摘 要 目的 优化龙眼核标准汤剂的提取工艺。方法 以加水量、提取时间、提取次数为影响因素,出膏率、没食子酸含量、柯里
拉京含量、鞣花酸含量、1,1-二苯基-2-苦基肼(DPPH)自由基半数清除浓度(IC50 )和2,2′-联氮双(3-乙基苯并噻唑啉-6-磺酸)二胺
盐(ABTS)自由基IC50为评价指标,运用层次分析法(AHP)、基于指标相关性的权重赋权系数(CRITIC)法、AHP-CRITIC法计算各
指标权重,结合单因素实验和正交实验优化龙眼核标准汤剂提取工艺,并进行验证。结果 根据AHP-CRITIC法确定上述各指标
的权重依次为 9.224%、11.784%、19.320%、11.206%、20.597%、27.869%。龙眼核标准汤剂的最佳提取工艺为第 1 次提取加 14 倍
水,提取 30 min;第 2、3 次提取均加 12 倍水,提取 20 min。3 次验证实验所得综合得分平均值为 97.96 分,RSD 为 0.97%(n=3)。
结论 优选的工艺稳定可行,可为龙眼核标准汤剂的进一步开发和利用提供实验依据。

ABSTRACT OBJECTIVE To optimize the extraction process of standard decoction of Longan seed. METHODS The amount of
water added, extraction time and extraction times as the influencing factors, using the extract yield, gallic acid content, corilagin
content, ellagic acid content, half clearance concentration (IC50 ) of 1,1-diphenyl-2-picryl-hydrazyl (DPPH) free radical and IC50 of
2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) ammonium salt (ABTS) free radical as the evaluation indexes, the analytic
hierarchy process (AHP), criteria importarue though inter-criteria correlation (CRITIC) and AHP-CRITIC method were used to
calculate the weight values of each index; the extraction process of Longan seed standard decoction was optimized by single factor
test combined with orthogonal experiment; validation test was also performed. RESULTS According to the AHP-CRITIC method,
the weights of the above indicators were determined to be 9.224%, 11.784%, 19.320%, 11.206%, 20.597%, 27.869%,
respectively. The best process of standard decoction of longan seed was to add 14 times water for the first extraction and extract for
30 minutes; and 12 times water for the second and third extractions, and extract for 20 minutes. Average comprehensive score of
the 3 times validation experiments was 97.96 and the RSD was 0.97% (n=3). CONCLUSIONS The process is simple to operate,
stable and feasible, which can provide a experimental basis for the further development and utilization of standard decoction of
longan seed.
