ABSTRACT

To standardize the processing technology of Polygoni Multiflori Radix Praeparata and stabilize its quality, the similar change laws of Polygoni Multiflori Radix Praeparata with different processing methods and time were analyzed. The processing time of Polygoni Multiflori Radix Praeparata was studied at 24, 32, 40, 48 h, and 4 different processing methods were studied, namely stewed with black bean sauce, steamed, steamed with black bean sauce, and steamed with black bean sauce and rice wine. The content of stilbene glycosides and anthraquinones were determined by HPLC-DAD method. UV method was used to determine the content of polysaccharides, and HPLC-ELSD method was used to determine the monosaccharides and oligosaccharides. The comparative chart of content determination, cluster analysis and entropy weight TOPSIS model was used to find the similar change laws and time interval of different processing methods of Polygoni Multiflori Radix Praeparata. The results demonstrated that around 32 h, the content of nine components in Polygoni Multiflori Radix Praeparata with different processing methods had similar change laws, and the decoction pieces had a high quality, indicating that the four processing methods of Polygoni Multiflori Radix Praeparata are likely to be used as one type of decoction piece with the same name.

ABSTRACT

Objective::To investigate the effects of black bean juice with different stewing times on the appearance character and the content changes of effective components of Polygoni Multiflori Radix Praeparata. Method::HPLC was employed with Agilent ZORBAX Extend-C18 column (4.6 mm×250 mm, 5 μm), a gradient mobile phase of methanol (A)-water (B) was eluted (0-30 min, 5%-100%A; 30-40 min, 100%A), the flow rate was 1.0 mL·min-1, the injection volume was 10 μL and the column temperature was 35 ℃, detection wavelength was set at 280 nm. The contents of stilbene glycoside, emodin, emodin methyl ether, emodin-8-O-β-D-glucoside and emodin methyl ether-8-O-glucoside in samples prepared at different processing times were simultaneously determined by HPLC. Result::The content of stilbene glycoside decreased gradually with the increase of stewing time, compared with 8 h, its content decreased by 76% at 64 h. The contents of emodin-8-O-β-D-glucoside and emodin methyl ether-8-O-glucoside increased first, and then decreased, reaching the highest value at 24 h, and then decreased to the level similar to the content of 8 h after 40 h, and then fluctuated slightly. The contents of emodin and emodin methyl ether increased first, and then decreased, reached the maximum when stewed for 32 h, then decreased slowly and tended to be stable. Conclusion::The stewing time has significant influence on the content of various components in Polygoni Multiflori Radix Praeparata, and the changing trend is different, the processing time of Polygoni Multiflori Radix Praeparata shall be standardized. At the same time, it is not sufficient to take stilbene glycoside and anthraquinones as the indicator ingredients for this decoction pieces, the quality control indicators such as polysaccharides shall be considered.

ABSTRACT

Objective: Based on the color space technology of CIE-LAB,the color of vinegar-processed Corydalis Rhizoma decoction pieces was digitized,combining with the contents of 10 major alkaloids in the decoction pieces,to discuss the correlation between the color and contents of main ingredients of vinegar-processed Corydalis Rhizoma decoction pieces,and investigate the intrinsic quality difference in the decoction pieces with different color. Method: The precision colorimeter was used to determine the color parameters of vinegar-processed Corydalis Rhizoma decoction pieces;HPLC was employed to determine contents of main chemical components in the decoction pieces,which was performed on Agilent ZORBAX SB-C18 column(4.6 mm×250 mm,5 μm) with mobile phase of acetonitrile(A)-0.1% potassium dihydrogen phosphate aqueous solution(B) for gradient elution(0-10 min,5%-22%A;10-30 min,22%-25%A;30-50 min,25%-60%A;50-70 min,60%-95%A),detection wavelength of 280 nm,column temperature at 30℃ and flow rate of 1.0 mL·min-1. Result: The quality of vinegar-processed Corydalis Rhizoma decoction pieces with different color was in line with the requirement of the 2015 edition of Chinese Pharmacopoeia,but there were differences in the intrinsic quality between the decoction pieces.The total content of chemical components in the samples showed a positive correlation with the a*(green-red axis) and total chromatic aberration value(ΔE) in the CIE-LAB color space, and it was significantly negative correlated with L*(lightness) and b*(blue-yellow axis).In the 10 tested components,except for D-tetrahydrojatrorrhizine and tetrahydrocoptisine,contents of protopine and other 6 components were positively correlated with color,and only the content of corydaline was negatively correlated with color. Conclusion: Color analysis technology can objectively quantify the color of the decoction pieces,and can achieve a quick evaluation of quality of the decoction pieces by analyzing correlation between the color and the contents of main active ingredients.

ABSTRACT

Objective:To elucidate the characteristics of bidirectional regulation of raw and steamed products of Rhei Radix et Rhizoma and their active components, in order to provide scientific basis for clinical rational use of this decoction pieces. Method:Mice were randomly divided into the blank group(distilled water, 10 mL·kg-1), raw rhubarb group(1.62 g·kg-1), steamed rhubarb group(0.972 g·kg-1), raw rhubarb anthraquinone group(0.22 g·kg-1), steamed rhubarb anthraquinone group(0.19 g·kg-1), raw rhubarb tannin group(0.17 g·kg-1) and steamed rhubarb tannin group(0.027 g·kg-1). Each group was divided into 3 batches of 10 mice. Mice in each group were given the corresponding dose by continuous gavage for 7 days, the diarrhea index(EI) of mice in each group was recorded every day. The serum levels of motilin(MTL), vasoactive intestinal peptide(VIP) and epinephrine(EPI) were measured on day 1,3,7. Result:Compared with the blank group, EI of the rhubarb group increased significantly on the 3rd day(Pth day of administration(Prd day(Pth day(Pst day of administration, on the 3rd day of administration, the MTL level in the steamed rhubarb anthraquinone group increased significantly(PPPth day of administration, the MTL levels of the raw and steamed rhubarb tannin groups increased to the level in the blank group, the VIP level of the raw rhubarb anthraquinone group increased significantly(PPConclusion:The combined anthraquinone and hydrolyzable tannin in rhubarb can promote gastrointestinal motility and diarrhea. The effect of astringent intestines is caused by the monomer tannin produced by digestion and decomposition of condensed tannin, which may be one of the mechanisms of bidirectional regulation of rhubarb decoction pieces.

ABSTRACT

In recent years, in order to further improve the quality of decoction pieces of Chinese crude drugs, many related basic research work around the processing of decoction pieces of Chinese crude drugs have been carried out by relevant experts. Many opinions and suggestions on the revision of the National Regulations on the Processing of Decoction Pieces of Chinese Crude Drugs were put forward. In order to further improve the preparation of the National Regulations on the Processing of Decoction Pieces of Chinese Crude Drugs, strengthen the guidance on the revision of local processing standards, and clarify issues related to the circulation, use and supervision of decoction pieces, the Department of Drug Registration Management of the National Medical Products Administration and the Chinese Pharmacopoeia Commission have organized experts to discuss these problems. The author only puts forward some suggestions on related issues in order to achieve the purpose of "throwing a brick to attract jade". ①The study of the national regulations on the processing of decoction pieces of Chinese crude drugs should be standardized on the basis of the inheritance for the specific process. ②The revision of the National Regulations on the Processing of Decoction Pieces of Chinese Crude Drugs should be improved on the basis of the existing research results. The regulation of the processing process should not be excessively parameterized, the revision of the National Regulations on the Processing of Decoction Pieces of Chinese Crude Drugs also should be synchronization to the revision of the Chinese Pharmacopoeia. ③The contents of the Chinese Pharmacopoeia and the National Regulations on the Processing of Decoction Pieces of Chinese Crude Drugs should have different emphasis. The former should focus on the standard, while the latter should focus on the processing process. ④The revision of local (provincial) processing specifications only collects the pieces that truly have local features and clinical characteristics. ⑤Decoction pieces of local Chinese crude drugs can only be applied at the place of production (province). They are allowed to be produced and distributed in other provinces, municipalities and autonomous regions after through filing. ⑥For the decoction pieces of Chinese crude drugs with large-scale use contained in local processing specifications, they should be included in the National Regulations on the Processing of Decoction Pieces of Chinese Crude Drugs as soon as possible, and their quality standards should be included in the Chinese Pharmacopoeia.
