Composition changes and the characterization of “fried charcoal and saving properties” based on the carbon-frying process of Sophora japonica and its bud
To explore the changes in chemical compositions and the characteristics of “fried charcoal and saving properties” based on the carbon-frying process of
Sophora japonica
and its bud.
METHODS
2
The slightly, moderately and heavily carbon-fried samples of
S. japonica
and its bud were prepared. The fingerprints of
S. japonica
, its bud and carbon-fried samples were established, and common peaks were identified. HPLC method was used to determine the contents of identified components and differential analysis was also performed; the differential components were screened by using chemometric methods, and their content ratios were used to characterize the “fried charcoal and saving properties” of
S. japonica
and its bud.
RESULTS
2
There were 9 common peaks in the fingerprints of
S. japonica
and its carbon-fried samples, 8 common peaks in those of
S. japonica
bud and its carbon-fried samples. In the fingerprints of
S. japonica
and its bud, and their different fried products, 6 components were identified, such as rutin, kaempferol-3-
O
-rutinoside, isorhamnetin-3-
O
-rutinoside, quercetin, kaempferol, isorhamnetin. Among them, the contents of rutin, kaempferol-3-
O
-rutinoside and isorhamnetin-3-
O
-rutinoside were the highest in slightly carbon-fried samples of
S. japonica
bud, and the contents of quercetin and isorhamnetin were the highest in moderately carbon-fried samples of
S. japonica
bud, and the contents of kaempferol were higher in moderately and healily carbon-fried samples of
S. japonica
bud. The chemometric results showed that the variable importance projection values of rutin
and quercetin were both greater than 1. The range of rutin-quercetin content ratio between 9.00-14.00 and 3.00-6.00 respectively could characterize “fried charcoal and saving properties” of
S. japonica
and its bud.
CONCLUSIONS
2
There are significant differences in the chemical compositions of raw and fried products of
S. japonica
and its bud. Rutin and quercetin may be the differential components that affect their quality, and the ratio range of the two can be used to characterize the “fried charcoal and saving properties” of
S. japonica
and its bud in the future.
