It can relieve the fatigue, postpone caducity, resist the side effect of anoxia and microwaveradiation, it also have the ability of promoting the mental energy and body function etc.


1. Effect of salidroside on cultured myocardial cells anoxia/reoxygenation injuries

The effects of salidroside (p-hydroxyphenethyl glucoside, Sal, first isolated and synthesized in China) on reoxygenation damages were studied on cultured myocytes from neonatal rat hearts. At least 80% of cells in the form of monolayer contracted spontaneously on cultured 72 h, then the cells were used in the contractility experiment. After anoxia 3 h and reoxygenation for 1 h the beating of myocardial cells was slowed down and the lactate dehydrogenase (LDH) liberated by myocardial cells was increased. Electron microscopy of myocardial cells revealed localized defects of cell membrane, dilatation of endoplasmic reticulum, and swelling of mitochondria. One h before anoxia, addition of Sal 10 and 30 increased the beat rate of myocardial cells, depressed the release LDH of from myocytes, and the myocardial ultrastructure was normal during anoxia and reoxygenation. Hence Sal may provide some protective effects on the anoxia/reoxygenation damages upon myocardium.

2. Separation of salidroside from Rhodiola crenulata by high-speed counter-current chromatography.

High-speed counter-current chromatography (HSCCC) was used to purify salidroside from an extract of Rhodiola crenulata with two steps using a two-phase solvent system composed of ethyl acetate-n-butanol-water (1:4:5, v/v) in the first run and chloroform-methanol-isopropanol-water (5:6:1:4) in the second run. The method yielded 21.9 mg of salidroside from 1.216 g of the crude sample at 98% purity determined by HPLC analyses. Identification was performed by 1H NMR, 13C NMR, and MS.

3. High yield production of salidroside in the suspension culture of Rhodiola sachalinensis

Salidroside has been identified as the most potent ingredient of the Chinese medicine herb, Rhodiola sachalinensis. Since the natural supply of this herb is rapidly decreasing, we established a compact callus aggregate (CCA) strain and culturing system for high yield salidroside production. Several callus strains induced from the explants originated from root, stem, leaf and cotyledon of R. sachalinensis were established and screened for rapid growth rate, high salidroside content and easy propagation in suspension culture condition. The CCA strain was established from a callus strain initiated from the cotyledon. The kinetics of dry weight accumulation and cellular salidroside content in various culture conditions for the strain was determined. For high salidroside production, the optimal inoculum amount was 10% and the optimal concentration for 6-benzylaminopurine and indole-3-butyric acid added in the liquid medium was 5 and 2.5 mg l-1, respectively. The acidic culture medium and a faster shaking speed favored the salidroside accumulation. The addition of 2,4-D, in the liquid MS medium and the utilization of L-tyrosol for chemical feeding enhanced salidroside production. Using a proper combination of culture condition and treatment, salidroside accumulation could reach 57.72 mg g-1 dry weight, that was 5-10-fold higher than that detected in field-grown plants. The corresponding salidroside yield was 555.13 mg l-1, a level suitable for cost effective commercial production to compensate the natural resource shortage of R. sachalinensis.
