Quality Evaluation of Polar and Active Components in Crude and Processed Fructus Corni by Quantitative Analysis of Multicomponents with Single Marker

الملخص EN

Objective.

To develop a quantitative analysis of multicomponents by single-marker (QAMS) method for the simultaneous determination of polar active components in Fructus Corni.

Methods.

Loganin was selected as the internal reference, and the relative correction factors (RCFs) of gallic acid, 5-hydroxymethyl-2-furfural, morroniside, sweroside, cornin, 7α-O-methylmorroniside, 7β-O-methylmorroniside, 7α-O-ethylmorroniside, 7β-O-ethylmorroniside, and cornuside were established.

The contents of multicomponents were then calculated based on their RCFs, respectively.

Contents of the 11 components were also calculated by external standard method and compared with those of the QAMS method.

Results.

The contents of the 11 components in 21 crude and 10 processed Fructus Corni products were measured.

No significant difference was found in the quantitative results of the QAMS and external standard methods.

Conclusion.

QAMS could serve as an accurate and convenient method in determining the polar and active components in Fructus Corni and its processed products.
