Objective:

To determine the index weight coefficient, optimize the ultrasonic extraction process of flavonoids in Scutellaria baicalensis Georgi and analyze its anti-inflammatory activity in vitro.

Methods:

On the basis of single factor test, ethanol concentration (A), ultrasonic time (B), ultrasonic temperature (C) and material-to-liquid ratio (D) were selected as the investigation factors. Taking baicalin, wogonin, baicalein and wogonin as the inspection indicators, the AHP-CRITIC mixed weighting method was used to determine the weight coefficients of each index, multivariate binomial was fitted combined with the response surface method, a three-dimensional graph was drawn, and the best extraction process was chosen. At the same time, the MTT method and Griess method were used to evaluate the in vitro anti-inflammatory activity of the ultrasonic extraction of Scutellaria baicalensis Georgi.

Results:

The optimal extraction conditions for flavonoids in Scutellaria baicalensis Georgi were as follows: ethanol concentration of 62.73%, ultrasonic time of 32.23 min, ultrasonic temperature of 51.15 ℃, and material-to-liquid ratio of 1∶16.12. The average AHP-CRITIC comprehensive score of three batches of verification samples was 85.28, and the RSD with the theoretical prediction value was 0.50%. The results of MTT method showed that when the concentration of Scutellaria baicalensis Georgi extraction was greater than 400 μg·mL-1, the cell viability decreased significantly (P<0.05, P<0.01). When the concentration of Scutellaria baicalensis Georgi extraction was 50~350 μg·mL-1, the release of NO in RAW264.7 inflammatory cells was significantly inhibited (P<0.05, P<0.01).

Conclusion:

The method is stable and reliable and can be used for the extraction of flavonoids from Scutellaria baicalensis Georgi, and the ultrasonic extract has strong anti-inflammatory activity in vitro.

目的:

确定指标权重,优化黄芩中黄酮类成分的超声提取工艺,并分析其体外抗炎活性。

方法:

在单因素实验基础上,选择乙醇浓度(A)、超声时间(B)、超声温度(C)及料液比(D)为考察因素,以黄芩苷、汉黄芩苷、黄芩素及汉黄芩素为考察指标,采用层次分析-指标相关性赋权系数法(AHP-CRITIC)确定各指标权重系数,结合响应面法拟合多元二项式,绘制三维图,选择最佳提取工艺;同时利用MTT法和Griess法评估黄芩提取物的体外抗炎活性。

结果:

黄芩中黄酮类成分的最佳提取条件为:乙醇浓度62.73%、超声时间32.23 min、超声温度51.15 ℃、料液比1∶16.12。3批验证样品的AHP-CRITIC综合评分平均值为85.28,与理论预测值的RSD为0.50%。MTT法结果表明黄芩提取物浓度>400 μg·mL-1时细胞活力显著下降(P<0.05,P<0.01);黄芩提取物浓度为50~350 μg·mL-1时,可显著抑制RAW264.7炎性细胞一氧化氮(NO)的释放(P<0.05,P<0.01)。

结论:

该方法稳定可靠,可用于黄芩中黄酮类成分的提取,其超声提取物具有一定的体外抗炎活性。

目的:

确定指标权重,优化黄芩中黄酮类成分的超声提取工艺,并分析其体外抗炎活性。

方法:

在单因素实验基础上,选择乙醇浓度(A)、超声时间(B)、超声温度(C)及料液比(D)为考察因素,以黄芩苷、汉黄芩苷、黄芩素及汉黄芩素为考察指标,采用层次分析-指标相关性赋权系数法(AHP-CRITIC)确定各指标权重系数,结合响应面法拟合多元二项式,绘制三维图,选择最佳提取工艺;同时利用MTT法和Griess法评估黄芩提取物的体外抗炎活性。

结果:

黄芩中黄酮类成分的最佳提取条件为:乙醇浓度62.73%、超声时间32.23 min、超声温度51.15 ℃、料液比1∶16.12。3批验证样品的AHP-CRITIC综合评分平均值为85.28,与理论预测值的RSD为0.50%。MTT法结果表明黄芩提取物浓度>400 μg·mL-1时细胞活力显著下降(P<0.05,P<0.01);黄芩提取物浓度为50~350 μg·mL-1时,可显著抑制RAW264.7炎性细胞一氧化氮(NO)的释放(P<0.05,P<0.01)。

结论:

该方法稳定可靠,可用于黄芩中黄酮类成分的提取,其超声提取物具有一定的体外抗炎活性。

Objective:

To determine the index weight coefficient, optimize the ultrasonic extraction process of flavonoids in Scutellaria baicalensis Georgi and analyze its anti-inflammatory activity in vitro.

Methods:

On the basis of single factor test, ethanol concentration (A), ultrasonic time (B), ultrasonic temperature (C) and material-to-liquid ratio (D) were selected as the investigation factors. Taking baicalin, wogonin, baicalein and wogonin as the inspection indicators, the AHP-CRITIC mixed weighting method was used to determine the weight coefficients of each index, multivariate binomial was fitted combined with the response surface method, a three-dimensional graph was drawn, and the best extraction process was chosen. At the same time, the MTT method and Griess method were used to evaluate the in vitro anti-inflammatory activity of the ultrasonic extraction of Scutellaria baicalensis Georgi.

Results:

The optimal extraction conditions for flavonoids in Scutellaria baicalensis Georgi were as follows: ethanol concentration of 62.73%, ultrasonic time of 32.23 min, ultrasonic temperature of 51.15 ℃, and material-to-liquid ratio of 1∶16.12. The average AHP-CRITIC comprehensive score of three batches of verification samples was 85.28, and the RSD with the theoretical prediction value was 0.50%. The results of MTT method showed that when the concentration of Scutellaria baicalensis Georgi extraction was greater than 400 μg·mL-1, the cell viability decreased significantly (P<0.05, P<0.01). When the concentration of Scutellaria baicalensis Georgi extraction was 50~350 μg·mL-1, the release of NO in RAW264.7 inflammatory cells was significantly inhibited (P<0.05, P<0.01).

Conclusion:

The method is stable and reliable and can be used for the extraction of flavonoids from Scutellaria baicalensis Georgi, and the ultrasonic extract has strong anti-inflammatory activity in vitro.
