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.MethodsFresh 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 atractylenolideⅢ 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 atractylenolideⅢ (10.95 μg/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,the integration process was time-saving and effort-saving. Meanwhile, the prepared pieces have higher content of active ingredients.
