摘要:

初步研究白及非多糖组分(BS-80EE)中止血活性成分。采用超高压液相色谱-电喷雾-四级杆-飞行时间串联质谱(UHPLC-ESI-Q-TOF MS)联用技术分析BS-80EE中化学成分;利用二磷酸腺苷(ADP)、凝血酶(THR)诱导的血小板聚集实验和小鼠凝血时间(CT)实验初步评价其止血活性。结果显示,从BS-80EE中共成功指认了12个化合物。其中4-hydroxymethylphenyl β-D-glucoside(1)、blestroside(5)、gymnoside I(7)、gymnoside Ⅸ(14)、armatuside(17)能显著促进血小板聚集作用。4-Hydroxymethylphenyl β-D-glucoside(1)、α-isobutylmalic acid(3)、blestroside(5)、gymnoside I(7)、militarine(8)、gymnoside Ⅸ(14)、1-p-hydroxybenzyl-4-methoxyphenanthrene-2,7-diol(18)可显著缩短肝素化小鼠的CT值。该研究结果初步明确了BS-80EE发挥止血的物质基础。

Abstract:

To investigate the hemostatic active compounds from the non-polysaccharide fraction of Bletilla striata(BS-80EE).UHPLC-ESI-Q-TOF MS was used to analyze the chemical constituents of BS-80EE.The hemostatic activities of compounds were evaluated through testing their effects on platelet aggregation induced by ADP and THR,and their CTs of heparinized mice.The results showed twelve compounds were identified from the BS-80EE.Among them,compounds 4-hydroxymethylphenyl β-D-glucoside (1),blestroside (5),gymnoside I (7),gymnoside Ⅸ (14) and armatuside (17) showed significant promoted platelet aggregation,and 4-hydroxymethylphenyl β-D-glucoside (1),α-isobutylmalic acid (3),blestroside (5),gymnoside I (7),militarine (8),gymnoside Ⅸ (14) and 1-p-hydroxybenzyl-4-methoxyphenanthrene-2,7-diol (18) could significantly shortened the CTs of heparinized mice.This results initially illuminated the hemostatic active ingredients of Bletilla striata.
