Description
Technical field
The present invention relates to derive from the preparation method of the medicine of plant material, be specifically related to a kind of Herba Andrographis extract and preparation method thereof.
Background technology
The Herba Andrographis medical material is acanthaceous plant Herba Andrographis
Andrographis paniculata(Burm.f.) herb of Nees has the effect of heat-clearing and toxic substances removing, removing heat from blood detumescence, and it is wide to distribute in Guangdong, and cultivation history is long.It is the raw medicinal material of the multiple famous-brand and high-quality Chinese patent medicines such as CHUANXINLIAN ZHUSHEYE, Chuanhuning preparation, andrographis tablet, XIAOYAN LIDAN PIAN, FUFANG CHUANXINLIAN PIAN.Its active component is the compositions such as andrographolide, outside this active component, also has lower other type chemical constituents such as pigment of many content.Andrographolide isoreactivity composition is subjected to thermally labile, is easy to decompose, and long-time heating can cause the structural deterioration of lactonic ring.In the preparation process of Herba Andrographis, andrographolide is in the technical process of Herba Andrographis extracting solution through concentrated and drying, and the loss rate of andrographolide and dehydrorographolide is large.In addition, other one-tenth in Herba Andrographis toxic and side effects [Academy of Military Medicine, PLA that impurity usually causes Herba Andrographis that grades, 2010, the doctorate paper, " the LIANBIZHI ZHUSHEYE safety revalues research "], Optimization Technology, the impurity component of removing tool invalid components or toxic side effect, the heat loss that reduce to extract andrographolide constituents in the concentration process are that the important topic that solves is badly in need of in the famous-brand and high-quality Chinese patent medicine manufacturer take Herba Andrographis as raw material always." creat formulation such as andrographis tablet, the XIAOYAN LIDAN PIAN etc. of Chinese pharmacopoeia (version in 2010) record, the extraction process of its Herba Andrographis raw medicinal material all is to get the alcohol extract of Herba Andrographis, adds other supplementary materials after concentrated, the drying and makes.In the production technology of its extract, the loss of andrographolide is larger, simultaneously, the active component andrographolide is not carried out purification, and the content of other compositions such as Herba Andrographis pigment is higher.
Bibliographical information is arranged to the research of the extraction process of Herba Andrographis.Such as " extraction process of creat extract ", Chinese herbal medicine 2002,6 (3): 7-9.Disclose and Herba Andrographis is put forward acid precipitation technique with alkali extracted, cost is low, the extraction efficiency of andrographolide is high, but its extraction process is complicated, easily hydrolysis in the concentration process, restive in the production, be not suitable for industrialized mass production, moreover how paper does not mention the purification andrographolide, remove the impurity components such as Herba Andrographis pigment, do not mention the concentrated, dry of extracting solution and the technology and the method that prepare its dry extract.
In addition, document " andrographolide extraction process amelioration " Chinese medicine information 2002,19(3): 50-52, mentioned the Herba Andrographis extracting solution with remove impurity with active carbon, the chloroform dissolving, the technique of acetone recrystallization is extracted the andrographolide composition, the purpose of this technique is to extract this monomer component of andrographolide, use a large amount of organic solvents in its technical process, to production safety require highly, be not suitable for equally industrialized large production.
In the Study on extraction of Herba Andrographis, the described technique of Chinese Pharmacopoeia is simple, behind 85% ethanol extraction, and extracting solution Recycled ethanol, dry getting final product.But in the present suitability for industrialized production, the concentrated drying process that all adopts single-action or the two hot concentration technologies of effect and oven dry, thereby, by its effective ingredient in the andrographis tablet of pharmacopeia explained hereafter--the total andrographolides composition has lost totally (" changes of contents of dehydrorographolide in the andrographis tablet production process " in process of production, CHINA JOURNAL OF CHINESE MATERIA MEDICA, 2002,12,36-38), this shows, this simple production Technology is not only removed impurity component, also be difficult to keep the effective ingredient in the Herba Andrographis, seriously influence the quality of creat formulation, for this reason, how further to have studied the yield of Effective Raise andrographolide isoreactivity composition, the large process for producing technology of removing to greatest extent the impurity components such as pigment has very important meaning for the quality and the curative effect that guarantee creat formulation.
