摘要:本文以虎杖苷、川續斷皂苷Ⅵ的含量和提取物得率為指標,在對提取條件進行單因素考察的基礎上,采用正交試驗法優化提取工藝,以確定愈骨散的最佳提取條件。試驗結果表明,料液比對提取影響最大,最佳提取條件為:提取溶劑為75%乙醇、料液比1∶10、提取時間2h,提取2次。在最優條件下所得提取物得率為1625%,虎杖苷含量為7401mg,川續斷皂苷Ⅵ含量為1472mg。該提取方法可為愈骨散的進一步研究和開發提供支撐。

Abstract:This study is aimed to establish the optimal extraction procedure of YugusanThe contents of polydatin,Asperosaponin VI and extraction rates were used as comprehensive evaluation indexesBased on the results of the single factor experiment,the extraction conditions of Yugusan were further optimized by orthogonal designThe extracting ratio of solidliquid ratio had main effects on the comprehensive extraction procedureThe optimal procedure was obtained as follows:75% ethanol,solidliquid ratio 1∶10,extraction time 2h for 2 timesUnder the optimal conditions it could reach the content of polydatin and Asperosaponin VI 7400mg,14720mg separately and extraction rates were 1625%This extraction procedure could be used for the further research and development of Yugusan

愈骨散為我國民間用于治療骨折的傳統驗方,在民間有較長的應用歷史,具有良好的療效。該驗方主要由虎杖(Polygonum cuspidatum Siebet Zucc)、川續斷(Dipsacus asperoides CYCheng et TMAi)、補骨脂(Psoralea corylifolia L)等8味中藥材組成,為外用藥,其中君藥為虎杖、川續斷等,在治療跌打損傷,續筋接骨方面具有一定的療效。
愈骨散傳統的使用方法是直接將藥材粉碎成粉末后加以適當的輔料調敷于患處。該法存在著療效不穩定、使用不便、對皮膚具有刺激性、且會弄臟衣服等缺點,嚴重影響了該驗方的推廣使用。本文擬在原有驗方基礎上,將其開發為安全有效、質量可控、使用方便、刺激性小的現代制劑貼膏劑[1]。
將愈骨散驗方制備成貼膏劑前,需對其提取工藝進行研究[2]。以虎杖苷、川續斷皂苷Ⅵ的含量和提取物得率為指標,考察提取溶劑、提取溶劑濃度、提取時間、提取料液比、提取方法等因素,并通過正交試驗確定最佳提取工藝[3],旨在為后期制劑的開發利用打下基礎。……
