The invention is characterized in that raw materials are powdery wild lavenders. In the present invention, extracted compositions of wild lavenders are compatible with daily chemical products to calm unstable emotions and alleviate tension and anxiety. The extracted compositions of the present invention possess effective curative effects and are suitable for those who suffer from neurasthenia and insomnia.
Description
Technical field:
The present invention relates to the preparation method that a kind of lavandula angustifolia has the composition of effects of tranquilizing and allaying excitement, more particularly take supercritical CO
2Extraction extracts composition and the application process thereof that has effects of tranquilizing and allaying excitement in the lavandula angustifolia.
Background technology:
Neurasthenia, insomnia are one of modern diseases, and people strengthen day by day to the care that relaxes neurasthenia and insomnia.Usually take benzene for the insomniac and wait antidepressants and sleeping pill etc., but these hypnotic drugs are taken meeting generation dependency and side effect for a long time than appropriate.Lavandula angustifolia contains complicated chemical analysis, contains compositions such as linalyl acetate, linalool, acetic acid lavandula angustifolia ester, and the method extraction ratio of producing the active ingredient of lavandula angustifolia fragrance at present is very low.The present invention is exactly in order to provide without any side effects to human body, has the method and the application process thereof of extraction of the lavandula angustifolia active ingredient of effects of tranquilizing and allaying excitement.Find through supercritical CO after deliberation
2The lavandula angustifolia active ingredient that extraction extracts has good effects of tranquilizing and allaying excitement.
Summary of the invention:
The object of the present invention is to provide a kind of supercritical CO of using
2Extraction extracts composition and the application process thereof that has effects of tranquilizing and allaying excitement in the lavandula angustifolia.Its main component is linalyl acetate, linalool, acetic acid lavandula angustifolia ester, and it has the effect that the unease mental status is had calm effect and alleviates intense strain.Advantage of the present invention is the tranquillizing and allaying excitement effect that adopts the gas of the suitable fragrance of people's sense organ to have, and is applied to the articles for daily use, obtains the good sedative effect of calming the nerves in comfortable fragrance scope.
Technical scheme of the present invention is achieved in that uses supercritical CO
