Résumé
Objective To investigate the chemical constituents of the ethanol extract of Daphne altaica Pall (DA-Et), to determine total phenolic content in DA-Et and to study the effect of DA-Et on cell apoptosis in Eca-109 cells. Meth?ods Different chemical assays were performed to detect chemical constituents of DA-Et. The content of total phenolics ,ex?pressed as gallic acid equivalents,was measured by Folin-Ciocalteu assay; Cell apoptosis induced by DA-Et was detected by AnnexinV-FITC/PI flow cytometry. Results Flavonoids,coumarins,sugars,alkaloids and phenolics in DA-Et. The contents of total phenolics in DA-Et was quantified as 159.78 mg/g. Average recovery rate of this method ranged from 99.4% to 108.3% and the precision relative standard deviation was 2.04%. Apoptosis rate of Esophageal cancer cell line Eca-109 induced by DA-Et was detected as 29.633%±1.779%(n=3). Conclusion Our study provide guidance for the im?provement of DA-Et quality, its appropriate application and further research of its activity.
Résumé
Tasmayi (mumie, shilajit) is a pale brown to black substance which leaks from the layers of rocks in many mountain ranges during the warm summer months. In traditional Kazakh medicine, it is used for the treatment of bone fracture and many inflammatory ailments. It is also used as a remedy in the traditional medical systems of many countries such as India, Russia and Kazakhstan. According to the literatures, Tasmayi possesses anti-inflammatory, antiulcerogenic, antibacterial, free radical scavenging, antioxidative, memory enhancing, antidiabetic, antistress, antiallergic, immunomodulative, anti AIDS, anabolic and regeneration stimulating activities. The major physiological action of Tasmayi could be belonging to the presence of dibenzo-alpha-pyrones along with humic and fulvic acids.
