Embodiment 1

[0037] The present embodiment reduces the content of camphor in borneol water by the following methods:

[0038] Take 40mL of weakly acidic cationic resin D113, equilibrate the column with an appropriate amount of purified water, and wash the resin. Then 320 mL of borneol water was loaded into the sample. The flow rate is 2 times the column volume per hour, collect the sample effluent, and perform GC detection; after collecting the sample effluent, take 80mL of 5% sodium chloride solution, and the flow rate is 2 times the column volume per hour for column cleaning. After the end, balance with an appropriate amount of purified water to prepare for the next separation.

Embodiment 2

[0040] The present embodiment reduces the content of camphor in borneol water by the following methods:

[0041] Take 40mL resin Diaion HP21, equilibrate the column with an appropriate amount of purified water, and wash the resin. Then 640 mL of borneol water was loaded into the sample. The flow rate is 2.5 times the column volume per hour, collect the sample effluent, and perform GC detection; after collecting the sample effluent, take 40mL of 90% ethanol solution, and the flow rate is 2 times the column volume per hour for column cleaning. After the end, balance with an appropriate amount of purified water to prepare for the next separation.

Embodiment 3

[0043] The present embodiment reduces the content of camphor in borneol water by the following methods:

[0044] Take 40mL resin Diaion HP20, equilibrate the column with an appropriate amount of purified water, and wash the resin. Then 280 mL of borneol water was loaded into the sample. At a flow rate of 1.5 times the column volume per hour, collect the sample effluent and perform GC detection; after collecting the sample effluent, take 80 mL of 90% ethanol solution at a flow rate of 2 times the column volume per hour for column cleaning. After the end, balance with an appropriate amount of purified water to prepare for the next separation.

Abstract

The invention provides a method for reducing the content of camphor in borneol water. The method comprises the following steps of: (1) loading a column separation filler into a column, and then loading a borneol water sample; and (2) collecting borneol water effluent to obtain borneol water with a reduced camphor content. The method provided by the invention has high safety, the camphor content ofthe borneol water treated by the method is obviously reduced, and unpleasant and irritant odor is obviously reduced, so that the borneol water has a wider application prospect and a higher application value.

Description

technical field [0001] The invention belongs to the field of natural product separation and relates to a method for reducing camphor content in borneol water. Background technique [0002] The method for extracting natural borneol (D-borneol) from borneol camphor, mostly adopts steam distillation-cooling crystallization method, and the water liquid after crystallization also contains a small amount of borneol etc. up to more than 21 kinds of components. The water liquid after crystallization (hereinafter referred to as "borneol water") contains a small amount of camphor and some unpleasant or irritating odors, which limits the application of borneol water to a certain extent. A large amount of borneol water after distillation cannot be rationally utilized, resulting in a waste of resources. [0003] There is almost no basic research on borneol water at present, and CN101422416B only expands the basic application of borneol water in the daily chemical field. Camphor has cer...
