Embodiment Construction

[0038] The present invention will be specifically introduced below in conjunction with specific embodiments.

[0039] A method for optimizing the extraction method of lily flavonoids, comprising the steps of:

[0040] Step 1, crushing the lily bulbs and sieving; as a preferred method, passing through a 60-mesh sieve.

[0041] Step 2, weighing lily powder, adding concentration is 50-90% ethanol solution, the mass ratio of the volume of ethanol solution and lily powder is 4:1-20:1ml / g; As a kind of preference, weigh lily powder, A 71% ethanol solution is added, and the mass ratio of the volume of the ethanol solution to the lily powder is 12:1ml / g.

[0042] Step 3, put the ethanol solution mixed with lily powder into an ultrasonic cleaner to extract, filter with suction after extraction, and ultrasonic at least once for 20-100 minutes;

[0043] As a preference, put the ethanol solution mixed with lily powder into an ultrasonic breaker with a water bath temperature of 50° C. an...

Abstract

The invention discloses an extraction method of lily bulb flavone and an optimization method of the extraction method. The extraction method comprises the following steps of step I, crushing lily bulbs, and performing screening; step II, weighing lily bulb powder, and adding an ethanol solution of which the concentration is 50-90%, wherein the ratio of volume of the ethanol solution to the mass ofthe lily bulb powder is (4:1) to (20:1)ml / g; step III, placing the ethanol solution in which the lily bulb powder is mixed in an ultrasonic breaker of which the water bath temperature is 20-90 DEG Cand the frequency is 100Hz, performing extraction, and after extraction, performing sucking filtration, wherein number of ultrasonic times is 1-3, and the ultrasonic time is 20-100min; and step VI, after ultrasonic extraction, performing sucking filtration, merging filtrate, and concentrating the merged filtrates with a rotation evaporimeter so as to obtain the lily bulb flavone. According to theoptimization method, ultrasonic waves are used for assisting in the extraction method, and through combination of a response surface, and systems software Design Expert, the best extraction conditionfor the total flavone in the lily bulbs is optimized. The extraction rate is increased, and the technology is stable and reliable and high in maneuverability.

Description

technical field [0001] The invention relates to the field of plant compound extraction, in particular to an extraction method of lily flavonoids and an optimization method thereof. Background technique [0002] Lily, the dried fleshy scale leaves of Lilium lily or Lilium microphyllum, has the effects of nourishing the lungs, calming the nerves, and beautifying the skin. "Shen Nong's Materia Medica" records: "Lily has a sweet taste and a flat nature. It is mainly used to treat abdominal distension, heartache, urine and defecation, and nourish the middle and Qi." Lily is a commonly used traditional Chinese medicine for both medicine and food. Lily has the effects of nourishing yin and moistening the lungs, clearing the heart and calming the nerves. Lily can also be used for food therapy, which has the effects of relieving cough and asthma, lowering blood sugar, anti-tumor, improving sleep, improving immunity, and preventing senile dementia. At present, scholars at home and a...
