Abstract
The invention discloses a method for extracting lavender flavone. The method comprises the following steps: by adopting an ultrasonic-assisted mode, by taking ethanol as a solvent, extracting flavone, performing suction filtration, and performing rotary evaporation to obtain a lavender flavone extract. The key points are that the conditions of ultrasonic-assisted extraction and rotary evaporation are selected and controlled, wherein during ultrasonic-assisted extraction, the ultrasonic frequency is 40-50KHz, the temperature is 67-80 DEG C, and the extraction time is 25-40 minutes; and during rotary evaporation, the rotating speed is 95-120 revolutions per minute, the temperature is 70-80 DEG C, and the time is 13-32 minutes. The method is simple and feasible and convenient to produce and apply, and the extraction cost can be reduced.
Description
Technical field
The present invention is a kind of extracting method of lavandula angustifolia flavone, belongs to field of plant extraction.
Background technology
Lavandula angustifolia (Lavender) is the dry aerial parts of labiate lavandula angustifolia, Xinjiang Yili of China has become the main producing region of national lavandula angustifolia at present, Uygur medicine thinks that lavandula angustifolia character is that secondary is damp and hot, can dissipate cold, mend stomach reason brain, dampness pain relieving, be used for the treatment of the diseases such as chest and abdomen swelling and pain, flu cough with asthma, dizziness headache, shortness of breath and palpitation, joint osteodynia.
Lavandula angustifolia is rich in volatile ingredient, in recent years mainly concentrates on the research to its volatile chemical component both at home and abroad.The separation from lavandula angustifolia such as Wu Xia obtains 7 flavone compounds such as apigenin, and Yang Jie etc. study flavone antioxidant activity in the narrow leaf lavandula angustifolia in Xinjiang, and research shows that lavandula angustifolia flavone has stronger antioxidant activity, has value of exploiting and utilizing.
The present invention adopts ultrasound wave assisted Extraction to follow the example of, and ethanol carries out the extraction of flavone as solvent, take flavone extraction ratio as index, determines that lavandula angustifolia flavone extracts optimum condition.
Summary of the invention
Technical scheme the invention provides a kind of extracting method of lavandula angustifolia flavone, and particular content is as follows:
A, pre-treatment:
By lavandula angustifolia rinsing, drying, be ground into and cross 30 mesh sieves after powder;
B, flavone extract: using 50%-70% ethanol as solvent, by solid-liquid ratio 1:25-1:40, adopt ultrasound wave assisted extraction, supersonic frequency 40-50KHz, 67 ℃-80 ℃ of temperature, extract 25-40min, sucking filtration, collect filtrate, be rotated evaporation, rotating speed 95-120r/min, temperature 70-80 ℃, time 13-32min, obtains lavandula angustifolia flavone extract.
the specific embodiment
embodiment 1
By lavandula angustifolia rinsing, drying, be ground into after powder and cross 30 mesh sieves, by solid-liquid ratio 1:30, lavandula angustifolia powder is joined in 55% ethanol, adopt ultrasound wave assisted extraction, frequency 40KHz, temperature 60 C, extraction time is 30min, while hot after sucking filtration, be rotated evaporation, rotating speed 100r/min, temperature 70 C, extract 30min, obtain lavandula angustifolia flavone extract.
embodiment 2
By lavandula angustifolia rinsing, drying, be ground into after powder and cross 30 mesh sieves, by solid-liquid ratio 1:35, lavandula angustifolia powder is joined in 65% ethanol, adopt ultrasound wave assisted extraction, frequency 45KHz, temperature 70 C, extraction time is 35min, while hot after sucking filtration, be rotated evaporation, rotating speed 110r/min, 75 ℃ of temperature, extract 25min, obtain lavandula angustifolia flavone extract.
