ABSTRACT

Objective To study the protective effect of phenethyl alcohol glycosides extracted from Herba Cistan-chis on human sperm DNA with oxidative damage by Raman spectroscopy. Methods The human sperm model of oxidative damage was induced with Fenton’s reagent in vitro. After co-cultured with the phenethyl alcohol gly-cosides extracted from Herba Cistanchis ( in the dosage of 0.1, 0.01 and 0.001 μg/mL) , the changes of the sperm nuclear DNA were observed by using confocal micro-Raman spectroscopy. Results The intensity and peaks of the Raman spectra of the human sperm nuclei treated by Fenton’s reagent were changed significantly, and then the changes of intensity and peaks were inhibited after treatment with phenethyl alcohol glycosides of Herba Cistanchis, the inhibition being dose-dependent. Conclusion The phenylethyl alcohol glycosides ex-tracted from Herba Cistanchis have protective effect on human sperm DNA with oxidative damage.

ABSTRACT

OBJECTIVE:To extract phenolic acid from Salvia militiorrhiza by multi-stage countercurrent extraction technology. METHODS: The multi-stage countercurrent extraction technology and traditional single pot decocting extraction technology were applied to extract phenolic acid from S. militiorrhiza. The content of salianic-acid B was determined and energy consumption of these extraction technologies were calculated and compared. RESULTS: As compared with traditional single pot decocting extraction technology, multi-stage countercurrent extraction technology effectively decreased the degradation of active component, energy consumption and production cycle. CONCLUSION: Multi-stage countercurrent extraction technology is suitable for the production of S. militiorrhiza.
