Distribution of phenolic compounds and antioxidative activities of rice kernel and their relationships with agronomic practice.

The phenolic and antioxidant activity of ethanolic extract of two Japonica rice cultivars, Taikeng no. 16 (medium and slender grain) and Kaohsiung no. 139 (short and round grain), grown under organic and conventional farming were examined.

Isatis indigotica induces hepatocellular cancer cell death via caspase-independent apoptosis-inducing factor translocation apoptotic pathway in vitro and in vivo.

Isatis indigotica is a biennial herbaceous cruciferous medical herb with antipyretic, antiviral, anti-inflammatory, and anti-endotoxin activity. This study explored the chemotherapeutic potential of I indigotica on human hepatoma cells and investigated the mechanism by which metabolites from I indigotica inhibit hepatoma cell growth. Antitumor activity was discovered in dried I indigotica leaf chloroform extracts (CEDLI).

The cytotoxicity to leukemia cells and antiviral effects of Isatis indigotica extracts on pseudorabies virus.

Aim Of The Study: Isatis indigotica (I. indigotica), Cruciferae, has been used in Chinese medicine for anti-leukemia and anti-severe acute respiratory syndrome (SARS). The aim of this study was to evaluate the cytotoxicity of Isatis indigotica extracts on human leukemia cell line (HL-60) and the antiviral activity on swine pseudorabies virus (PrV) in in vitro assays.

LC-APCI-MS method for detection and analysis of tryptanthrin, indigo, and indirubin in daqingye and banlangen.

A rapid, selective, and sensitive LC-APCI-MS method is developed in this study for detecting and analyzing tryptanthrin, indigo, and indirubin in daqingye and banlangen, which are, respectively, the leaves and roots of Isatis indigotica and Strobilanthes cusia in traditional Chinese medicine. The detection of the three active components is linear in concentrations ranging from 100 to 1500 ng/mL, the squared correlation coefficient is higher than 0.996, the precision as measured by the relative standard deviation is no larger than 9.
