摘 要：
以江西省靖安县三爪仑山区竹林下仿野生和大田种植 2 种种植模式的 5 年生多花黄精(Polygonatum cyrtonema Hua)茎块为研究对象,采用常压蒸汽九蒸九制古法炮制,测量黄精浸出物、多糖、总黄酮、总皂苷和总酚等化学成分含量,分析各化学成分含量的变化规律,并采用隶属函数法对各样品的品质进行综合评价.结果表明,在炮制过程中,浸出物含量均大于药典规定的45%;黄精多糖的含量随着炮制次数的增加呈下降趋势,含量低于药典规定的指标;总黄酮含量呈上升趋势;总皂苷含量呈波动趋势;总酚含量呈下降趋势,以鲜黄精含量最高;多花黄精的外观性状变化一致,随着炮制次数增加,颜色逐渐变深,最后变成黑色.通过计算各成分的隶属函数值并进行综合排名,发现竹林下仿野生黄精好于大田种植黄精,同时发现林下种植黄精在第七次炮制时的综合排名高于其他次炮制,大田种植黄精在第四次炮制的综合排名高于其他次.

摘 要：
The stems of 5-year-old Polygonatum cyrtonema Hua planted in bamboo forest and field in Sanzhulun Mountain area of Jin-gan County,Jiangxi Province were taken as the research object.Using the constant pressure steam nine-steam-nine-bask processing method,the contents of extracts,polysaccharides,total flavonoids,total saponins and total phenols were measured.The variation law of the content of each chemical component was analyzed,and the quality of each sample was evaluated comprehensively by member-ship function method.The results showed that during the processing process,the content of extracts was higher than the 45%specified in pharmacopoeia;with the increase of processing times,the content of polysaccharide decreased,and the content was lower than the index specified in pharmacopoeia;the content of total flavonoids showed an increasing trend;the content of total saponins showed a fluctuating trend;the total phenol content showed a decreasing trend,with the highest content in fresh Polygonatum cyrtonema Hua;the appearance character changes of Polygonatum cyrtonema Hua were consistent,with the increase of processing times,the color gradually became darker and finally became black.By calculating the membership function values of each component and conducting comprehensive ranking,it was found that the imitation of wild Polygonatum cyrtonema Hua under bamboo forest was better than that under field cultivation.At the same time,it was found that the comprehensive ranking of the seventh processing of forest plantings was higher than that of other processing times,and the comprehensive ranking of the fourth processing of field plantings was higher than that of other processing times.
