  • Abstract

    Background: Asparagus sprengeri  Regel. is an ornamental small shrub native to coastal southeastern South Africa. The main objective of this study was the phytochemical and biological evaluation of ethanolic extract of non-flowering aerial parts of Asparagus sprengeri Regel., growing in Egypt. Methods: The investigation included analysis of the lipoidal compounds in the unsaponifiable and fatty acids fractions by GC/MS. Quantitative estimation of polyphenols, flavonoids and saponins by colourimetric methods. HPLC analysis of polyphenolic compounds was undergone, in addition to LC/MS of the saponins. Isolation of flavonoids was undergone using chromatographic methods and the identification was accomplished on the basis of their spectral data. Results: The unsaponifiable fraction was composed mainly of hydrocarbons (52.99%) and alcohols (31.54%). Moreover, the fatty acids fraction was composed of saturated (52.12%) and unsaturated (21.61%) ones. Determination of total polyphenols (9.83%) and flavonoids (1.87%) was undergone. HPLC analysis of polyphenols revealed that flavonoids were detected in higher amounts than phenolic acids. Extraction, isolation and identification of three flavonoids (kaempferol, quercetin and genistin) was achieved. Saponins (2.44%) were determined, while LC/MS of the n-butanol fraction indicated the presence of sprengerinin A,B,C&D. The ethanolic (70%) extract exhibited moderate antioxidant (IC50 = 56 µg ml-1) and potent cytotoxic activities. The most potent activity was that on colon cell line (IC50 = 3.73 µg ml-1), followed by the breast cell line (IC50 = 10.20 µg ml-1). Conclusion:  Thus, non-flowering aerial parts of Asparagus sprengeri Regel. could be considered as a potential source for different bioactive metabolites.
