Abstract

In this paper, the flowers of Rosa chinensis Jacq. were investigated and 14 compounds were isolated and identified, namely kaempferol (1), quercetin (2), isoquercitrin (3), afzelin (4), quercitrin (5), phenylethyl glucopyranoside (6), avicularin (7), juglanin (8), nicotiflorin (9), phenylethyl-6′-O-galloyl-β-D-glucopyranoside (10), tiliroside (11), methyl gallate (12), 8-O-methylherbacetin-3-O-β-D-sophoroside (13), gallic acid (14). Among these compounds, compounds 7, 9, 12 and 13 were isolated from R. chinensis for the first time. These compounds and extracts of R. chinensis. were studied for coagulation activity in vitro. The results showed that tiliroside (11) had good effect on promoting blood coagulation, and the effect of tiliroside was better than that of Yunnanbaiyao. Juglanin (8) and nicotiflorin (9) could significantly shorten thrombin time (TT) and significantly elevated fibrinogen (FIB), which proved that juglanin and nicotiflorin had good procoagulant effect.

月季花的化学成分及凝血作用。
本文对中国蔷薇的花进行了研究。对14个化合物进行了分离鉴定,分别为山奈酚(1)、槲皮素(2)、异槲皮素(3)、阿夫泽林(4)、槲皮苷(5)、苯乙基吡喃葡糖苷(6。在这些化合物中,化合物7、9、12和13是第一次从R.chinensis中分离得到。这些化合物和R.chinensis的提取物。研究了体外凝血活性。结果表明,tililoside(11)具有良好的促凝血作用,且tililosid的促凝血效果优于云南白药。Juglanin(8)和nicotiflorin(9)可显著缩短凝血酶时间(TT),显著升高纤维蛋白原(FIB),证明Juglanin和nicotifrorin具有良好的促凝作用。
