Objective To establish a method for simultaneous determination of 14 components in Cinnamomi Cortex;To comprehensively evaluate its quality by multivariate statistical analysis technology.Methods HPLC method was used to establish the relative correction factors(RCF)between protocatechuic acid and 13 other components of coumalic acid,coumarin,cinnamyl alcohol,cinnamic acid,2-methoxycinnamic acid,cinnamaldehyde,o-methoxycinnamaldehyde,vanillic,syringic acid,4-hydroxybenzoic acid,procyanidin B2,epicatechin and procyanidin C1 to be measured,and the content of each component was calculated.The QAMS method was validated using external standard method(ESM),and the comprehensive quality of Cinnamomi Cortex was evaluated using PCA,OPLS-DA and EW-TOPSIS methods.Results The methodological verification results of ESM were in accordance with the requirements;the RCF established with protocatechuic acid as the reference had good durability under different experimental conditions,and the difference in content of each component between ESM and QAMS was not significant(P>0.05);the results of multivariate statistical analysis showed that accumulative contribution rate of former 2 principle components was 90.312%.Cinnamaldehyde,2-methoxycinnamic acid,procyanidin B2 and 4-hydroxybenzoic acid had a significant impact on the quality of Cinnamomi Cortex.The results of EW-TOPSIS showed that the Pi value of 16 batches of Cinnamomi Cortex ranged from 0.147 2 to 0.768 1.The quality of Cinnamomi Cortex from different producing areas varied greatly,and the overall quality of Cinnamomi Cortex from Guangxi Province was the best,followed by that from Guangdong Province and Yunnan Province,and the quality of Cinnamomi Cortex from Fujian Province was relatively poor.Conclusion The established QAMS multi-component quantitative method combined with multivariate statistical analysis technology can be used for comprehensive quality evaluation of Cinnamomi Cortex.

OBJECTIVE: To study the long-term toxicity of Liqi sanjie extractum in rats after intragastric administration, and to provide reference for safety evaluation before clinical practice. METHODS: A total of 160 rats were randomly divided into control group (normal saline) and Liqi sanjie extractum low-dose, medium-dose and high-dose groups (7.828 0, 15.656 0, 31.312 0 g/kg, calculated by crude drug), with 40 rats in each group. They were given relevant medicine intragastrically once a day from Monday to Saturday. The experimental period was 120 days, and the recovery period was 30 days after the end of the experiment. General information of rats was observed, and body weight and feed consumption of rats were measured once a week. At the 61st day of administration, the end of administration and the end of recovery period, 10, 20 and 10 rats were collected from each group to observe their hematology, blood biochemistry, organ coefficient and histopathology changes. RESULTS: From 61st day to 120th day of administration, the rats of Liqi sanjie extractum high-dose group had hair loss and erection, and recovered after withdrawal of medicine. During medication, the body weight of mice in Liqi sanjie extractum low-dose and medium-dose groups increased faster than control group, while the body weight of rats in Liqi sanjie extractum high-dose group increased slower than control group. Compared with control group, the feed consumption of Liqi sanjie extractum low-dose group increased, while those of Liqi sanjie extractum medium-dose and high-dose groups decreased; the rats were recovered after drug withdrawal. On the 61st day of administration and after the end of administration, some hematological indexes, blood biochemical indexes and organ coefficients of rats in administration group were significantly different from those of control group (P<0.05 or P<0.01). The hematology, blood biochemistry and organ coefficients of rats were basically recovered after the end of the recovery period. The number of erythrocyte, hematocrit, standard deviation of erythrocyte width, albumin, globulin ratio and potassium K+ levels in Liqi sanjie extractum low-dose group were significantly lower than those in control group (P<0.05 or P<0.01). The absolute value of intermediate cells in blood of rats in Liqi sanjie extractum medium-dose group was significantly higher than that of control group (P<0.05), and the mean hemoglobin concentration, K+ and uterine coefficient in blood were significantly lower than those of control group (P<0.05). The number of white blood cells, absolute value of lymphocyte, absolute value of intermediate cells, the percentage of intermediate cells, prothrombin time and spleen coefficient in Liqi sanjie extractum high-dose group were significantly higher than those in the control group (P<0.05 or P<0.01). Mean hemoglobin concentration, granulocyte percentage, albumin, alkaline phosphatase and K+ were significantly lower than those in the control group (P<0.05 or P<0.01). No abnormalities in systemic autopsy and histopathology were noticed in rats. CONCLUSIONS: Long-term intragastric administration of Liqi sanjie extractum can cause certain toxic reactions in rats, and low dose of Liqi sanjie extractum causes less and lighter toxic reactions which can be automatically recovered after drug withdrawal. It can provide reference for the determination of clinical safe dose.

OBJECTIVE: To investigate the improvement effects of Liqi sanjie granule on liver-qi stagnation model rats. METHODS: According to the weight, totally 80 rats were randomly divided into blank control group (normal saline), model control group (normal saline), Xiaoyao pill control group (positive control a, 750 mg/kg ,calculated by crude drug), Xiaojin pill control group (positive control b, 200 mg/kg, calculated by pill weight), Liqi sanjie pill control group (prototype control, 1 957 mg, calculated by crude drug) and Liqi sanjie granule low-dose, medium-dose and high-dose groups (978.5, 1 957, 3 914 mg/kg, calculated by crude drug), with 10 rats in each group. Each group was given medicine 20 mL/kg intragastrically once a day, for consecutive 21 d. 1 h after per medication, liver-qi stagnation model was established in those groups by binding method except for blank control group. The syrup preference of rats was determined by designing syrup preference test. Rattail suspension test was adopted to determine the hanging immobility time and struggling times of mice. Open-field behavior test was used to determine total behavior score so as to judge the extent of liver-qi stagnation and effect of the drug in rats. RESULTS: Compared with blank control group, hanging immobility time of model control group was significantly prolonged, the syrup preference and the total behavior score of open field test were decreased significantly, with statistical significance (P<0.05 or P<0.01). Compared with model control group, the struggling times of rats were increased significantly in Xiaojin pill control group, Liqi sanjie pill control group and Liqi sanjie granule medium-dose group (P<0.05 or P<0.01); the hanging immobility time of Xiaoyao pill control group, Xiaojin pill control group, Liqi sanjie pill control group, Liqi sanjie granule low-dose and medium-dose groups were shortened significantly; syrup preference and total behavior score of open-field behavior test were increased significantly (P<0.05 or P<0.01). Compared with Liqi sanjie pill control group, the struggling times of rats were decreased significantly and hanging immobility time were prolonged significantly only in Liqi sanjie granule high-dose group (P<0.05 or P<0.01); there was no statistical significance in above indexes of rats in Liqi sanjie granule low-dose and medium-dose groups (P>0.05). CONCLUSIONS: Liqi sanjie granule can significantly improve liver-qi stagnation caused by binding method, and the effects of low-dose and medium-dose Liqi sanjie granule are similar to those of Liqi sanjie pill.
