The effect of OCC is dose-time dependent. By using the LKB2277 Bioactivity Monitor,we determined the heat production rate of HL-60 cells treated by OCC at different concentrations. It was found that the heat production rate of HL-60 cell treated by OCC gradually decreased to that of normal human neutrophiles.展开更多
A new malonylated dammarane-type triterpene oligoglycoside,named malonyl-notoginsenoside-R4(1),was isolated from the fresh root of Panax ginseng C.A.Mey.The structure of malonyl-notoginsenoside-R4 was determined as 3-...A new malonylated dammarane-type triterpene oligoglycoside,named malonyl-notoginsenoside-R4(1),was isolated from the fresh root of Panax ginseng C.A.Mey.The structure of malonyl-notoginsenoside-R4 was determined as 3-O-[6-O-malonyl-β-D-glucopyranosyl(1→2)-β-D-glucopyranosyl]-20-O-[β-D-xylopyranosyl(1→6)-β-D-glucopyranosyl(1→6)-β-D-glucopyranosyl]-20(S) protopanaxadiol on the basis of physicochemical properties and spectral analysis.展开更多
