Embodiment

[0035] (1) Take 70g of Shichangpu medicinal material, put it in a 1000ml round bottom flask, add 560ml of water, soak for 4h, extract respectively: 4h, 5h, 6h, 7h, 8h..., compare the volume of extracted Shichangpu volatile oil, as figure 1 As shown, when the extraction time is 6h, the volume of the initial extraction of the volatile oil of Shichangpu is constant, and the constant time of the initial extraction volume of the volatile oil of Shichangpu is determined to be 6h.

[0036] (2) Under the same conditions, take 70g of Acorus calamus again, put it in a 1000ml round bottom flask, add 560ml of water, soak for 4 hours, and initially extract for 6 hours. Carry out re-extraction, respectively at intervals of 2h, 4h, 8h, 12h, extract for 5h, and compare the volume of the volatile oil of Acorus calamus, as figure 2 As shown, when the interval time is 4h, the re-extraction volume of Shichangpu is the largest, so the interval time between re-extraction is determined to be 4h.

Abstract

The invention discloses a method for improving the extraction rate of volatile oil of rhizoma acori graminei by re-extraction. The method comprises inspecting the time until the constant initial extraction volume of volatile oil of rhizoma acori graminei by a steam distillation method, determining conditions of the re-extraction through determining the re-extraction interval time and the volume constant time, and verifying the extraction rates and extract ingredients of the initial extraction and re-extraction to determine the optimal re-extraction process conditions. Through the steam distillation re-extraction method, the extraction rate of volatile oil of rhizoma acori graminei is improved, the use rate of the rhizoma acori graminei is increased, recycling of traditional Chinese medicines, high efficiency and energy saving are promoted, and the use range of the volatile oil of traditional Chinese medicines in traditional Chinese medicine preparations, foods and cosmetics is widened.The extract volatile oil of rhizoma acori graminei has small damage to the components, has a high purification rate and has a good practical value.

Description

technical field [0001] The invention belongs to the technical field of volatile oil extraction methods, and in particular relates to a method for improving the extraction rate of volatile oil of Acorus calamus through re-extraction. Background technique [0002] The traditional Chinese medicine Shichangpu is the rhizome of the Araceae plant Shichangpu, which has the effect of rejuvenating and refreshing. It contains volatile components α-asarone (α-asarone), β-asarone (β-asarone), methyl eugenol (methy equens) and other substances. Modern pharmacological research shows that the volatile oil of Shichangpu has a strong sedative and hypnotic effect, and it is widely used in the treatment of coma, epilepsy, amnesia and dementia. Volatile oils, also known as essential oils, are a general term for a class of volatile oily liquids that are immiscible with water. They can volatilize at room temperature, and most of them have an aromatic smell. The components contained in volatile ...
