A preparation method of the triterpenoid A2 comprises the following steps: drying and crushing the oriental oriental waterplantain rhizome, dipping the oriental oriental waterplantain rhizome in acetone at room temperature, crushing and extracting, filtering, merging filtrate, and concentrating under reduced pressure to obtain an extract; sequentially extracting the extract with petroleum ether, dichloromethane, ethyl acetate and n-butyl alcohol with the same amount, concentrating and drying to obtain a petroleum ether part, a dichloromethane part, an ethyl acetate part, an n-butyl alcohol part and a water part; dissolving the dichloromethane part with methanol, stirring silica gel, packing and eluting for four times to obtain a target fraction; and loading the target fractions on a chromatographic column, collecting fractions within the retention time, concentrating and drying to obtain the target fractions. The raw materials are rich, a unique preparation method is adopted, and the compound A2 can improve airway inflammation and airway hyperresponsiveness of OVA-induced allergic asthma, can be used for preparing drugs for treating allergic asthma, develops the medicinal value and economic value of oriental rhizoma alismatis, and has huge economic and social benefits.

A method for extracting two tocopherol derivatives A and B from Epimedium sagittatum and application thereof can effectively solve the problem of preparing tocopherol derivatives A and B from Epimedium sagittatum and realize the application in preparing anti-breast tumor drugs. The method is as follows: the aboveground part of Epimedium sagittatum is crushed, extracted by refluxing with ethanol, recovered under reduced pressure, extracted, separated by chromatography, eluted by gradient, recovered under reduced pressure, identified by thin layer spotting, combined, purified, collected in the retention time, dried, and obtained. The raw material is abundant, the preparation method is easy to operate, the obtained product is good in quality and good in use effect, can be effectively used for treating breast cancer, realizes the application in preparing anti-breast cancer drugs, develops the medicinal value and commercial value of Epimedium sagittatum, and has remarkable economic and social benefits.

This invention relates to the field of medical pharmaceutical technology, and in particular to the application of peony oil in the preparation of a drug for treating benign prostatic hyperplasia (BPH). The preparation method of the peony oil includes the following steps: selecting peony plants, peeling peony seeds from the plants as raw materials, crushing and grinding the dried peony seeds using a crushing device to obtain granular raw materials, placing the granular raw materials in a container and adding an organic solution, soaking them in a cool place, then heating and refluxing for extraction, collecting the volatile oil to obtain peony oil, and filtering the peony oil through multiple layers to form peony oil. The application of this peony oil in the preparation of a drug for treating BPH utilizes abundant raw materials for peony oil extraction, and the preparation method is simple and low-cost. Peony flowers are used as the sole active ingredient in the extraction of peony oil, which can be effectively used to treat BPH, expanding the medicinal value of peony flowers and alleviating the suffering of patients during their illness.
