ABSTRACT
OBJECTIVE:
To study the chemical constituents from the rhizome of Drynaria fortunei and the protective effects of them on PC12 cells induced by Aβ25-35.METHODS:
The compounds were isolated and purified by silica gel, Sephadex LH-20, ODS column chromatography, and their structures were identified on basis of spectroscopicMETHODS:
, such as MS and NMR. PC12 cells were treated with Aβ25-35 to establish the Alzheimer' s disease models. The compounds of different concentrations were added into culture medium to detect the protection. MTT assay was used to detect cell vitality and to observe the protective effects of compounds on PC12 cells induced by Aβ25-35.RESULTS:
Nine compounds were isolated and identified as naringin(1), neoeriocitrin(2), 5,7-dihydroxychromone-7-neohesperidoside(3), (E)-4-O-β-D-glucopyranosyl caffeic acid(4), kaempferol(5), luteolin(6), protocatechoic acid(7), psoralen(8), and β-sitosterol(9). The cell experiments were performed on the compounds 1-8 and theRESULTS:
showed they can promote the proliferation of PC12 cells. The cell vitality increase with concentration rising, and the difference is statistically significant (P<0.05).CONCLUSION:
Compounds 1-8 play an important role in protecting Aβ25-35-induced injury in PC12 cells and they are the main active components of Drynaria fortunei in the protection of central nervous function.
