RESUMO
Curcumin (CCM) is a polyphenol compound extracted from the turmeric rhizome. It has various biological activities, including antibacterial, anti-inflammatory, anti-cancer, and antioxidant. Due to its diverse activities, it is often used by researchers to study the therapeutic effects on various diseases. However, its poor solubility leads to poor bioavailability, and it is necessary to increase the water solubility with the help of carriers to improve the therapeutic effect. Gastrointestinal disease is a major global health problem that continues to affect human health. In this review, we have summarized the possible mechanism and therapeutic effect of CCM in various gastrointestinal diseases, and the improvement in the curative effect of CCM with nanopreparation. Finally, we concluded that there have been many clinical trials of CCM in combination with other drugs for the treatment of gastrointestinal disease, but so far, few have used CCM nanomaterials for treatment. Although in vitro and preclinical experiments have shown that nanopreparations can improve the efficacy of CCM, there are still insufficient studies on the safety of carriers.

To establish a content determination method for quality control of the pieces and standard decoction of honey-fried Descurainiae Semen. Standard decoction of honey-fried Descurainiae Semen was prepared with standardized process, and high performance liquid chromatography coupled with diode-array detector(HPLC-DAD) was used to detect its characteristic fingerprint and determine the content of quercetin-3-O-ß-D-glucose-7-O-ß-D-gentiobioside. In addition, the transfer rate, dry extract rate and pH value were calculated. The results showed that the established method had a high accuracy. The content of quercetin-3-O-ß-D-glucose-7-O-ß-D-gentiobioside in 13 batches of standard decoction was 0.03-0.12 mg·mL~(-1); the transfer rate was 13.4%-23.1%; the rate of extracts was 1.9%-5.5%, and the pH was between 5.4-5.9. The similarity coefficients were all greater than 0.85, indicating good homogeneity for the different batches of decoction. There were 7 common peaks in the characteristic chromatogram, one of which was quercetin-3-O-ß-D-glucose-7-O-ß-D-gentiobioside. In this paper, the established content determination and quality evaluation method for Descurainiae Semen pieces and decoction was simple, rapid and reproducible, providing reference for the quality control of honey-fried Descurainiae Semen pieces, standard decoction and its preparations.
