Columbin具有多種藥理活性，包括體內抗炎和抗腫瘤活性，此實驗中動物研究通過hjc黄金城進行

Columbin is an important component isolated from Radix Tinosporae. Columbin possesses many pharmacological activities, including anti-inflammation, and antitumor activity in vivo. The purpose of the present study was to examine in vivo pharmacokinetics and bioavailability of Columbin in rats using a high-performance liquid chromatography coupled with tandem mass spectrometry quantitative detection method. This is the first study demonstrating the bioanalytical method and pharmacokinetic of Columbin. Animal studies were carried out in Medicilon.
