Abstract

Ailanthus altissima (AA) has been used in various anticancer prescriptions and showed excellent therapeutic effect. However, there is no report on the method of quality control and the anti-glioblastoma activity. In this study, we used a combinative method approach consisting of chromatographic fingerprinting and quantitative methods to analyze quality of different samples. The anti-glioblastoma activity and the possible mechanisms were studied by pharmacological methods. The samples were separated on a Kromasil 100-5 C18 column and the flow rate was 0.8 ml/min at 25˚C. The mobile phase was composed of 1% formic acid and 1% methanol-water at a flow rate of 0.8 ml/min. The method was validated and applied to the quantification of different samples. Ten batches of AA from different provinces in China were detected, and we found that the contents of Ailanthone (AT) ranged from 0.21-1.78 mg/g and the relative retention times were similar in different origins. Ten batches of AA were analyzed by the high-performance liquid chromatography (HPLC) fingerprinting method and 19 common peaks were detected. The similarity of 10 batches is <1.5%. The peak areas in different samples were significantly different (0.682-0.954). We also found th...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Apoptotic Caspases

Apoptotic caspases belong to the protease enzyme family and are known to play an essential role in inflammation and programmed cell death. Here is the latest research.
