中文摘要: 探究不同生长期采收的茯苓有效成分变化规律,确定适宜的采收期。试验设4个处理组,取样测定不同生长期茯苓的水分、浸出物、多糖及三萜类化合物含量。结果表明,4个生长期的茯苓丁及茯苓皮的水分含量均没有显著性差异(P>0.05),且符合药典对茯苓水分含量的限度要求。第三生长期的茯苓丁和茯苓皮浸出物含量最高,分别为4.97%和10.28%,均显著(P<0.05)高于第一和第二生长期。第三生长期茯苓的水溶性、碱溶性多糖及总三萜含量最高,显著(P<0.05)高于第一、二生长期;第四生长期采收的茯苓相对第三生长期的有效成分含量均有所下降。前3个生长期随着茯苓生长时间的增加,其有效成分含量不断增加,但生长期达到12个月之后,茯苓的有效成分有所下降,建议茯苓的生长期在9~12个月时进行采收加工。

Abstract:To explore the changes of the effective components of Poria cocos collected in different growth periods.The contents of water,extract,polysaccharides and triterpenes of Poria cocos were detected.The results showed that the four treatement of Poria cocos butyl and Poria cocos skin moisture content were not significant difference (P>0.05),and conform to the requirements of the pharmacopoeia of Poria cocos moisture content limits.In the third growth stage,the extract contents of Poria cocos and Poria cocos skin were the highest,respectively 4.97%and 10.28%,both significantly higher than the first and second growth stages(P<0.05).The contents of water-soluble,alkali-soluble polysaccharides and total triterpene in the third growing period were the highest (P<0.05),higher than the first and second growing periods.In the fourth growing period,the contents of effective components of Poria cocos were decreased.With the increase of the growth time of Poria cocos,the content of effective ingredients increased constantly,but after the growth time reached 12 months,the effective ingredients of Poria cocos decreased,and it is suggested that the growth period of Poria cocos should be harvested at 9-12 months.
