Detail Information

The Brownlee SPP C18 column is a high purity column that exhibits excellent peak shapes for a wide range of compounds. This column is filled with 2.7 μm superficially porous particles that contain a 1.7 μm solid inner core and a 0.5 μm porous silica outer shell, allowing for a shorter diffusion path and nearly double the efficiency compared to traditional fully porous silica particles. It can be used to enhance the performance of both traditional HPLC systems and UHPLC systems and is compatible with 2 µm inlet frits, so traditional solvents and sample preparation techniques can be used. Specialized filters are not needed for UHPLC systems.

Analysis of Ginsenosides in Ginseng Root with the PerkinElmer Flexar FX-15 System Equipped with a PDA Detector

Ginseng has been used as an herbal medicine in Asia for over two thousand years for its purported various health benefits, including antioxidant, anticarcinogenic, antiinflammatory, antihypertensive and anti-diabetic. The pharmacologically active compounds behind the claims of ginseng’s efficacy are ginsenosides; their underlying mechanism of action although not entirely elucidated appears to be similar to that of steroid hormones. There are a number of ginseng species, and each has its own set of ginsenosides.
