Abstract

The invention relates to a preparation method of a Liuwei Dihuang oral liquid treated by pepsin. The preparation method comprises the following steps: (1) crushing raw materials of Liuwei Dihuang pill to obtain raw material powder, adding water and mixing uniformly to prepare raw material slurry; and (2) adding acid into the raw material slurry to adjust pH value, adding pepsin, treating and adjusting pH value by alkali to prepare the Liuwei Dihuang oral liquid treated by pepsin. According to the invention, raw materials of traditional Liuwei Dihuang pill are decomposed and treated by pepsin to obtain a Liuwei Dihuang oral liquid treated by pepsin of which side effect is relatively low. The Liuwei Dihuang oral liquid treated by pepsin has an agreeable sour-sweet taste. According to practical application, therapeutic effect of Liuwei Dihuang pill can be achieved and side effects of stomach cold and digestion obstacle can be greatly reduced by long-term taking of the Liuwei Dihuang oral liquid treated by pepsin.

Description

A kind of preparation method of Liuweidihuang Oral Liquid of pepsin

Technical field

The present invention relates to a kind of preparation method of Liuweidihuang Oral Liquid of pepsin, particularly a kind of method utilizing the classical LIUWEI DIHUANG WAN prescription of biotechnology process, belongs to biomedicine technical field.

Background technology

LIUWEI DIHUANG WAN stems from the JINGUI SHENQI WAN in the large physician's Zhang Zhongjing " Medical Treasures of the Golden Chamber " of the Eastern Han Dynasty, also be " shenqi pill ", " Rehmanniae Bolus of Eight Ingredients ", be originally eight taste Chinese crude drugs, afterwards to the Northern Song Dynasty, by national imperial physician assistant officer Qian Yi, former side is deducted Cortex Cinnamomi, Radix Aconiti Lateralis Preparata two taste Chinese medicine, defines by Radix Rehmanniae Preparata, Fructus Corni, Rhizoma Dioscoreae (three taste tonics), Poria, Rhizoma Alismatis, the LIUWEI DIHUANG WAN of Cortex Moutan (three taste cathartics) ingenious compatibility; Three mend and three to rush down, and mend and not dry.LIUWEI DIHUANG WAN, from Song dynasty Cheng Fang, continues more than 1000 year till now always, lasting through successive dynasties doctor and undergoing of patient, can be described as " volt cattle prescription changes, and within thousand, medicine does not wane ".

But because LIUWEI DIHUANG WAN belongs to sweet warm nature, the relatively medicine of nourishing YIN, cure mainly deficiency of the kidney yin, in its formula, cloudy soft medicine is more, so sometimes can antidigestive side effect after eating, therefore not only spleen and stomach function is weak, dyspepsia person is careful eats, and long-term taking can cause the malaise symptoms such as abdominal distention, loose stool, inappetence.

Chinese patent literature CN102920882A(application number 201110338130.2) disclose a kind of preparation method of concentrated pill of six ingredients with rehmannia, it is characterized in that comprising the steps: that (1) takes raw material by following weight portion: Radix Rehmanniae Preparata 120 parts, wine Fructus Corni 60 parts, Cortex Moutan 45 parts, Rhizoma Dioscoreae 60 parts, 45 parts, Poria, Rhizoma Alismatis 45 parts; (2) Cortex Moutan is dropped in extraction pot, extract paeonol with steam distillation; First open condensed water, open straight-through steam valve again, steam regulation pressure is at 0.1Mpa ~ 0.3Mpa, in tank, temperature remains on 100 ~ 110 DEG C, and pressure is ﹤ 0.05Mpa, and regulating condensate flow to make material pipe above crystallizer flow out paeonol distillate temperature is 40 DEG C ~ 60 DEG C, collect paeonol distillate, cold preservation, crystallize, collects paeonol crystal; (3) get Radix Rehmanniae Preparata 120 parts, wine Fructus Corni 20 parts, 45 parts, Poria, Rhizoma Alismatis 45 parts, adopt dynamic extraction mode, decoct with water 1 ~ 3 time, each 1 ~ 1.5 hour, decocting liquid filters, and merges, and is concentrated into the thick paste (55 ~ 60 DEG C of mother-in-law prunus mume (sieb.) sieb.et zucc. proportion measurements) that proportion is 1.35 ~ 1.40; (4) after Rhizoma Dioscoreae 60 parts and wine Fructus Corni 40 parts pulverized 80 mesh sieves, mixing, obtains fine powder, obtains sterilized powder after moist heat sterilization; (5) by the paeonol crystal of step (2) (3) (4) gained, thick paste, fine powder mixing, add pharmaceutically acceptable adjuvant, obtained wet ball, dry, polishing, to obtain final product.

Although the active ingredient in LIUWEI DIHUANG WAN can be extracted concentrated obtained concentrated pill of six ingredients with rehmannia by above-mentioned patent, the antidigestive side effect of LIUWEI DIHUANG WAN does not weaken.
