The present invention is ultrasonic usnic acid extracting process. Cut usnea is added with 75-98 % concentration alcohol solution in 2-6 times, and ultrasonically extracted at the frequency of 30-50 KHz for 10-50 min, and through further filtering to obtain filtrate, concentrating while recovering alcohol and vacuum freeze drying, usnic acid is obtained. The present invention has high usnic acid extracting rate, can save usnea resource, and has simple technological process, low power consumption and low cost.

The invention discloses an extraction method of active ingredients of a traditional Chinese medicinal material rhubarb, belonging to the technical field of traditional Chinese medicine extraction and aiming to provide a new rhubarb extraction method with high efficiency and good extraction effects. The extraction method is characterized in that extraction is carried out by adopting twice water extraction modes, wherein the extraction conditions are as follows: 7-8 times amount of water is added during first extraction, 5-6 times amount of water is added during second extraction, the temperature is maintained at 96+ / -2 DEG C after boiling, and the extraction time every time is one hour. The method is mainly used for extracting the active ingredients of the traditional Chinese medicinal material rhubarb.

The invention discloses a preparation method of a haemorrhoids tablet, belongs to the technical field of preparation of traditional Chinese medicines and aims at providing a novel method with high extraction efficiency and good medicinal effect of a product for preparing the haemorrhoids tablet. The preparation method is characterized by comprising the following steps of crushing part of radix angelicae dahuricae into fine powder; decocting residual radix angelicae dahuricae, fructus tribuli and leatherleaf mahonia stem and extracting; decocting and extracting radix et rhizoma rhei; concentrating an extracting solution; mixing thick paste with the radix angelicae dahuricae powder and biliary powder from pig; granulating, drying and mixing a mixture with borneol; adding an accessory and then performing tabletting, wherein extracting conditions of the radix et rhizoma rhei are that 7 to 8 times of water is added for the first time, 5 to 6 times of water is added for the second time, after boiling, the temperature is kept at at 96+ / -2DEG C, and extracting is performed for one hour each time.

The present invention relates to a raw material containing phenylethanol glycoside produced from Cistanche deserticola by applying membrane separation technology and a preparation method thereof. The raw material containing phenylethanol glycoside obtained from Cistanche deserticola in the present invention contains verbascoside > 40%, and the preparation method mainly includes Material selection, extraction, microfiltration, ultrafiltration, nanofiltration, drying and other processes. Compared with the prior art, the transfer rate of the active ingredients extracted from Herba Cistanche by the method of the present invention has been greatly improved, while the dry paste yield has been reduced to a certain extent, and the active ingredients in Herba Cistanche have been effectively enriched , under the premise of not changing the structure of the active ingredient, the extraction rate of the active ingredient is improved, the production cost is saved, and the process cycle is shortened.

The invention relates to the field of traditional Chinese medicines, especially relates to the field of traditional Chinese medicines and health products and concretely relates to ergosterol-rich ganoderma lucidum spore oil and a preparation method thereof. Aiming at ganoderma lucidum spore oil extraction, the novel ergosterol-rich ganoderma lucidum spore oil extraction method is provided and through the extraction method, the ergosterol-rich ganoderma lucidum spore oil with high ergosterol content is obtained. The ergosterol-rich ganoderma lucidum spore oil has ganoderma triterpene content of 40-50wt% and ergosterol content of 0.83wt% or more. The preparation method utilizes water as a dissolving medium, is free of an organic solvent, is suitable for medicine and food industries, is free of a subsequent treatment process and saves a treatment cost. The preparation method is free of carbon dioxide supercritical extraction equipment, has a low cost and high safety and has ganoderma triterpene and ergosterol extraction rates higher than those of the traditional method.

The invention discloses a method for extracting a privacy policy embedded in an APK file of a mobile application, which belongs to the field of analysis and detection of Android mobile terminal application software. Crawl the content of each webpage and extract the feature words in the privacy policy text. At the same time, collect the characteristic words of several web pages to train the binary classification model in advance; input each characteristic word of the APK file to be detected into the trained binary classification model one by one, and judge whether there is a privacy policy page in the output result, and if so, output the privacy policy And end; otherwise, conduct automated dynamic testing, extract the corresponding URL links by monitoring the request address in the traffic, crawl the content of each page to extract feature words, and enter the binary classification model to judge until the privacy policy page is found or exceeds the set value End of traversal depth. The invention improves the extraction efficiency and success rate of the privacy policy through the combination of dynamic and static tests.

The invention discloses an artemisia rupestris preparation used in medicaments for treating diabetes and a preparation method thereof. The preparation method comprises the following steps: crushing artemisia rupestris herbs; weighing the powder; adding ethyl ether of which the volume is 3 times of the volume of the powder; standing for 8 hours, and then, filtering; ultrasonically extracting precipitates with 80% ethanol at 35 DEG C for 30-40 minutes every time; filtering to obtain an ethanol extracting solution; precipitating with 95% ethanol, centrifuging, and taking a supernatant solution; extracting ethyl acetate; filtering to obtain an ethyl acetate part; carrying out polyamide column chromatography on the ethyl acetate part; eluting by sequentially adopting ethanol solutions with different concentrations of 20%, 40%, 60% and 80%; collecting ethanol eluate obtained by adopting the ethanol solutions with the concentrations of 60% and 80%; concentrating while depressurizing to obtain an extract; proportioning the obtained extract and a milk vetch extract according to the weight ratio of (5-10):1; and preparing a certain amount of pure water to obtain a finished preparation. The prepared artemisia rupestris preparation has the activity of reducing blood sugar, the using dose of the artemisia rupestris preparation is 67.5mg / kg, and the artemisia rupestris preparation has wide application fields in medicaments for treating diabetes.
