Abstract

The invention discloses an extraction method of alpinia zerumbet essential oil, which comprises the following steps: taking alpinia zerumbet fruits, pulverizing, and screening with a 20-60-mesh sieveto obtain powder; adding water into the powder, uniformly mixing, soaking for 10 to 30min, and then carrying out ultrasonic treatment for 5 to 10min under the condition of 40 to 60 DEG C; distilling and extracting the mixed solution for 200 to 300min by adopting a steam distillation method; adding sodium chloride powder into the mixed solution to enable the mass concentration of sodium chloride inthe solution to reach 1.0-1.6%, and continuously distilling and extracting for 30-60 minutes; collecting distilled distillate, performing standing, separating to obtain upper oily liquid, adding anhydrous sodium sulfate into the upper oily liquid, shaking, and separating to remove the anhydrous sodium sulfate, thereby obtaining the product. The method can effectively solve the problems of low extraction efficiency and long extraction time in the existing alpinia zerumbet essential oil extraction process.

Description

technical field [0001] The invention relates to the technical field of essential oil extraction, in particular to a method for extracting the essential oil of Alpinia japonicus. Background technique [0002] Zingiber officinale: Zingiber officinale plant, plant height up to 3 meters, leaves lanceolate, base tapering, margins pubescent, both sides glabrous; panicles are raceme, drooping, inflorescence rachis purple Red, very short branches, bracteoles oval, white, pink at the top, enveloping the flower in bud, oblong lobes, milky white, pink at the top, spoon-shaped broad ovate lips, ovary covered with golden yellow coarse hairs ; Seeds angular. Flowering from April to June; fruiting from July to October. Yanshan ginger is an important spice plant in my country. It has been widely planted in southern Sichuan in recent years. Studies have shown that it is rich in volatile oil and has various biological activities such as antibacterial, anti-oxidation, analgesic and anti-infl...
