采用水为溶剂提取冬凌草,以多糖、总黄酮及冬凌草甲素浸出率为考查指标,研究了50、60、70、80、90、100℃不同浸提温度对冬凌草茶中3类成分浸出率的影响。结果显示冬凌草茶中含有较丰富的多糖、总黄酮及冬凌草甲素,温度对三类成分有着不同的影响,随着温度的升高,多糖浸出率由0.81%升至2.30%;总黄酮浸出率由1.73%升至4.21%,而冬凌草甲素的浸出率变化较小,成略降趋势,50℃浸出率为0.0661%,而100℃浸出率为0.0527%,可以为冬凌草茶的科学使用提供了依据。
採用水為溶劑提取鼕凌草,以多糖、總黃酮及鼕凌草甲素浸齣率為攷查指標,研究瞭50、60、70、80、90、100℃不同浸提溫度對鼕凌草茶中3類成分浸齣率的影響。結果顯示鼕凌草茶中含有較豐富的多糖、總黃酮及鼕凌草甲素,溫度對三類成分有著不同的影響,隨著溫度的升高,多糖浸齣率由0.81%升至2.30%;總黃酮浸齣率由1.73%升至4.21%,而鼕凌草甲素的浸齣率變化較小,成略降趨勢,50℃浸齣率為0.0661%,而100℃浸齣率為0.0527%,可以為鼕凌草茶的科學使用提供瞭依據。

Using extracting rate of polysaccharides, total flavonoids and oridonin as index, the plants ofRabdosia rubescens were soaked in water at different temperatures from 50 to 100℃. The results showed that polysaccharides, total flavonoids and oridonin were abundant inR. rubescens tea. The temperatures played a different roles in soakingR. rubescens tea. The extracting rates of polysaccharides and total flavonoids inR. rubescens tea all increased gradually from 50 to 100℃ with the rates as 0.81% , 1.73% to 2.30%, 4.21%, separately. On the contrary, the extracting rate of oridonina declined gradually from 50 to 100℃, with 0.0661% at 50℃ and 0.0527% at 100℃, whichprovide a basis for its scientific utilization.
