Problems solved by technology

[0005] In recent years, the research on dog spine has gradually increased. Pharmacological studies have shown that dog spine and its extraction parts have a variety of biological activities, mainly including prevention and treatment of osteoporosis, inhibition of platelet aggregation, hemostasis and analgesia, antibacterial, anti-inflammatory, anti-rheumatism , liver protection, anti-oxidation and anti-cancer effects, but there is still a lack of research on the mechanism of action, and the research on the basis of its pharmacodynamics is not deep enough, and the content of various components is not clear
So far, there are no research reports on the extraction and preparation of protocatechuic acid, protocatechualdehyde, 5-HMF (5-hydroxymethylfurfural) and kojic acid, which are the effective parts of dog spines

Abstract

The invention provides prepared cibotium barometz tuber effective parts and a preparation method thereof. The preparation method comprises the following steps of taking 40g of prepared cibotium barometz tuber medicinal material fine powder, adding 800mL of methanol-water in the volume ratio being 70 to 30, performing reflux extraction twice, wherein the reflux extraction time each time is 2h, performing filtration, and taking filtrate for standby application; additionally taking 3g of activated DM2 type resins, and performing loading into a column; taking 15mL of a cibotium barometz tuber extracting solution, conveying samples to a detection instrument, performing adsorption for 4h, performing eluting with 45mL of methanol-water in the volume ratio being 20 to 80, collecting an eluent, andperforming evaporation to dryness so as to obtain the prepared cibotium barometz tuber effective parts. According to the cibotium barometz tuber effective parts prepared by the method, the kojic acidcontent in percentage by mass is more than 0.4%, the 5-HMF content in percentage by mass is more than 13.5%, the protocatechuic acid content in percentage by mass is more than 0.6%, and the protocatechuic aldehyde content in percentage by mass is more than 0.5%. The preparation method is simple and environmental-friendly and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to an effective part for making dog spines and a preparation method thereof, belonging to the technical field of medicine. Background technique [0002] Dog spine, the name of Chinese medicine. It is the dried rhizome of Cibotium barometz (L.) J.Sm. Excavated in autumn and winter, remove the silt, and dry; or remove hard roots, petioles, and golden fluff, cut into thick slices, and dry to become "raw dog ridge slices"; steam and dry until 60% to 70% dry, and cut into thick slices Slices, dried, are "cooked dog ridge slices". "Chinese Pharmacopoeia" over the years has recorded it as a commonly used traditional Chinese medicine, which has the effects of dispelling rheumatism, nourishing the liver and kidney, and strengthening the waist and knees. Aggregation, anti-inflammatory, anti-rheumatic, liver protection, anti-oxidation and anti-cancer pharmacological activities. Dog ridge is mainly distributed in Zhejiang, Jiangxi, Fujian...
