tanshinone ii/salvia miltiorrhiza

OBJECTIVE To explore a method on-line determining the contents of tanshinone II A in returning extraction process of Salvia miltiorrhiza by AOTF-Near infrared spectroscopy. METHODS Firstly, the sample was collected in the extraction process of Salvia miltiorrhiza. Then HPLC was used as a reference

BACKGROUND Salvia miltiorrhiza Bunge is a traditional Asian medicine used to treat cerebral and cardiac ischemia. However, the effects of the active compounds of S. miltiorrhiza on liver damage are unclear. OBJECTIVE In this study, we tested the effects on acute liver injury of crude S. miltiorrhiza

To study the effect of plant-derived smoke water on the accumulation of biomass and active substance of Salvia miltiorrhiza f. alba, seedlings of S. miltiorrhiza were treated with different concentrations of smoke water (1:500, 1: 1 000, 1: 2 000). The fresh weight and dry weight of underground

The change of yield and contents. of active compositions were studied while the fibrous roots were decayed naturally. HPLC method was used to detect the contents of active composition. The results show that fibrousroots could decrease the production of plant by 38.60% (20 g) and 30.99% (40 g),

The extraction of three tanshinones from the root of Salvia miltiorrhiza Bunge by supercritical carbon dioxide (SC-CO2) fluid with ethanol as co-solvent was investigated using four-factor and three-level orthogonal design method and the systematic method. The optimized conditions were established as

A simple, rapid and efficient method based on matrix solid-phase dispersion coupled with high-performance liquid chromatography was developed for determination of lipophilic constituents, including dihydrotanshinone, tanshinone I, cryptotanshinone and tanshinone II A in Salvia miltiorrhiza Bunge

On-line continuous sampling, ionic liquid-based dynamic microwave-assisted extraction high performance liquid chromatography has been developed and applied to the extraction of lipophilic constituents from root of Salvia miltiorrhiza Bunge. Several operating parameters were optimized by

OBJECTIVE The powder characteristic, water extraction amount and active ingredients cryptotanshinone (CTS), tanshinone II A (TS) and protocaechuic aldehyde (PA) were comparatively studies between crude powder and micronized powder to study the application of micronization technology to Salvia

Fourteen constituents were isolated from the roots of Salvia miltiorrhiza f. alba. Two of them were new compounds and were named 1,2,15,16-tetrahydrotanshiquinone (I) and tanshinaldehyde (II). The others were identified as Ro-090680 (III), dihydroisotanshone I (IV), danshexinkun B (V), miltirone

OBJECTIVE To establish a new method and validate its feasibilities for quality evaluation of Salvia miltiorrhiza. METHODS Four main effective components, dihydrotanshinone I, cryptotanshinone, tanshinone I and tanshinone II(A), were selected as analytes to evaluate the quality of S. miltiorrhiza.

OBJECTIVE To study the relationship between plant growth and accumulation of active ingredients in Salvia miltiorrhiza. METHODS Transplants of S. miltiorrhiza were sampled at 20 day intervals. At each stage, the growth of seedling and root system was recorded and the contents of tanshinone II (A)

In an attempt to apply high-speed counter-current chromatography HSCCC for TCM fingerprints, the separation and purification of the Chinese medicinal plant Salvia miltiorrhiza Bunge of different localities was realized using the technique. The equipments used include a HSCCC (TBE-300) of Shenzhen

OBJECTIVE To study the culture of adventitious root of Salvia miltiorrhiza in vitro systemically. METHODS Effects of sucrose concentrations, medium pH, inoculum size and plant growth regulators on adventitious root growth and secondary metabolites production in S. miltiorrhiza were

OBJECTIVE To investigate the in situ extraction effect of macroporous resins on tanshinones in Salvia miltiorrhiza hairy root. METHODS Macroporous resins were added to S. miltiorrhiza hairy root culture and the contents of three major tanshinones (crypotanshinone, tanshinone I and tanshinone II(A))

Biological characteristic of Salvia miltiorrhiza f. alba in field was studied. HPLC method was used to determine the lipophilic constituents (dihydrotanshinone, cryptotanshinone, tanshinone, tanshinone II (A) and miltione) and hydrophilic constituents (salvianolic acid, rosemarinic acid). The
