Qi-Dan Fang ameliorates adriamycin-induced nephrotic syndrome rat model by enhancing renal function and inhibiting podocyte injury.

Ethnopharmacological Relevance: Nephrotic syndrome (NS) is a clinical syndrome with a variety of causes, mainly characterized by heavy proteinuria. Podocyte injury plays a key role in proteinuria, one of the principal means for the control of NS is to prevent podocyte injury. Qi-Dan Fang consists of two of the most extensively applied herbal remedies among Traditional Chinese Medicine (TCM) (Radix Astragali Mongolici and Radix Salviae Miltiorrhizae, with a weight ratio of 5:1) which are specifically used for the treatment of various kidney diseases.

Optimisation of infrared-assisted extraction of rutin from crude Flos Sophorae Immaturus using response surface methodology and HPLC analysis.

Introduction: Rutin, one of main constituents in Flos Sophorae Immaturus, has been proven to possess several pharmacological properties such as anti-oxidant, anti-platelet, anti-inflammatory effects and so on. However, optimisation of the extraction of rutin from Flos Sophorae Immaturus has rarely been reported. Thus, it is important to develop an effective method to obtain maximum yields of rutin from Flos Sophorae Immaturus.

Improved liquid chromatography fingerprint of fat-soluble Radix isatidis extract using multi-wavelength combination technique.

We first investigated liquid chromatography (LC) fingerprint method using multi-wavelength combination technique, and successfully used this method for the analysis of a fat-soluble extract from Radix isatidis. LC fingerprints of fat-soluble R. isatidis extracts from 11 origins were established using the Origin software and Similarity Evaluation System for Chromatographic Fingerprints of traditional Chinese medicine (TCM).
