RESUMEN
This study aimed to investigate the impact of ginger juice on chemical profile of Magnoliae Officinalis Cortex(MOC) when they were processed together. Ultra-high-performance liquid chromatography coupled to quadrupole-orbitrap high-resolution mass spectrometry(UHPLC-Q-Orbitrap HRMS) was used for qualitative analysis of the chemical component of MOC samples before and after being processed with ginger juice. UPLC was performed to observe the content variation of eight main components in processed MOC. A total of 174 compounds were identified or tentatively deduced from processed and unprocessed MOC samples according to MS data obtained in positive and negative ion mode. After MOC was processed with ginger juice, the peak areas of most phenolics increased, while the peak areas of most phenylethanoid glycosides decreased; as for neolignans, oxyneolignans, other lignans and alkaloids, changes in the peak area were variable, and the peak areas of terpenoid-lignans varied little. Additionally, gingerols and diarylheptanoids were only detected in the processed MOC sample. The contents of syringin, magnoloside A, and magnoloside B decreased significantly in the processed MOC sample while no significant difference was observed in the contents of magnoflorine, magnocurarine, honokiol, obovatol, and magnolol. This study comprehensively explored the content variation of chemical components in processed and unprocessed MOC samples derived from different regions and with different tree ages using UPLC and UHPLC-Q-Orbitrap HRMS, and summarized the variation characteristics of various compounds. The results provide a data foundation for further research on pharmacodynamic substances of MOC processed with ginger juice.

The weight coefficients of appearance traits, extract yield of standard decoction, and total content of honokiol and magnolol were determined by analytic hierarchy process(AHP), criteria importance though intercrieria correlation(CRITIC), and AHP-CRITIC weighting method, and the comprehensive scores were calculated. The effects of ginger juice dosage, moistening time, proces-sing temperature, and processing time on the quality of Magnoliae Officinalis Cortex(MOC) were investigated, and Box-Behnken design was employed to optimize the process parameters. To reveal the processing mechanism, MOC, ginger juice-processed Magnoliae Officinalis Cortex(GMOC), and water-processed Magnoliae Officinalis Cortex(WMOC) were compared. The results showed that the weight coefficients of the appearance traits, extract yield of standard decoction, and total content of honokiol and magnolol determined by AHP-CRITIC weighting method were 0.134, 0.287, and 0.579, respectively. The optimal processing parameters of GMOC were ginger juice dosage of 8%, moistening time of 120 min, and processing at 100 ℃ for 7 min. The content of syringoside and magnolflorine in MOC decreased after processing, and the content of honokiol and magnolol followed the trend of GMOC>MOC>WMOC, which suggested that the change in clinical efficacy of MOC after processing was associated with the changes of chemical composition. The optimized processing technology is stable and feasible and provides references for the modern production and processing of MOC.

ObjectiveTo investigate the key compounds affecting the irritation and to clarify the effect of heating and the addition of ginger juice as the auxiliary material during the processing on the irritation of Magnoliae Officinalis Cortex(MOC) by comparing the irritation and composition of volatile oil in MOC and its different processed products. MethodVolatile oil in raw products, water-processed products, ginger-dried products, ginger-fried products(the amounts of ginger were 10%, 50%, respectively) of MOC were extracted by steam distillation and subjected to rabbit eye irritation experiment, and the volatile components of each sample were detected by gas chromatography-mass spectrometry(GC-MS). Principal component analysis(PCA)and orthogonal partial least squares-discriminant analysis(OPLS-DA) were used to analyze the data of each sample by SIMCA 14.1. The relative contents of different processed products were compared two by two with those of and raw products or ginger-fried products, and the markers that might be related to the irritation were sorted out according to the principles of variable importance in the projection(VIP) value >1 and P<0.05, and the factors influencing the differences in irritation were analyzed. ResultCompared with the blank group, the administration groups all had irritation to the eyes of rabbits, and the degree of irritation was in the order of raw products>water-processed products>ginger-dried products>ginger-fried products(10%)>ginger-fried products(50%). The results of PCA and OPLS-DA showed that there were differences in the volatile oil from raw products and different processed products. According to VIP value>1 and P<0.05, and combined with the results of eye irritation experiment, ten volatile compounds related to irritation changes were screened out. Among them, cis-cinnamaldehyde was only detected in raw products, the relative contents of β-caryophyllene, (+)-delta-cadinene, α-humulene, γ-muurolene, (-)-isoledene and citral all increased to different degrees, the contents of p-cymene, 1(10)-4-cadinadien-15-ol and β-eudesmol all decreased to different degrees. ConclusionThe irritation of MOC is reduced after heating and processing with ginger juice, and the synergistic effect of both is more effective for reducing irritation. Among the differential markers associated with changes in irritation, the increase in the relative content of citral is closely related to the addition of ginger juice, while the decrease in the relative contents of cis-cinnamaldehyde, p-cymene, 1(10)-4-cadinadien-15-ol is related to heating, and the changes of other components may be related to the synergistic effect of heating and ginger juice.
RESUMEN
Objective: To establish the grade evaluation standard for Magnoliae Officinalis Cortex processed with ginger juice by combining traditional morphology evaluation with modern intrinsic quality evaluation. Method: The morphological parameters and contents of intrinsic pharmacodynamic index components of 28 batches of Magnoliae Officinalis Cortex processed with ginger juice were determined, and the relative quality constants were calculated. Assuming that the average relative quality constant was 100%, more than 120%of the samples were classified as the first grade, 60%to 120%as the second grade, the remaining as the third grade. Result: The relative quality constant of Magnoliae Officinalis Cortex processed with ginger juice ranged from 0.09 to 1.78. The relative quality constant of the first grade was ≥ 0.64, the second grade was 0.32-0.64, while the third grade was ≤ 0.32. Conclusion: Relative quality constant combines external indexes of traditional morphology and internal indexes of pharmacodynamic components, which can objectively, reasonably and scientifically classify the grade of Magnoliae Officinalis Cortex processed with ginger juice, and provide reference for establishing and improving the grade evaluation standard of this decoction pieces.
RESUMEN
To optimize the technology of Gardeniae Fructus processed with ginger juice,establish fingerprints and simultaneously determine seven compounds( geniposidic acid,chlorogenic acid,genipin-1-β-D-gentiobioside,geniposide,rutin,crocin Ⅰ,and crocin Ⅱ) by using ultra high performance liquid chromatography( UPLC). Waters ACQUITY UPLC BEH C18( 2. 1 mm×50 mm,1. 7μm) column was used with acetonitrile and 0. 1% formic acid solution as mobile phase for gradient elution at the flow rate of 0. 4 m L·min-1. The data was comprehensively processed and analyzed with similarity evaluation,principal component analysis( PCA) and partial least squares discriminant analysis( PLS-DA) methods. Twenty common peaks were identified in this study,and the similarity of samples was over 0. 97. The results of PCA and PLS-DA showed that there were differences in chemical compositions and contents between the raw Gardeniae Fructus and those processed with ginger juice,with 9 potential differentiated chromatographic peaks. After being processed with ginger juice,the contents of chlorogenic acid,crocin Ⅰ and crocin Ⅱ were less than before and the contents of other four compositions were higher than before. The optimized preparation for Gardeniae Fructus processed with ginger juice was stable and feasible. The methods of UPLC fingerprints and simultaneous determination of seven components can be effectively carried out to distinguish Gardeniae Fructus and Gardeniae Fructus processed with ginger juice.
