Abstract

The goal of this survey is to determine the amount of flavonoids in the leaves and stems of Secamone afzelii (Asclepiadaceae), a plant possessing some antioxidants qualities. The phytochemical screening revealed that the flavonoids are more abundant in the leaves than in the stems. The amount of anthocyane is 336 mg/100 g in the leaves, whereas it is only of 180 mg/100 g in the stems. We also discovered that the stems did not possess aglyconic flavonoids while the amount is 86 mg/100 g in the leaves. This plant’s flavonoid have several structural shapes. All these flavonoids could act in synergy in order to increase the antioxidant property of S. afzelii.

Key words: Secamone afzelii, flavonoids, anthocyanine, aglycones, antioxidant.
