To establish a method for quick finding the absorption ingredients of Wuzhuyu decoction in order to select the index to control its quality.
The absorption of three concentration of Wuzhuyu decotion was investigated with the in vitro-everted intestinal sac model. The intestinal bag fluid of jejunum and ileum were collected in different time and the eight ingredients, which were evodiamine (Ev), rutaecarpine (Ru), limonin (Li), ginsenoside-Rb1, -Rg1, -Re (Rb1, Rg1, Re), isorhamnetin-3-O-beta-D-glucosyl(6''-->1'")-alpha-L-rhamnoside (Irs)and 6-gingerol (6-Gi), were detected by HPLC as the represent constituents in samples.
Eight ingredients except Ru in samples could be detected, but Ev could not be detected in high concentration samples. The ratios between absorption ingredients were different from in Wuzhuyu decotion.
The in vitro-everted intestinal sac canc absorb the ingredients of Wuzhuyu decotion selectivity. Compare with the ileum, the jejunum can provide the more absorption information and faster, the best test time is 60-90 min.
建立快速筛选吴茱萸汤吸收成分的方法，以选择其质量控制指标。
采用体外翻肠囊模型考察吴茱萸汤3种浓度的吸收情况。于不同时间收集空肠和回肠肠囊液，采用高效液相色谱法检测吴茱萸次碱（Ev）、吴茱萸碱（Ru）、柠檬苦素（Li）、人参皂苷-Rb1、-Rg1、-Re（Rb1、Rg1、Re）、异鼠李素-3-O-β-D-葡萄糖基（6''→1'")-α-L-鼠李糖苷（Irs）和6-姜辣素（6-Gi）这8种成分，作为样品中的代表性成分。
样品中除Ru外的8种成分均可被检测到，但高浓度样品中未检测到Ev。吸收成分之间的比例与吴茱萸汤中的不同。
体外翻肠囊可选择性吸收吴茱萸汤中的成分。与回肠相比，空肠能提供更多、更快的吸收信息，最佳检测时间为60 - 90分钟。
