New minor spirostanol glycosides from Helleborus thibetanus.[Pubmed: 27834098]


Phytochemical reinvestigation of the dried roots and rhizomes of Helleborus thibetanus afforded four new minor spirostanol glycosides (1-4) and four known spirostanol glycosides (5-8). Their structures were determined on the basis of spectroscopic analyses, including 1D and 2D NMR experiments, together with HR-ESI-MS and IR measurements and the results of acid hydrolysis.


Three new steroidal saponins from Helleborus thibetanus.[Pubmed: 26821553]


Three new steroidal saponins including two spirostanol glycosides (1-2) and one furostanol glycoside 1-sulphate (3) were isolated from the dried roots and rhizomes of Helleborus thibetanus. Structures of the compounds were determined on the basis of extensive use of 1-D and 2-D NMR experiments, together with HR-ESI-MS and IR measurements, as well as the results of acid hydrolysis. Compounds 1-2 represented steroidal saponins with an unusual substitution pattern, which possessed a double bond at C-25 and were glycosylated at 1-OH.


Two new bufadienolides from the rhizomes of Helleborus thibetanus with inhibitory activities against prostate cancer cells.[Pubmed: 24697315]


Two new bufadienolide glycosides (1 and 2) with an A/B trans ring fusion together with nine known compounds (3-11) were isolated from the rhizomes of Helleborus thibetanus. The structures of new compounds were elucidated by extensive spectroscopic analyses in combination with single-crystal X-ray diffraction. The bufadienolides 1 and 3-6 exhibited potent cytotoxic activities against the prostate cancer cells.


Two new bufadienolides from the rhizomes of Helleborus thibetanus Franch.[Pubmed: 20230875]


Two new bufadienolides, named tigencaoside A(1) and tigencaoside B(2), were isolated from the rhizomes of Helleborus thibetanus Franch., along with two known bufadienolides, hellebrigenin (3) and 5beta,14beta-dihydroxy-19-oxo-3beta-[(alpha-L-rhamnopyranosyl)oxy]bufa-20,22-dienolide (4). Their structures were elucidated on the basis of extensive spectroscopic analysis. Two new compounds were evaluated for their cytotoxic activities against four strains of cultured tumor cells.
