Five new cucurbitane-type triterpenoid saponins Xuedanosides A-E (1-5) were isolated from the medicinal plant Hemsleya amabilis Diels by silica gel column, octadecylsilyl (ODS) column, and pre-HPLC techniques. Their structures were determined by spectroscopic analysis and examined alongside existing

From rhizomes and roots of Panax vietnamensis Ha et Grushv., Araliaceae, commonly known as Vietnamese Ginseng, two new acetylate saponins named vina-ginsenoside-R1 (13) and vina-ginsenoside-R2 (15) were isolated. On the basis of chemical and spectral data, 13 was formulated as monoacetyl

The rhizomes of the medicinal plant Hemsleya amabilis (Cucurbitaceae) yielded three new cucurbitane-type triterpene saponins xuedanosides K-M (1-3) by silica gel column, ODS column, and pre-HPLC techniques. The structure was determined by spectroscopic analysis and examined alongside

OBJECTIVE To study the triterpenoid saponins in Hemsleya chensnsis. METHODS The chemical constituents were isolated and purified by various chromatographic methods and their structures were elucidated on the basis of spectral analysis. RESULTS Seven known triterpenoid saponins were isolated from the

In this paper, the content of moisture, ethanol-soluble extractives, total saponins and polysaccharide of different tuber samples of Hemsleya zhejiangensis, from different localities, years and seasons, were detected based upon Chinese Pharmacopoeia 2010 version. The samples of roots, stems and

OBJECTIVE To study the chemical constituents of Hemsleya chensnsis. METHODS Various chromatographic techniques were used to separate and purify the constituents. The spectral data (MS, NMR) were obtained for structure elucidation. RESULTS Eight known triterpenoid saponins were isolated from the root
