Results n-Butanol extract and water extract significantly enhanced and petroleum ether extract from Bletilla colloid prominently reduced platelet maximum aggregation induced by ADP,while acetic ether extract had no effect.

• 结果白及正丁醇提取部位和水溶性部位可显著升高腺苷二磷酸(ADP)诱导的血小板最大聚集率,而乙酸乙酯提取部位可显著抑制ADP诱导的血小板聚集,石油醚提取部位对ADP诱导的血小板聚集无显著影响。 各提取部位对血小板数无显著影响。
