Abstract
The invention discloses a method for extracting piperis longi volatile oil and particularly relates to a method for extracting piperis longi volatile oil by employing double-frequency ultrasonic wave. The method comprises the following processing steps: (1) pretreatment of piperis longi medicinal material; (2) double-frequency ultrasonic wave extraction; and (3) extraction by using an organic solvent, drying and dewatering anhydrous sodium sulfate, and carrying out vacuum concentration so as to obtain the piperis longi volatile oil. The piperis longi volatile oil is extracted by adopting the double-frequency ultrasonic wave, the method is simple in process, short in extraction time and low in energy consumption, the yield of volatile oil is significantly higher than that of the traditional extraction method, and the method is suitable for industrial production.
Description
Technical field
The present invention relates to a kind of extracting method of Bi roots of grass volatile oil, be specifically related to a kind of method that adopts dual-frequency ultrasonic wave to extract Bi roots of grass volatile oil, belong to active ingredient of natural product extractive technique field.
Background technology
The Bi roots of grass, has another name called that Bi Bo, Bi dial pears, Ah pears scold top etc., is dry near maturation or the mature fruit cluster of the piperaceae plant Bi roots of grass, herbaceous perennial vine.Its fruit ear is used as medicine, pungent, hot.Return stomach, large intestine channel.Have warming spleen and stomach for dispelling cold, effect of lower gas pain relieving, is used for treating coldness and pain in the epigastrium, and vomiting, has loose bowels, migraine; Control toothache outward.Volatile oil is one of main active ingredient of the Bi roots of grass, and wherein chief component is β-selinene, β-cubebene, α-zingiberene, pentadecane, α-Humuleno, 1-17 alkene, 17 alkene and heptadecane etc.
The extracting method of existing volatile oil has a variety of, as solvent extration, cold press process, supercritical fluid extraction, open steam distillation method etc.Solvent extration cost is higher, easily introduces impurity, and its operation is numerous and diverse and easily cause the loss of volatile oil, does not generally adopt; Cold press process is carried out at normal temperatures, and the volatile oil of gained contains the impurity such as moisture, phlegmatic temperament and cell tissue, need to be refining through centrifugal, distillation, dehydration etc., and be difficult to volatile oil all to squeeze out; Supercritical fluid extraction is a kind of new extracting method, extract volatile oil ability strong, have anti-oxidation, pyrolysis and improve the advantages such as volatile oil quality, but this technique needs high-tension apparatus, technical requirements is high, cost of equipment investment is large, apply also not generally, therefore, the extraction of volatile oil now mostly adopts easy open steam distillation method, but volatile oil extraction yield is not high, and high boiling composition is difficult to detect.
The present invention adopts dual-frequency ultrasonic wave method to extract Bi roots of grass volatile oil, and with low cost, simple to operate, the extraction yield of volatile oil is higher.By literature search, have no the report that extracts Bi roots of grass volatile oil about this method.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, provide that a kind of technique is simple, extraction yield is high, solvent load is few and be easy to the method for the extraction Bi roots of grass volatile oil reclaiming.
The present invention includes following steps:
Bi roots of grass medicinal material drying is pulverized, crossed 60 mesh sieves, add 60 ~ 70% the ethanolic soln of 6 ~ 8 times, adopt dual-frequency ultrasonic wave to extract, ultrasonic power is 400 ~ 500W, extracts continuously 60 ~ 90min, filtration in 50 ~ 70 DEG C, filtrate is concentrated into without alcohol taste in Rotary Evaporators, organic solvent extraction 2 ~ 3 times, combining extraction liquid, anhydrous sodium sulfate drying dehydration, concentrating under reduced pressure, obtains Bi roots of grass volatile oil.
Described double-frequency ultrasound wave frequency is 20KHz and 40KHz.
Described ultrasonic power is that double-frequency ultrasound is made used time total power, and 20KHz and 40KHz respectively get half.
Described extraction solvent is the one in sherwood oil or ether.
Beneficial effect of the present invention is: double-frequency ultrasound extracts and reduced the dead angle that standing wave causes, make full use of the effects such as ultrasonic cavitation effect, heat effect and mechanical vibration, accelerated effective constituent and entered solvent, improve extraction yield, shorten extraction time, simplified operation steps.
Further illustrate the present invention below in conjunction with embodiment, but the scope of protection of present invention is not limited to following embodiment.

Embodiment 2:
Bi roots of grass medicinal material drying is pulverized, crossed 60 mesh sieves, add 65% the ethanolic soln of 7 times, adopt dual-frequency ultrasonic wave to extract, ultrasonic frequency is 20KHz, 40KHz, and power is that 500W(20KHz and 40KHz respectively get half), in 60 DEG C of continuous 70min that extract, to filter, filtrate is concentrated into without alcohol taste in Rotary Evaporators, extracted with diethyl ether 3 times, combining extraction liquid, anhydrous sodium sulfate drying dehydration, concentrating under reduced pressure, obtain thick safran Bi roots of grass volatile oil, yield is 5.01%.
Embodiment 3:
Bi roots of grass medicinal material drying is pulverized, crossed 60 mesh sieves, add 70% the ethanolic soln of 8 times, adopt dual-frequency ultrasonic wave to extract, ultrasonic frequency is 20KHz, 40KHz, and power is that 450W(20KHz and 40KHz respectively get half), in 70 DEG C of continuous 90min that extract, to filter, filtrate is concentrated into without alcohol taste in Rotary Evaporators, petroleum ether extraction 2 times, combining extraction liquid, anhydrous sodium sulfate drying dehydration, concentrating under reduced pressure, the green Bi roots of grass volatile oil that obtains transparent oily, yield is 2.21%.
