Cyclooxygenase-2 inhibitory cerebrosides from phytolaccae radix.
A mixture of cerebrosides, called poke-weed cerebrosides, was purified from Phytolaccae Radix (Phytolaccaceae) and characterized as 1-O-beta-D-glucopyranosides of phytosphingosine type ceramides comprised of a common long chain base (2S,3S,4R,8Z)-2-amino-8-octadecene-1,3,4-triol and fatty acids. The fatty acyl chain of ceramide moieties was determined as (2R)-2-hydroxypentacosanoic acid, (2R)-2...
متن کاملRadix phytolaccae on tissue metabolomics in rats by gas chromatography-mass spectrometry
Traditional Chinese medicine Radix phytolaccae is the dried root of Phytolacca acinosa Roxb and Phytolacca americana L. Radix phytolaccae has multiple efficacies of antibiosis, antivirus, antiinflammatory, antitumor, enhancing immunity, eliminating phlegm and relieving asthma. In this study, we developed a tissue (liver, kidney and heart) metabolomic method by gas chromatography-mass spectromet...
متن کاملCerebrosides from the roots of Serratula chinensis.
A new cerebroside, 1-O-beta-D-glucopyranosyl-(2S,3R,8E)-2-[(2'R)-2-hydroxy- palmitoylamino]-8-octadecene-1,3-diol, along with aralia cerebroside and 1-O-beta-D- glucopyranosyl-(2S,3S,4R,8E)-2-[(2'R)-2-hydroxybehenoylamino]-8-octadecene-1,3,4-triol were isolated from the roots of Serratula chinensis S. Moore. The structure of the new cerebroside was established by spectroscopic and chemical mean...
متن کاملCerebrosides and a monoacylmonogalactosylglycerol from Clinacanthus nutans.
A mixture of nine cerebrosides and a monoacylmonogalactosylglycerol were separated from the leaves of Clinacanthus nutans. The structures of the cerebrosides were characterized as 1-O-beta-D-glucosides of phytosphingosines, which comprised a common long-chain base, (2S,3S,4R,8Z)-2-amino-8(Z)-octadecene-1,3,4-triol with nine 2-hydroxy fatty acids of varying chain lengths (C(16), C(18), C(20-26))...
متن کاملStructural Characterisation of a Polysaccharide from Radix Ranunculus ternati
A water soluble polysaccharide, HB-1, with a molecular weight of 23,930, was isolated from radix Ranunculi ternati. by hot water extraction, ethanol precipitation, deproteination，ultrafiltration and gel-filtration column chromatography. Its sugar composition was determined by GLC as Glc, Ara, and Gal in a molar ration of 16.071: 2.722: 1. And the absolute configuration of Glc was identified as ...
