Abstract

The invention discloses a kind of method that macroporous adsorbent resin extracts tea saponin, (1), be added to the water by cake of camellia oleifera seeds, heating, to 70-80 DEG C, is simultaneously introduced the Sal being equivalent to the activated carbon powder of cake of camellia oleifera seeds weight 2-3%, 2-3%; Grind making beating 2-3 hour, add the aluminium hydroxide of 2-3%, stir 30-40 minute, stand 2-3 hour, filter to get filtrate and cake slag; (2), the filtrate of gained be cooled to-8 DEG C ~-5 DEG C, adding ammonia, to regulate PH be 9-10, adds the active carbon powder being equivalent to the kieselguhr of Oil-tea-cake weight 1-2%, 0.2-0.3%, filters to get filtrate, finally crosses macroporous adsorbent resin. Tea saponin yield of the present invention more than 90%, gained tea saponin product purity >=90%.

Description

A kind of macroporous adsorbent resin extracts the method for tea saponin

Technical field

The present invention relates to a kind of method that macroporous adsorbent resin extracts tea saponin.

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 method that macroporous adsorbent resin extracts tea saponin, yield is high, and impurity is few.

Technical scheme is as follows:

A kind of macroporous adsorbent resin extracts the method for tea saponin, it is characterised in that comprise the following steps:

(1), by cake of camellia oleifera seeds joining in 6-8 times amount water, heating, to 70-80 DEG C, is simultaneously introduced the Sal being equivalent to the activated carbon powder of cake of camellia oleifera seeds weight 2-3%, 2-3%; Grind making beating 2-3 hour, add the aluminium hydroxide of 2-3%, stir 30-40 minute, stand 2-3 hour, filter to get filtrate and cake slag;

(2), the filtrate of gained be cooled to-8--5 DEG C, adding ammonia, to regulate PH be 9-10, adds the active carbon powder being equivalent to the kieselguhr of Oil-tea-cake weight 1-2%, 0.2-0.3%, filters to get filtrate;

(3), filtrate be adjusted to neutrality, be configured to D-101 macroporous adsorptive resins on the aqueous solution that mass percentage concentration is 3-5%;

(4), successively with the sodium bicarbonate solution eluting macroporous adsorptive resins of the saline solution of 1-2%, 2-3%, then it is washed till neutrality with deionized water, then with the tea saponin on mass percentage concentration 50-80% ethanol desorbing macroporous adsorptive resins, obtains tea saponin solution;

(5), tea saponin solution is concentrated into dry, obtains powdery tea saponin.

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 macroporous adsorbent resin extracts the method for tea saponin, comprises the following steps:

(1), by cake of camellia oleifera seeds joining in 7 times amount water, heating, to 70-80 DEG C, is simultaneously introduced the Sal being equivalent to the activated carbon powder of cake of camellia oleifera seeds weight 2-3%, 2-3%;Grind making beating 2-3 hour, add the aluminium hydroxide of 2-3%, stir 30-40 minute, stand 2-3 hour, filter to get filtrate and cake slag;

(2), the filtrate of gained be cooled to-8--5 DEG C, adding ammonia, to regulate PH be 9-10, adds the active carbon powder being equivalent to the kieselguhr of Oil-tea-cake weight 1-2%, 0.2-0.3%, filters to get filtrate;

(3), filtrate be adjusted to neutrality, be configured to D-101 macroporous adsorptive resins on the aqueous solution that mass percentage concentration is 3-5%;

(4), successively with the sodium bicarbonate solution eluting macroporous adsorptive resins of the saline solution of 1-2%, 2-3%, then it is washed till neutrality with deionized water, then with the tea saponin on mass percentage concentration 50-80% ethanol desorbing macroporous adsorptive resins, obtains tea saponin solution;

(5), tea saponin solution is concentrated into dry, obtains powdery tea saponin.

After testing, tea saponin yield of the present invention is 16%, and product purity is 93%.
