Abstract

The invention relates to a method for preparing a nine-flavor notopterygium dropping pill. The method comprises the following steps: (1) crushing the prescriptions of the nine-flavor notopterygium dropping pill to medicinal material crude powder; (2) mixing notopterygium root, divaricate saposhnikovia root, rhizoma atractylodis, asarum and ligusticum wallichii, and distilling to obtain volatile oil and a distilled solution, respectively; (3) preparing pure volatile oil; (4) preparing a volatile oil absolute ethyl alcohol solution; (5) adding distilled water into beta-cyclodextrin to prepare a saturated solution, and then adding the volatile oil absolute ethyl alcohol solution to prepare a volatile oil clathrate compound; (6) mixing radix angelicae with scutellaria baicalensis, and performing alcohol extraction to obtain a filtrate A; (7) performing vacuum concentrating on the filtrate A to obtain an extract A; (8) mixing licorice with radix rehmanniae, and adding water for decoration to obtain a filtrate B; (9) mixing the distilled solution with the filtrate B, and performing vacuum concentration and alcohol precipitation filtration to obtain a filtrate C; (10) performing vacuum concentrating on the filtrate C to obtain an extract C; (11) fusing polyethylene glycol, adding the volatile oil clathrate compound, the extract A and the extract to prepare dropping pills. The method provided by the invention is stable in quality and high in bioavailability.

Description

technical field [0001] The invention relates to a preparation method of dripping pills, in particular to a preparation method of Jiuwei notopterygium dripping pills. Background technique [0002] The prescription of Jiuwei notopterygium is derived from Zhang Yuanyuan's "This matter is difficult to know", mainly composed of notopterygium 150g, fangfeng 150g, atractylodes 150g, asarum 50g, chuanxiong 100g, angelica dahurica 100g, scutellaria baicalensis 100g, licorice 100g, rehmannia glutinosa 100g, mainly for exogenous wind-cold-dampness Evil, combined with interior heat syndrome, manifested in aversion to cold and fever, no sweat on the skin surface, headache and numbness, sore limbs, bitter mouth and slightly thirsty, white or yellowish tongue coating, and floating pulse. At present, the common Jiuwei notopterygium preparations in clinical practice include pills, granules, oral liquids, tablets, soft capsules, sprays, etc. [0003] Chinese patent ZL 200510057076.9, the pre...
