This paper reviews our investigations on the chemical constituents of several kinds of botanically identified licorice roots, which led to the characterization of 13 then-new glucuronide-saponins named licorice-saponins (A–L), apioglycyrrhizin, and araboglycyrrhizin,together with glycyrrhizin and 18α-glycyrrhizin and also of 49 kinds of phenolic compounds and their glycosides (11 then-new). The restoration-promoting activity of licorice-saponin B2 for CCl4-intoxicated hepatocyte function and the structure–sweetness relationship of saponins were discussed. Biologically interesting, but isolable in minor quantities, several licorice-saponins were favorably synthesized from abundantly available glycyrrhizin. With 15 saponins and 49 phenolic compounds (including their glycosides) at hand, chemical evaluation of licorice root processings was undertaken. It was shown that the cortex contained a rich amount of phenolic compounds, whereas the xylem was rich in phenolic glycosides and the saponins contained were richer in the xylem than in the cortex. It was also found that roasted licorice root contained an increased amount of glycyrrhetic acid monoglucuronide, which was secondarily formed from lycyrrhizin through thermal hydrolysis and was known to taste 5 times sweeter than glycyrrhizin. 红色的地方实在不太明白,尤其是then-new在化学里是什么意思。。。好心人帮帮忙Orz [ Last edited by icetear on 2012-11-3 at 21:24 ] |

“glucuronide-saponins”是“葡糖苷酸皂苷”; “apioglycyrrhizin”是“甘草次酸-3-芹糖葡萄糖醛酸甙”‘ “araboglycyrrhizin”是“甘草次酸-3-阿拉伯糖葡萄糖醛酸甙”; “glycyrrhetic acid monoglucuronide”是“糖醛酸基甘草次酸/单葡糖苷酸基甘草次酸”。 “then-new”应该是“当时新发现”的意思吧。 “Biologically interesting, but isolable in minor quantities, several licorice-saponins were favorably synthesized from abundantly available glycyrrhizin”这句话的意思应该是“一些具有生物活性功能的甘草皂苷尽管分离量少,但可通过大量的甘草酸合成得到。” 建议LZ找相应的中文文献,然后参考文章中甘草的化学成分名字(一般中英文都有)。 |
