Three new oleanane-type triterpenoid saponins named celosins H (1), I (2), and J (3) were isolated from the seeds of Celosia argentea L. Their structures were characterized as 3-O-β-d-xylopyranosyl-(1 → 3)-β-d-glucuronopyranosyl-polygalagenin 28-O-β-d-glucopyranosyl ester, 3-O-β-d-glucuronopyranosyl-medicagenic acid 28-O-β-d-xylcopyranosyl-(1 → 4)-α-l-rhamnopyranosyl-(1 → 2)-β-d-fucopyranosyl ester, and 3-O-β-d-glucuronopyranosyl-medicagenic acid 28-O-α-l-arabinopyranosyl-(1 → 3)-[β-d-xylcopyranosyl-(1 → 4)]-α-l-rhamnopyranosyl-(1 → 2)-β-d-fucopyranosyl ester by NMR, MS, and chemical evidences, respectively. In our opinion, celosins H–J could be used as chemical markers for the quality control of C. argentea seeds. 相似文献

A new triterpenoid saponin named clematichinenoside AR2, along with the six known compounds, was isolated and characterized from Clematis chinensis Osbeck (Ranunculaceae), a commonly used traditional Chinese medicine with anti-inflammatory and anti-rheumatoid activities. The structure of the new saponin was elucidated as 3-O-β-[(O-α-l-rhamnopyranosyl-(1 → 6)-O-β-d-glucopyranosyl-(1 → 4)-O-β-d-glucopyranosyl-(1 → 4)-O-β-d-ribopyranosyl-(1 → 3)-O-α-l-rhamnopyranosyl-(1 → 2)-α-l-arabinopyranosyl)oxy]olean-12-en-21α-hydroxy-28-oic acid-O-α-l-rhamnopyranosyl-(1 → 4)-O-β-d-glucopyranosyl-(1 → 6)-β-d-glucopyranosyl ester (1) by spectral analysis and chemical methods. The effects of two major saponins (clematichinenosides AR and AR2) on the secretion of TNF-α in murine peritoneal macrophages induced by lipopolysaccharides were further investigated. The result indicated that a majority of triterpenoid saponins of this herb may be useful in the exploration of lead compounds for the treatment of some autoimmune diseases. 相似文献
