基于纹党参鲜药材的产地加工炮制一体化技术研究
摘要:目的 研究不同干燥过程对纹党参饮片有效成分的影响,确定最佳的基于纹党参鲜药材的产地初加工与炮制一体化工艺。方法 对采收期的纹党参鲜药材分别采用3种加工炮制方法:①烘箱80 ℃烘至含水量为药材原始含水量不同百分比(30%~100%)时,分别取出切片,50 ℃烘干,制得8个饮片样品(XⅠYP1~8)。②鲜纹党参直接在不同温度(50~120 ℃)分别烘至含水量为药材原始含水量的50%时,取出切片,50 ℃烘干,制得8个饮片样品(XⅡYP1~8)。③纹党参干药材,闷润,切片,自然晾干,制得传统饮片。采用HPLC测定各样品中党参炔苷和苍术内酯Ⅲ,苯酚-硫酸法和比色法分别测定多糖及总黄酮含量,并同时测定醇浸出物、水浸出物含量。结果 饮片XⅠYP3的醇浸出物(55.36%)、水浸出物(54.91%)和苍术内酯Ⅲ(10.95 ?g/g)含量均高于其他饮片。结论 优选的工艺为:80 ℃烘至含水量50%,切片,干燥。获得的一体化加工工艺较传统方法省时、省力。制得的饮片活性成分含量高。

Abstract: Objective To study the effects of different drying processes on the effective constituents in Wen Codonopsis pilosula (WPP) Decoction Pieces; To develop the optimized producing and preparing integration process based on fresh WPP. Methods Fresh WPP in harvest period was prepared respectively as follows: ① Fresh WPP was dried to different percentage (30%–100%) of original moisture contents of crude drugs at 80 ℃ in oven, then sliced and dried at 50 ℃ to obtain eight decoction pieces of WPP (XⅠYP1–8). ② The fresh WPP was baked to 50% of water content of crude drug under different temperatures (50–120 ℃), respectively, then sliced and dried at 50 ℃ to obtain eight decoction pieces of WPP (XⅡYP1–8). ③ Dried WPP was moistened, sliced and naturally dried, then were renamed as traditional decoction pieces. The contents of lobetyolin and atractylenolide Ⅲ was determined by HPLC. The phenol-sulfuric acid and colorimetric method were applied respectively to detect contents of polysaccharide and total flavonoids. The contents of aqueous and alcoholic extracts were determined simultaneously. Results The contents of alcoholic extracts (55.36%), aqueous extracts (54.91%) and atractylenolide Ⅲ (10.95 ?g/g) in XⅠYP3 pieces were higher than other decoction pieces. Conclusion The optimized process was that fresh WPP was baked to water content of 50% at 80 ℃, then sliced and dried. Compared with conventional preparing methods,
