Problems solved by technology

As for the rapid analysis method of the components in Gardenia, the current reports are the determination of non-volatile components such as geniposide (such as literature: Near-infrared spectroscopy to quickly determine the content of geniposide in the countercurrent extraction process of Gardenia, Journal of Nanjing University of Traditional Chinese Medicine , 2014, 30(1), 72-75), there is no literature report on the rapid analysis method of volatile components in gardenia

Embodiment 1

[0037] A kind of method based on ultraviolet spectrum rapid measurement turmeric-gardenia steam distillation extraction process multiple component content, the method comprises the following steps:

[0038] (1) Collection of samples

[0039]Crush and sieve turmeric and gardenia medicinal materials to 20-80 mesh respectively, take 30g of powder and mix evenly, add 1500mL of distilled water, soak for 12 hours, and extract by steam distillation. When the medicinal solution boils, start timing, take 5mL samples of the distillate at the outlet of the condenser at the 15th and 30th minutes respectively, and then sample 5mL every 30 minutes, and stop sampling when the total volume of the distillate (including the sampling volume) reaches 1000mL . According to the above conditions, 11 batches of extraction experiments were carried out, and the obtained samples were used as the training set.

[0040] After changing one of the above extraction conditions, five batches of extraction ex...

Embodiment 2

[0068] A kind of method based on ultraviolet spectrum rapid measurement turmeric-gardenia steam distillation extraction process multiple component content, the method comprises the following steps:

[0069] (1) Collection of samples

[0070] (2) Determination of the content of each component in the sample set

[0071] (3) Sample ultraviolet spectrum collection

[0072] (4) Establishment of quantitative calibration model

[0073] (5) Application of quantitative calibration model

[0074] Completed step (1)~(4) in the development process of the inventive method, concrete process can refer to embodiment 1 step (1)~(4), therefore, in the application of the inventive method, can directly carry out step ( 5) As follows: the medicinal materials of turmeric and gardenia are crushed and sieved to 10-20 meshes respectively, 30g of powders are taken and mixed evenly, add 1500mL of distilled water, soak for 12 hours, extract by steam distillation, wait for the liquid to boil, start Ti...

Abstract

The invention discloses a method for rapidly testing multiple component contents in a radix curcumae-jasmine steam distillation and extracting process based on an ultraviolet spectrum. Based on the ultraviolet spectrum and a multielement quantified correcting model, the rapidly, exactly and low-cost test the contents of isophorone, 4- methylene- isophorone, curcuma zedoary bicyclo- ketene, curcumazedoary enol, curcuma zedoary diketone, curcuma zedoary ketone, curcuma zedoary furanodienone, curcuma zedoary alcohol and germacrone in the radix curcumae-jasmine steam distillation and extracting process. The method is simple in operation, rapid in analysis, low in analysis cost, and free from damaging samples and consuming chemical reagents, and others. The method can be applied to the production process monitoring and quality control of Chinese material medical preparation (such as consciousness restoring injection) during the radix curcumae-jasmine steam distillation and extracting process.

Description

technical field [0001] The invention belongs to the field of analysis of the production process of traditional Chinese medicines, and in particular relates to a method for rapidly measuring the contents of various components in the steam distillation extraction process of turmeric-gardenia jasminoides. Background technique [0002] Curcuma (Radix Curcumae) tastes pungent, bitter, and cold in nature. It has the effects of promoting qi and removing blood stasis, clearing heart and relieving stagnation, promoting gallbladder and reducing jaundice, and the volatile components of sesquiterpenoids are important active ingredients. Fructus Gardeniae (Fructus Gardeniae) is bitter in taste and cold in nature. It has the functions of purging fire and relieving restlessness, clearing heat and promoting dampness, cooling blood and detoxifying, and its volatile components are considered as important medicinal substances. The two traditional Chinese medicines of turmeric and gardenia are ...
