The invention provides a method for removing coumarin in natural perfume. The method comprises the following steps: dissolving the natural perfume by using a solvent, adding an alkaline substance to adjust the pH value, carrying out a heating reflux reaction, concentrating after the reaction, extracting a concentrate by using an organic solvent, and carrying out reduced pressure distillation on extract liquor to remove the organic solvent, thereby obtaining the coumarin-removed natural perfume. By adopting the method for removing the coumarin in the natural perfume, the coumarin in the natural perfume such as hierochloe odorata extract, sweet clover extract, grain rain grass extract, cassia oil, pyrola calliantha extract and fenugreek tincture can be effectively removed, the coumarin content of the obtained coumarin-removed natural perfume product is less than 0.5 mu g / g, and the safety and application range of the product are greatly improved. The preparation method is simple in operation process, low in cost and very suitable for industrial production.

The UHPLC fingerprint spectrum establishment method and application of the traditional Chinese medicine composition of the present application, rhizoma drynariae 15 parts, 12 parts of dracaena, 10 parts of ligustrum lucidum aiton, 10 parts of caesalpinia, 10 parts of pyrola calliantha and 10 parts of radix cyathulae are made into traditional Chinese medicine composition water decoction, vacuum freeze drying is prepared by vacuum concentration, freeze-dried powder, the quality control of traditional Chinese medicine composition is carried out by establishing UHPLC fingerprint spectrum, and the content of multiple index components of the traditional Chinese medicine composition is determined under the same chromatographic condition, and the quantity value transmission relationship of multiple index components is further determined, the quality control from single object to "composition-herb" whole chain quality monitoring is realized, and the comprehensiveness and effectiveness of quality control are significantly improved.

The present invention discloses a traditional Chinese medicine composition with skin anti-inflammatory and repair effects and its application. The traditional Chinese medicine composition includes extracts of Hedyotis diffusa, Pyrola calliantha, Prunella vulgaris, and Sophora flavescens. Among them, the mass ratio of the extract of Hedyotis diffusa: the extract of Pyrola calliantha: the extract of Prunella vulgaris: the extract of Sophora flavescens = 1-100: 1-100: 1-50: 1-50, and its solid-liquid ratio is 0.001%-10%. The present invention prepares a traditional Chinese medicine composition with skin anti-inflammatory and repair effects through synergistic enhancement. Using the extracts of Hedyotis diffusa, Pyrola calliantha, Prunella vulgaris, and Sophora flavescens as raw materials and with ingredient compatibility, it solves the problem of the anti-inflammatory efficacy limitation of a single raw material; preparing a traditional Chinese medicine composition of Hedyotis diffusa, Pyrola calliantha, Prunella vulgaris, and Sophora flavescens helps with the anti-inflammatory efficacy.

The application discloses a natural plant-extracted self-suction type plant insecticide and a preparation and use method thereof, and belongs to the field of agricultural biotechnology. The insecticide is prepared by step-by-step decocting, filtering, purifying and pasteurizing pinellia ternate, cyperus rotundus, cinnamomum cassia, pyrola calliantha and cypress leaves. The insecticidal active substances of each component selected in the application are mainly small-molecule alkaloids, flavones and aldehyde substances, have strong penetration capacity and are easily absorbed by the digestive tract of pests; the pesticide solution can form a negative pressure in the catheter of the trunk or branch incision wound surface by means of plant transpiration, is self-sucked and transported to branches and leaves along the transpiration flow, belongs to a true green self-suction type insecticide, and when the pesticide is applied, drilling and medicine injection are not needed, external force is not needed to press, a tree bark superficial wound surface pasting method is adopted, the wood layer of the tree is not damaged, and damage to the growth of the tree is avoided.

The present application belongs to the field of traditional Chinese medicine identification, and particularly relates to a chromatographic method for identifying true and false Pyrola calliantha. The present application primarily establishes a characteristic chromatogram of Pyrola calliantha reference substance through liquid chromatography-mass spectrometry technology, and then attributes characteristic peaks in the characteristic chromatogram according to the chromatographic peaks of the index component reference substance, and then detects and identifies the test sample. The method comprehensively reflects the characteristics of Pyrola calliantha and its counterfeit products, provides a new analysis method for the internal quality control of Pyrola calliantha medicinal materials, and is suitable for not only Pyrola calliantha and its counterfeit medicinal materials, but also medicinal slices, standard decoctions and / or formula granules. The method is simple, accurate and reliable, easy to operate, short in time, low in solvent consumption and small in environmental pollution. The method has the advantages of strong specificity, high stability and good repeatability, and is particularly suitable for detection and monitoring of large-scale production.
