【摘要】 通过对新棕、陈棕、陈棕炭及市售止血药血安（棕榈子提取物的干浸膏）等的水、醇、乙酸提取液的薄层层析和对小鼠、家兔凝血时间的测定，结果表明新棕、陈棕、陈棕炭、血安等主要斑点的数量、荧光、Ｒｆ值相同，由此推断其止血的主要有效成分是相同的。２０％陈棕炭水煎液即有显著的凝血效果（Ｐ＜０．０５），３０％以上浓度时，其凝血作用与同浓度的血安比，似有超过血安的趋势。通过时效关系的测定，发现陈棕炭体内有效浓度维持２４小时。更多还原

【Abstract】 Abstract The author reported that 20% boiled solution of old palm carbonhad a significant hemostatic effect and the 30%boiled Solution of old palm carbon had the same hemostatic effect as that of Xue An (血安 hemostatic drug extractedfrom the seed of palm ) on mice and rabbit’s. Analyzed with thin layer chromatography, the water. alcohol and otherextracts of the new and old palm fibre. the old palm carbon and the XueAn had the same number of main spots andthe same fluorescence and Rf value. The author deduced that these different palm products had the same main effective compositions.更多还原
