The present paper is to study and develop a method for online monitoring of the column separation and purification process of active components that are madecassoside and asiaticoside of Centella asiatica L. Urban using near-infrared (NIR) spectroscopy technology. After collecting 50%-ethanol eluant, we detected their NIR spectra and developed the high(More)
A method was developed for online monitoring of the constituents of ginsenoside of Folium Ginseng in the column separation and purification process using near-infrared (NIR) spectroscopy technology. Determination method of ginsenoside Rg1, Re and Rb1 was developed by high performance liquid chromatography (HPLC). After collecting 40%-ethanol eluant, their(More)
In the present paper, the use of near infrared spectroscopy (NIR) as a rapid and cost-effective classification and quantification techniques for the authentication of virgin olive oil were preliminarily investigated. NIR spectra in the range of 12 000 - 3 700 cm(-1) were recorded for pure virgin olive oil and virgin olive oil samples adulterated with(More)
Serum albumin is the most abundant protein in plasma. It can bind with many intrinsic and extrinsic materials. The study of the interaction between serum albumin and drugs is a very important task in life science and chemistry. Quinolone drug is a kind of antibacterial drugs which have been used widely in clinical medicine, but its pharmacology and(More)
