[Analysis of different dosage forms of Xiasangju granules on fingerprints and models using high performance liquid chromatography].

To establish the fingerprints of Xiasangju granules (with sugar and non-sugar forms) by HPLC, and provide reference for their identification and effective quality control. High performance liquid chromatography (HPLC) method was used to collect the fingerprints of 20 batches of non-sugar Xiasangju granules and 34 batches of sugar type Xiasangju granules. Their main different components were classified and screened by mode identification methods (principal component analysis, PCA, and orthogonal partial least squares discriminate analysis, OPLS-DA).

[UPLC Fingerprint of Oldenlandia corymbosa].

Objective: To establish the UPLC fingerprint of Oldenlandia corymbosa from different regions and to distinguish it from Oldenlandia diffusa.

Methods: UPLC procedure was performed on an ACQUITY UPLC BEH C18 (50 mm x 2. 1 mm, 1.
