippophins K-M, were isolated from the seed residue of Hippophae rhamnoides subsp. sinensis. The chemical structures of these three new compounds were identified by 1D, 2D NMR, mass spectroscopy and high resolution electrospray ionization mass spectrometry spectroscopic data and by comparison with the literature data. This report is a continuous research work on the systematic chemical investigation of plants of the genus Hippophae in our laboratory.
