Method: The contents of geniposide and crocetin Ⅰ was were determined by HPLC, the content of total iridoid glycosides was determined by ultraviolet spectrophotometry, and three index components in different parts of G. jasminoides were analyzed. HPLC fingerprints of different parts of G. jasminoides were collected, the common pattern of HPLC fingerprints of different parts of G. jasminoides of different origins and with different processing methods was established, and the similarity evaluation software was used for data analysis; comparative analysis on fingerprints of different parts of G. jasminoides was conducted. Result: Content change of index components in G. jasminoides pericarp and seeds from Henan, Fujian and Jiangxi were the same. Content of geniposide:Fujian > Henan > Jiangxi, the contents of three components in G. jasminoides pericarp from Fujian were much higher than those from Henan and Jiangxi, the contents of crocetin Ⅰ and total iridoid glycosides:Fujian > Jiangxi > Henan, the contents of total iridoid glycosides from Fujian, Jiangxi were much higher than those from Henan. The order of three index components in G. jasminoides whiskers from different origins from high to low, the content of geniposide and crocetin Ⅰ was Fujian > Jiangxi and Henan, the content of total iridoid glycosides was Fujian > Jiangxi > Henan.In the same part, there were 22 common peaks in the fingerprints of G. jasminoides pericarp, except for S13-S15, the similarity of other samples were more than 0.9;the fingerprints of G. jasminoides seeds had 22 common peaks, except for S22-S30, the similarities of other samples were more than 0.9;the fingerprints of G. jasminoides whiskers had 16 common peaks, except for S7-S9, the similarities of other samples were more than 0.9.In different parts, the fingerprints of G. jasminoides whiskers were significant different from those of pericarp and seeds, the number of peaks in G. jasminoides whiskers reduced, the order of height of peaks 2, 3, 5 of G. jasminoides from high to low were whiskers > gardenia > seeds. There was not peak X in the seeds, the height of peak X of gardenia in whiskers was higher than that in pericarp, except for the peak 17, the height of all peaks in seeds were higher than that in whiskers. Conclusion: There are significant differences in the contents of index components in G. jasminoides pericarp and seeds. The content of total glycosides in gardenia is high, suggesting that it can be used to extract total iridoid glycosides. The fingerprints can reflect the content difference and species distribution of different parts of G. jasminoides, so as to provide theoretical support for the studies for pharmacodynamic material basis of G. jasminoides and the scientificity and rationality of the separate application of G. jasminoides pericarp and seeds.
ABSTRACT
Objective: To discuss the phenotypic character and the HPLC fingerprints of radial striations from different germplasms Rehmanniae Radix. Method: The changes in the shape and column diameter of the radial striations of Rehmanniae Radix were observed and measured in the whole growth period. Besides,the HPLC fingerprints of the root,radial and un-radial striations were established to sign the chemical quality and analyzed by principal component analysis(PCA)and systematic cluster analysis. Result: There were significantly differences and regularities in the shape and proportion of the radial striations of different germplasms Rehmanniae Radix. The fingerprints showed the consistency between different types of chemical ingredients,and the differences in chemical quality characteristics mainly lay in the content of chemical compositions and theirs relative ratio. The results of PCA indicated that active ingredients, such as acteoside,catalpol,rehmaionoside D,rehmaionoside A and leonuride, were involved in the quality expression of different parts from various germplasms of Rehmanniae Radix,but each ingredient had a distinctive contribution rate to the differential quality expression between different parts from various germplasms of Rehmanniae Radix. However,the other components involved in the differential quality expression had different contribution rates in different germplasms.The systematic cluster analysis indicated that great differences in the chemical quality between the radial striations and un-radial striations of Beijing-1,Qinhuai,Qinhuai Zheng and 1706 germplasms,but with small differences in 85-5 and Baixuan germplasms. Conclusion: There are differences in phenotypic character of the radial striations and HPLC fingerprints between different germplasms Rehmanniae Radix.

ABSTRACT
To investigate the effect of different initial processing methods on the quality of Gardenia and determine the best cooking time in gardenia processing through the determination of index components content. The contents of geniposide, crocetin Ⅰ and total iridoid glycosides in Gardenia were determined before storage, six months after storage and one year after storage. During storage, the contents of geniposide, crocetin Ⅰ and total iridoid glycosides in directly dried Gardenia were 1.68%, 0.45% and 6.45% respectively. The contents of geniposide, crocetin Ⅰ and total iridoid glycosides in Gardenia with different steaming time were 1.34%-0.5%, 0.28%-0.06% and 6.09%-1.59% respectively. The contents of geniposide, crocetin Ⅰ and total iridoid glycosides in Gardenia with different boiling time (adding alum)were 1.42%-0.41%, 0.35%-0.07% and 6.40%-1.65% respectively. The direct drying of Gardenia samples could not achieve the function of killing enzyme and protecting glycosides. The enzymes from degradation of the index components were basically destroyed after steaming time of 13 min or boiling (adding alum) time of 8 min, achieving the function of killing enzyme and protecting glycosides.
