Study on the contents of five active components and fingerprint of Gardenia jasminoides-Scutellaria baicalensis herb pairsbefore and after processing
To establish the method for determining the contents of five active components in raw and charred herb pairs of
Gardenia jasminoides-Scutellaria baicalensis
, construct their fingerprints, and investigate the effects of
G. jasminoides
processing on chemical constituents in the h
erb pairs.
METHODS
2
The HPLC method was used to determine the contents of genipin 1-
β
-D-gentiobioside, geniposide, crocin Ⅰ, crocin Ⅱ and baicalin in ten batches of raw
G. jasminoides-S. baicalensis
herb pairs and ten batches of charred
G. jasminoides-S. baicalensis
herb pairs. Using the same HPLC method, chromatographic fingerprints for the ten batches of raw herb pairs and ten batches of processed herb pairs were established with the
Similarity Evaluation System for Chromatographic Fingerprints of Traditional Chinese Medicine
(2012 edition). Principal component analysis and orthogonal partial least squares-discriminant analysis were performed.
RESULTS
2
Compared with the raw
G. jasminoides-S. baicalensis
herb pair, the average content of genipin 1-
β
-D-gentiobioside in the charred
G. jasminoides-S. baicalensis
herb pair increased by 12.65%; while the average contents of geniposide, crocin Ⅰ, crocin Ⅱ and baicalin decreased by 7.86%, 60.62%, 62.07% and 0.15%, respectively. Chromatographic fingerprints of ten batches of raw herb pairs and ten batches of processed herb pairs shared 18 common peaks with similarities ranging from 0.997 to 1.000 and 0.988 to 1.000, respectively. Five common peaks were identified: genipin 1-
β
-D-gentiobioside (peak 2), geniposide (peak 3), crocin Ⅰ (peak 6), crocin Ⅱ (peak 9) and baicalin (peak 10). Principal component analysis and orthogonal partial least squares-discriminant analysis results showed that the raw
G. jasminoides-S. baicalensis
herb pair and the charred
G. jasminoides-S. baicalensis
herb pair could be clearly distinguished. Variable importance in the projection (VIP) values for crocin Ⅰ and crocin Ⅱ were both greater than one.
CONCLUSIONS
2
A method has been successfully developed for the determination of five active c
omponents, including genipin 1-
β
-D-gentiobioside, in the
G. jasminoides-S. baicalensis
herb pair, and its fingerprint has been drawn. Processing is found to increase the content of genipin 1-
β
-D-gentiobioside, while decreasing the levels of geniposide, crocin Ⅰ, crocin Ⅱ and baicalin in the herb pair. Furthermore, crocin Ⅰ and crocin Ⅱ could serve as potential quality markers for the quality control of this herb pair.
