Abstract
The invention relates to an extraction method of lemongrass essential oil, belonging to the technical field of plant essential oil extraction. According to the invention, a solvent extraction method and a low-temperature distillation method are mainly used for extraction. The method comprises the following steps: repeatedly pouring an petroleum ether solvent on the pre-extracted lemongrass; putting the lemongrass into a distiller, heating at the lower part to generate steam so as to ensure that the essential oil of the lemongrass is volatilized along with the steam; collecting and cooling the steam containing the essential oil after passing through a pipe connected with the distiller; cooling the steam into liquor, and separating according to the ratio of water to essential oil and the difference of densities. The lemongrass extractive contains multiple types of nutrient substances, and can be widely used for additives of products such as foods, cosmetics and medicines.
Description
Technical field
The present invention relates to a kind of extracting method of essential oil, particularly a kind of extracting method of lemongrass essential oil belongs to plants essential oil extractive technique field.
Background technology
Lemongrass claims again West Indian lemon grass, has stomach invigorating, diuresis, prevents anaemia and skin care, and spleen-and-stomach-invigorating is dispelled flatulence, pain, helps digest.The tool antibacterial ability can be treated cholera, acute gastroenteritis and chronic diarrhoea, and Glycerin helps the usefulness of women's skin maintenance.Alleviate cold symptoms, can treat for stomachache, suffer from abdominal pain, have a headache, have a fever, remove headache, heating, bleb etc., oedema and superabundant fat are eliminated in the diuresis detoxifcation.Containing a large amount of vitamins Cs, also is the good merchantable brand of cosmetology.Regulate fat secretion, be of value to oiliness skin quality and hair quality, can be added to the water cleaning skin, stimulate circulation.The objective of the invention is for a kind of method of efficiently, fast extracting the lemongrass essential oil is provided, fully keep its abundant nutritive value and pharmacological effect, the additive that can be widely used in the products such as food, makeup, medicine uses.
Summary of the invention
The objective of the invention is in order to disclose a kind of extracting method of lemongrass essential oil, extraction yield is high, and quality is good, and is simple for process.
Technical scheme of the present invention: a kind of extracting method of lemongrass essential oil:
(1) first lemongrass is cleaned totally, be cut into broken end, stand-by; (2) repeatedly drench on the broken end of lemongrass of pre-extraction with petroleum ether solvent; (3) then put it in the distiller, add thermogenesis steam by the below, allow the essential oil of lemongrass follow the steam volatilization; (4) collect: collect the water vapour that contains essential oil with the conduit that connects on the distiller; (5) cooling, after steam cooling became liquid, according to the proportion of water and essential oil, the differential liberation of density out namely got the lemongrass essential oil.
Beneficial effect of the present invention: the present invention takes solvent extration and low-temperature distillation method to extract, and has improved the oil yield of lemongrass essential oil, save energy, and technique is simple, and leaching process is pollution-free, and cost is lower.
