Abstract

The invention discloses a kind of Sal to urge to ooze the method extracting tea saponin from cake of camellia oleifera seeds, comprise the following steps: cake of camellia oleifera seeds is put in 2-3 times amount acetone and pull an oar, stir 1-2 hour, filter, obtain filtering residue；Being added by filtering residue in the 40-50% alcoholic solution of 5-8 times amount, heating is to 50-60 DEG C, and adding acetic acid adjustment pH value is 5-6, stirs 2-3 hour, is simultaneously introduced the aluminium hydroxide being equivalent to the bamboo charcoal powder of Oil-tea-cake weight 2-3%, the Sal of 2-3%, 2-3%；Filter to get filtrate and cake slag；Tea saponin yield of the present invention more than 90%, gained tea saponin product purity >=90%。

Description

A kind of Sal is urged to ooze the method extracting tea saponin from cake of camellia oleifera seeds

Technical field

The present invention relates to a kind of method extracting tea saponin from cake of camellia oleifera seeds。

Background technology

Tea saponin is a kind of pure natural nonionic surfactant, is widely used in daily-use chemical industry and makes detergent (such as shampoo, silk and woollen detergent etc.), feed additive, the emulsifying agent of pesticide, synergist, antibacterial and insecticide。

At present, tea saponin extracting method from cake of camellia oleifera seeds is a lot, all there is productivity not high, and yield is not high, the problems such as impurity is many, degeneration。

Summary of the invention

It is an object of the invention to provide a kind of Sal to urge to ooze the method extracting tea saponin from cake of camellia oleifera seeds, yield is high, and impurity is few。

Technical scheme is as follows:

A kind of Sal is urged to ooze the method extracting tea saponin from cake of camellia oleifera seeds, it is characterised in that comprise the following steps:

(1), by cake of camellia oleifera seeds put in 2-3 times amount acetone and pull an oar, stir 1-2 hour, filter, obtain filtering residue；

(2), by filtering residue adding in the 40-50% alcoholic solution of 5-8 times amount, heating is to 50-60 DEG C, and adding acetic acid adjustment pH value is 5-6, stirs 2-3 hour, is simultaneously introduced the aluminium hydroxide being equivalent to the bamboo charcoal powder of Oil-tea-cake weight 2-3%, the Sal of 2-3%, 2-3%；Filter to get filtrate and cake slag；

(3), by cake slag adding 5-6 times amount water dissolution, heating, to 70-80 DEG C, is stirred 2-3 hour, adds sodium hydroxide, and adjustment pH value is 9-10；It is filtrated to get filtrate；

(4), step (2), (3) filtrate being merged, add the active carbon powder being equivalent to the kieselguhr of Oil-tea-cake weight 1-2%, 0.2-0.3%, heating, to 40-50 DEG C, is stirred, is filtered to get filtrate；

(5), gained filtrate aperture is the ceramic membrane filter of 0.1-0.2 μm；

(6), by filtrate through spray drying, tea saponin is obtained。

Present invention have the advantage that

1, tea saponin acquirement rate is high, extracts its tea saponin residual quantity of the de-soap dregs of rice after tea saponin less than 2%；

2, tea saponin yield of the present invention is more than 90%, gained tea saponin product purity >=90%。

Detailed description of the invention

A kind of Sal is urged to ooze the method extracting tea saponin from cake of camellia oleifera seeds, comprises the following steps:

(1), by cake of camellia oleifera seeds put in 3 times amount acetone and pull an oar, stir 2 hours, filter, obtain filtering residue；

(2), by filtering residue add in 50% alcoholic solution of 8 times amount, heating to 50-60 DEG C, add acetic acid regulate pH value be 5, stir 3 hours, be simultaneously introduced be equivalent to the bamboo charcoal powder of Oil-tea-cake weight 2%, 3% Sal, 3% aluminium hydroxide；Filter to get filtrate and cake slag；

(3), by cake slag adding 6 times amount water dissolutioies, heating, to 70-80 DEG C, is stirred 2 hours, adds sodium hydroxide, and adjustment pH value is 9-10；It is filtrated to get filtrate；

(4), by step (2), (3) filtrate merge, add be equivalent to the kieselguhr of Oil-tea-cake weight 2%, 0.2% active carbon powder, heating to 40-50 DEG C, stirring, filter to get filtrate；

(5), gained filtrate aperture is the ceramic membrane filter of 0.1-0.2 μm；

(6), by filtrate through spray drying, tea saponin is obtained。

After testing, this tea saponin yield is 19%, and product purity is 93%。
