目的 研究胃肠安丸抗炎活性，初步分析其活性成分。方法 采用HPLC法对胃肠安丸甲醇提取物进行成分分析；采用二甲苯致小鼠耳肿胀、角叉菜胶致大鼠足趾肿胀、冰醋酸致小鼠毛细血管通透性增加3种急性炎症模型以及大鼠棉球肉芽肿慢性炎症模型，研究胃肠安丸甲醇提取物对急慢性炎症的作用。结果 胃肠安丸甲醇提取物中有12个主要成分，分别为来源于木香中的木香烃内酯、去氢木香内酯，来源于厚朴中的厚朴酚、和厚朴酚，来源于枳壳中的柚皮苷、橙皮苷、新橙皮苷，来源于大黄中的芦荟大黄素、大黄酸、大黄素、大黄酚、大黄素甲醚。胃肠安丸甲醇提取物800 mg/kg时，对小鼠耳肿胀的抑制率达39.46%，对冰醋酸所致小鼠毛细血管通透性增加的抑制率为35.37%；并对角叉菜胶致炎大鼠足趾致炎后1 h显现抗炎活性；对大鼠棉球肉芽肿显示抑制活性。结论 胃肠安丸对动物急慢性炎症均具有较好的抗炎作用。

Objective To study the active constituents in the methanol extract of Weichang’an Pill (MEWP) and their anti-inflammatory activity. Methods The HPLC method was used to anylyze the constituents in MEWP. The anti-inflammatory effects of MEWP were observed on the acute anti-inflammatory models of xylene-induced ear edema, carrageenan-induced paw edema, and acetic acid-induced vascular permeability; Meanwhile the chronic anti-inflammatory model of granuloma was induced by cotton pellet implantation. Results Twelve active constituents in MEWP were analyzed, including costunolide and dehydro-α- curcumene from Aucklandiae Radix; naringin, hesperedin, and neohesperedin from Aurantii Fructus; magnolol and honokiol from Magnoliae Officinalis Cortex; aloe-emodin, rhein, emodin, chrysophanol, and physcion from Rhei. Radix et Rhizoma. At the dose of 800 mg/kg, the MEWP showed the inhibitory rate of 39.46% on the ear edema and 35.37% on the increasing of capillary permeability induced by acetic acid in mice. It could decrease the paw edema caused by carrageenan after 1 h and inhibit the granuloma induced by cotton pellet implantation. Conclusion The MEWP could antagonize the reaction of inflammation.
