目的
2
优化盐车前子的炮制工艺,明确其工艺参数,并结合药效学研究对所得炮制工艺进行验证,为盐车前子的规范化生产和质量控制提供实验依据。
方法
2
以3个指标成分(京尼平苷酸、毛蕊花糖苷、异毛蕊花糖苷)质量分数、外观性状评分和干膏得率的综合评分为指标,采用层次分析法(AHP)-指标相关性的指标权重确定方法(CRITIC)混合加权法确定各评价指标的权重系数,在单因素试验基础上,利用响应面法考察炒制温度、炒制时间、加盐量和加水量对盐车前子炮制工艺的影响,并通过利尿试验对盐车前子炮制工艺进行验证,选择呋塞米片为阳性药(给药剂量0.01 g·kg
-1
)。
结果
2
AHP-CRITIC混合加权法确定京尼平苷酸质量分数、毛蕊花糖苷质量分数、外观性状评分、异毛蕊花糖苷质量分数、干膏得率的权重系数分别为0.319,0.193,0.207,0.273,0.008。最佳盐炙工艺参数为每100 g车前子生品于150~180 ℃文火炒制10 min,均匀喷淋盐水(食盐2 g加水20 mL使溶解)20 mL,于150~180 ℃炒制15 min,取出,放凉。与空白组比较,车前子组和盐车前子组均能增加尿量分泌量(
P
<
0.01),但盐车前子组大鼠尿液电解质Na
+
排泄较车前子组显著升高(
P
<
0.05)。
结论
2
优选的炮制工艺简单可行,可为规范盐车前子饮片的工业化生产提供参考。同时,结合盐车前子内在质量和外观性状,并利用药效学试验进行验证,所得结果更加合理可信,可用于该饮片的质量控制。
Objective
2
To optimize the processing technology of salt-processed products of Plantaginis Semen with the specific process parameters
and verify the obtained processing technology by pharmacodynamic research
so as to provide experimental basis for the standardized production and quality control of this decoction pieces.
Method
2
Taking composite score of appearance character score
dry extract yield and contents of three components (geniposidic acid
acteoside and isoacteoside) as index
the analytic hierarchy process (AHP)-criteria importance through intercrieria correlation (CRITIC) mixed weighting method was used to determine the weight coefficient of each index. Based on single factor tests
the response surface method was used to investigate the effects of frying time
frying temperature
salt amount and water amount on the processing technology of salt-processed products of Plantaginis Semen
and the processing technology was verified by diuretic experiment with furosemide tablets as the positive drug (administration dose of 0.01 g·kg
-1
).
Result
2
The weight coefficients of geniposidic acid content
acteoside content
appearance character score
isoacteoside content and dry extract yield were 0.319
0.193
0.207
0.273 and 0.008
respectively. The optimal process parameters were as following:fried at 150-180 ℃ for 10 min (obtained from the single factor tests)
100 g of Plantaginis Semen sprayed evenly with 2 g of salt (2 g of salt dissolved in 20 mL of water)
and fried at 150-180 ℃ for 15 min. Compared with the blank group
both of the raw products group and the salt-processed products group could significantly increase the secretion of urine volume (
P
<
0.01)
but the excretion of Na
+
in the urine of rats in the salt-processed products group was significantly higher than that in the raw products group (
P
<
0.05).
Conclusion
2
The optimized processing technology is simple and feasible
which can provide reference for standardizing the industrial production of salt-processed products of Plantaginis Semen. At the same time
combined with inherent quality and appearance of the salt-processed products
and verified by pharmacodynamic test
the obtained results are reasonable and reliable
which can be used for quality control of this decoction pieces.
