目的探讨不同煎药方法对水溶性浸出物浸出率及药效的影响。方法选择2015年6月至2016年11月需煎服中药的患者72例,根据煎药方式分为两组,每组36例。观察组采用现代煎药机制药,对照组予以传统煎药方法制药。对比两组临床疗效、水溶性浸出物浸出率及煎药情况。结果对照组水溶性浸出物浸出率高于观察组,差异有统计学意义(P<0.05);观察组煎煮时间[(4.7±1.3)min]、加水量[(600.4±11.0)ml]、药物成本[(4.8±0.9)元]低于对照组[(25.6±2.7)min、(1000.5±13.1)ml、(12.3±2.9)元],而服药总次数[(15.6±1.8)次]高于对照组[(12.4±2.4)次],差异有统计学意义(P<0.05)。结论与传统煎药法相比,现代煎药机在减少煎煮时间、加水量、药物成本方面效果更优,但水溶性浸出物浸出率欠佳。
Objective To investigate the effects of different decoction methods on the leaching rate and efficacy of water-soluble extract. Methods Seventy-two patients requiring decoction of traditional Chinese medicine from June 2015 to November 2016 were divided into two groups according to the decoction method, with 36 cases in each group. Observation group using modern decoction machine medicine, the control group to traditional decoction method of medicine. The clinical efficacy, the leaching rate of water-soluble extract and the decoction were compared between the two groups. Results The leaching rate of water-soluble extract in the control group was significantly higher than that in the observation group (P <0.05). The boiling time in the observation group [(4.7 ± 1.3) min] and the amount of water [600.4 ± 11.0 ml] The cost of medication [(4.8 ± 0.9) yuan] was lower than that in the control group [(25.6 ± 2.7) min, (1000.5 ± 13.1) ml, (12.3 ± 2.9) yuan] In the control group [(12.4 ± 2.4) times], the difference was statistically significant (P <0.05). Conclusion Compared with the traditional decoction method, modern decoction machine is more effective in reducing decocting time, adding water and drug cost, but the leaching rate of water-soluble extract is not good.
