Two new steroidal saponins (1 and 2), along with four known ones (3 ∼ 6) were obtained from the roots and rhizomes of Maianthemum henryi, their structures were determined to be spirost-5, 25(27)-diene-lβ, 3β-diol 1-O-α-L-rhamnopyranosyl-(1 → 2)-4-O-acetyl-β-D-fucopyranoside (1), (23S,
For the first time three different natural compounds, isolated from hairy roots of Astragalus membranaceus, cultivated in airlift bioreactor were tested for their cytotoxic potential and apoptosis induction in a panel of human tumor cell lines. Root cultures, cultivated in bioreactor gave 18.5 g
We have previously demonstrated that the total saponins of Astragalus membranaceus (AST) possess potential anti-tumorigenic effects in human colon cancer cells and tumor xenografts. In the present study, the proapoptotic effects of AST were investigated in native and cytokine-induced HT-29 cells to
As an attempt to search for bioactive natural products exerting antiinflammatory activity, we have isolated two saponins were isolated from the aerial portion of Pleurospermum kamtschaticum (Umbelliferae) by nitrite assay activity-directed chromatographic fractionation. They were identified as
Diosgenin and diosgenyl saponins as the major bioactive compounds isolated from dietary fenugreek seeds, yam roots, etc. possessed strong antitumor effects. To understand their detailed antitumor mechanisms, a fluorophore-appended derivative of diosgenin [Glc/CNHphth-diosgenin (GND)] was
A purified mixture containing mostly saponins (PMS) from Astragalus corniculatus Bieb. was used in an in vivo model to demonstrate its protective effect against myeloid Graffi tumour in hamsters. Survivability, tumour growth and tumour transplantability were followed. Comparative studies revealed
OBJECTIVE
To investigate the inhibition of three C2 steroidal saponins from Cynanchum auriculatum on the cell growth and cell cycle of human lung cancer A549 cells.
METHODS
A549 cells were exposed to three C21 steroidal saponins of different concentrations (5, 10, 20, 40, 60, 80, 100 micromol L(-1))
Two new steroidal saponins (1 and 2) were isolated from the dried bulbs of Allium macrostemon Bunge. Their structures were elucidated by the spectral data as 26-O-beta-D-glucopyranosyl-5alpha-furost-25 (27)-ene-3beta, 12beta, 22, 26-tetraol-3-O-beta-D-glucopyranosyl (1-->2) [beta-D-glucopyranosyl
The present study aimed to investigate the molecular mechanism and the effect of Saponin from Tupistra chinensis Baker (STCB) on the proliferation and apoptosis of ovarian cancer cells. To investigate the inhibitory effect of STCB on the proliferation of ovarian cancer cells, SKOV3 cells were
Twenty 13,28-epoxy and related triterpenoid saponins from Ardisia japonica were evaluated for their anti-proliferative activity on human liver cancer cells and normal liver cells. Eight saponins selectively inhibited the growth of liver cancer Bel-7402 and HepG-2 cells without affecting the survival
Bupleuri Radix (Chai-hu in Chinese and Saiko in Japanese) is one of the most important traditional Chinese crude drugs for treating hepatitis malaria and intermittent fever. B. kaoi is one of the Bupleurum spp. families locally found in Taiwan. The effects of saponin-enriched fraction (SEF) from
Saponinum album (SAP) is a complex mixture of triterpene saponins from Gypsophila paniculata L. Although most of the saponins from SAP are characterized, the separation of pure saponins remains time consuming and costly, involving different chromatographic techniques. Recently it was shown that SAP
Five steroidal saponins from Camassia leichtlinii showed higher cytotoxicity against human oral squamous cell carcinoma cells HSC-2, as compared to normal human gingival fibroblasts HGF. The tumor specificity of saponins varied considerably from sample to sample, but was generally higher than that
Segetoside I is a plant-derived bisdesmosidic saponin from Vaccaria segetalis (Neck) with reported anticancer activities. This development has raised an interest in the therapeutic potential of segetoside I. Here, we report the in vitro and in vivo antitumor activities of segetoside I against some
BACKGROUND
Research has indicated that Herba Patriniae can suppress the growth of Several kinds of tumor cells in vitro and in vivo, thus displaying favorable antitumor activity. However, research regarding the effect of saponins of Patrinia villosa against CRC cell has not been reported. In the
