Only registered users can translate articles

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

Influence of naturaldecay of fibrousroots on growth and content of active compositions of Salvia miltiorrhiza f. alba.

Only registered users can translate articles

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),

[Extraction of three tanshinones from the root of Salvia miltiorrhiza Bunge by supercritical carbon dioxide fluid and their analysis with high performance liquid chromatography].

Only registered users can translate articles

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

Matrix Solid-Phase Dispersion Coupled with High-Performance Liquid Chromatography Diode Array Detection for Simultaneous Determination of Four Lipophilic Constituents from Salvia miltiorrhiza Bunge.

Only registered users can translate articles

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
