Abstract

Inula helianthus-aquatica C. Y. Wu is a traditional medicinal plant used to treat some cancers in folk herbal medicine of Yunnan, China. Bigelovin, a sesquiterpene lactone isolated from this herb, potently inhibits the growth of a panel of eight cancer cell lines, especially in human monoblastic leukemia U937 cells with an IC50 value of 0.47 µM. Characteristic morphological features of apoptosis were observed in U937 cells treated with bigelovin. Annexin V and nuclear DNA content distribution assays showed that the percentage of Annexin V positive cells increased to 8.86% (24 h) with 1 µM bigelovin treatment, and cells treated with bigelovin at this concentration apparently arrested at G0/G1 phase compared with the control. These data suggested that cytotoxic effect of bigelovin on U937 cells involves induction of apoptosis, and the cell cycle is arrested at G0/G1 phase. Copyright © 2008 John Wiley & Sons, Ltd.

Abstract

The extraction, fractionation and recognition of flavonoids from the ethanolic extract of young twigs and leaves of C. bonduc were carried out. In addition, cytotoxic study of the flavonoids on two cancer cell lines, BGC-823 and HeLa was carried our using sulphorhodamine B assay. Seven flavonoids, six of which are being reported for the first time in this plant, were isolated. Their structures were identified by MS and NMR spectroscopic methods. Petroleum ether, ethyl acetate and water fractions exhibited moderate cytotoxic activity against HeLa cells. Five compounds showed cytotoxic activity against HeLa cell in comparison with Paclitaxel, while only one compound showed a good degree of cytotoxic activity against BGC-823 cell in comparison to Paclitaxel. The results obtained showed a structure - activity relationship.

Abstract

Five flavone C-glycosides were isolated from the methanol extract of the degrease seeds of Ziziphus jujuba var. spinosa though various column chromatography methods including silica gel, MPLC, and HPLC. The structures were elucidated as 6"-feruloyl- 6'''-vanillylspinosin(1), 6",6'"-diferuloylspinosin(2), spinosin(3), swertisin(4) and isoswertisin(5) based on the NMR and MS spectral data. 1 is a new compound.

Abstract

Chemical constituents in ethyl acetate and butanol fractions of ethanol extracts from Acorus tatarinowii were separated by column chromatography. Bufo skeletal muscle fatigue model was established to study the anti-fatigue activity of separated compounds. Five compounds were separated and identified by spectroscopic analysis as acoramone(1),cycloartenone(2),2,4,5-trimethoxyl-2'-butoxy-1,2-phenyl propandiol(3),5-hydroxymethyl furfural(4), and 5-butoxymethyl furfural(5). Compound 3 was a new compound, and compounds 2 and 5 were separated from this plant for the first time. Compound 4 exhibited a notable anti-fatigue activity.
