Embodiment 1

[0019] Clean the lotus pods, remove impurities, cut them into pieces, and try to reflux extract with 50% ethanol solution, the ratio of solid to liquid is 1:15, extract twice, each time for one hour, the extraction temperature is 65°C, and filter. Take the filtrate to recover ethanol, put the concentrated solution on a macroporous resin column, wash away impurities with 4BV of distilled water at 4BV / h, then elute with 6BV of 50% ethanol solution at 2BV / h, collect the eluate, and recover ethanol from the eluate Afterwards, concentrated and dried to obtain proanthocyanidin extract.

Embodiment 2

[0021] Clean the lotus pods, remove impurities, cut them into pieces, infiltrate with 50% ethanol solution until it is almost colorless, filter, take the filtrate to recover ethanol, put the concentrated solution on a macroporous resin column, use 3BV of distilled water at a rate of 3BV / h After washing away impurities, elute with 6BV of 50% ethanol solution at 2BV / h, collect the eluate, recover ethanol from the eluate, concentrate, dry, and obtain proanthocyanidin extract.

Embodiment 3

[0023] Clean the lotus pods, remove impurities, cut them into pieces, add water to make the ratio of material to liquid 1:25, decoct twice, 1 hour each time, combine the decoctions, filter, take the filtrate to concentrate, and put the concentrate on a macroporous resin column , After washing away impurities with 4BV of distilled water at 4BV / h, elute with 5BV of 50% ethanol solution at 2BV / h, collect the eluate, recover ethanol from the eluate, concentrate, dry, and obtain proanthocyanidin extract.

Abstract

The invention discloses a process for extracting procyanidine from receptaculum nelumbinis. The characteristic that the procyanidine content is enriched in the receptaculum nelumbinis is utilized, and the procyanidine extract is prepared by steps of shearing, refluxing (infiltration or decoction), filtering, column exchange, eluting, and performing concentration drying. The procyanidine content in the receptaculum nelumbinis is far higher than that in grape seeds, the receptaculum nelumbinis becomes another raw material for of procyanidine, and the method has wide market prospects and is an ideal choice for modern healthcare product production enterprises.

Description

technical field [0001] The invention relates to a method for extracting health care products, in particular to a method for extracting 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 proan...
