Embodiment 1

[0017] 1. Clean the lotus pods, remove impurities and cut them into pieces;

[0018] 2. Add 20% ethanol solution for ultrasonic extraction, the ultrasonic frequency is 30kHz, the ultrasonic power is 400W, the material-liquid ratio of lotus pod and ethanol is 1g:8ml, extract once, 8min each time, and the extraction temperature is 25°C;

[0019] 3. Filtrate, concentrate the filtrate, put the concentrated solution on a macroporous resin column, wash away impurities with 2BV of distilled water at 3BV / h, then elute with 50% ethanol solution at 2BV / h, collect the eluent, and elute After recovering ethanol from the liquid, concentrate and dry to obtain proanthocyanidin extract.

[0020] The processing method of described macroporous resin is:

[0021] Soak the new resin in absolute ethanol for 24 hours, fully swell and wash with ethanol until the effluent is not cloudy when added with water, then wash with distilled water until there is no alcohol smell for later use; the model of t...

Embodiment 2

[0023] 1. Clean the lotus pods, remove impurities and cut them into pieces;

[0024] 2. Add 80% ethanol solution for ultrasonic extraction, the ultrasonic frequency is 60kHz, the ultrasonic power is 800W, the material-liquid ratio of lotus pod and ethanol is 1g: 20ml, extract 3 times, 50min each time, and the extraction temperature is 60°C;

[0025] 3. Filtrate, concentrate the filtrate, put the concentrated solution on a macroporous resin column, use 3BV of distilled water to wash away impurities at 5BV / h, then use 70% ethanol solution to elute at 4BV / h, collect the eluate, and elute After recovering ethanol from the liquid, concentrate and dry to obtain proanthocyanidin extract.

[0026] The processing method of described macroporous resin is:

[0027] Put the new resin into the adsorption column, soak it with 95% ethanol for 24 hours, pass through the resin layer with distilled water at a flow rate of 2BV / h, wash until the effluent is not white and turbid after adding wate...

Abstract

The invention discloses a method for ultrasonic extraction of procyanidine in receptaculum nelumbinis. The method comprises the following steps: cleaning the receptaculum nelumbinis, removing impurities and cutting into pieces; carrying out ultrasonic extraction by an ethanol solution; filtering, concentrating and drying to obtain a procyanidine extract. The procyanidine in the receptaculum nelumbinis is prepared from dry receptaculum nelumbinis as a raw material; the obtained procyanidine in the receptaculum nelumbinis is large in amount, good in curative effect, and more convenient to produce, the process is greatly simplified, and the method has great practical significance and promotional value.

Description

technical field [0001] The invention relates to an extraction method of ultrasonic technology, in particular to an extraction method of lotus pod proanthocyanidins. Background technique [0002] The lotus pod is the mature receptacle of Nelumbo Nucifera Gaertn, a medicinal plant of Nelumbo Nucifera Gaertn, also known as lotus shell, lotus shell, and lotus pod. According to the "Compendium of Materia Medica", the lotus pod has the effect of reducing fatigue and stopping bleeding, and is used for metrorrhagia, hematuria, and bleeding from hemorrhoids. The 2010 edition of "Chinese Pharmacopoeia" contains dried lotus pods, which are harvested when the fruits are ripe in autumn, removed and dried in the sun. The lotus pod contains hyperoside, quercetin-3-diglucoside and a small amount of nilumbine, etc. In addition, the lotus pod also contains chemical components such as carbohydrates, vitamins, and quercetin. In recent years, studies have shown that lotus pods are rich in proa...
