UFLC–MS/MS analysis of four tanshinone components in Salvia miltiorrhizae after ultrasound-assisted extraction

Multiple target cell extraction and LC-MS analysis for predicting bioactive components in Radix Salviae miltiorrhizae.

A method for predicting bioactive candidates in herbal medicines (HMs) was developed using four types of target cell extraction followed by high performance liquid chromatography coupled with diode array detection-mass spectrometry (HPLC-DAD-MS) analysis. Through the proposed method, some potential bioactive components in Radix Salviae miltiorrhizae, a widely used HM for the treatment of cardio...

Investigation on ultrasound-assisted extraction of salvianolic acid B from Salvia miltiorrhiza root.

It is reported that salvianolic acid B, a bioactive phenolic compound contained in the root of Salvia miltiorrhiza, exhibits a much stronger activity in free radical scavenging and antioxidance than those of vitamin E. When a conventional refluxing method is adopted to extract salvianolic acid B from the root, in which the materials are subjected to higher temperature and longer time, the yield...

Optimization of phenol and flavonoid extraction compound of Adiantum capillus-veneris L. using ultrasound assisted extraction

Background: Antioxidants are molecules which able to control free radicals and prevent the oxidants of other molecules considering undesirable effects of synthetic anti oxidant. In recent years using of natural anti oxidant gets the great importance. The secondary metabolisms of plants are rich sources of phenol and flavonoids considered as the most important natural antioxidant.  Objective: In...

Effect of Ethanol Concentration in Ultrasound Assisted Extraction of Glycyrrhizic Acid from Licorice Root

Deep Eutectic Solvent-Based Microwave-Assisted Method for Extraction of Hydrophilic and Hydrophobic Components from Radix Salviae miltiorrhizae.

Deep eutectic solvents (DESs) have attracted significant attention as a promising green media. In this work, twenty-five kinds of benign choline chloride-based DESs with microwave-assisted methods were applied to quickly extract active components from Radix Salviae miltiorrhizae. The extraction factors, including temperature, time, power of microwave, and solid/liquid ratio, were investigated s...
