Ethnobotanical study, antifungal activity, phytochemical screening and total phenolic content of Algerian Aristolochia longa

摘要

Aim: Aristolochia longa (from the family Aristolochiaceae) is widely used in Algerian traditional medicine. Here we document ethnomedicinal uses by local population of Mascara province (west Algeria) and we evaluate the antifungal activity, the phytochemical composition and total phenolic content of aqueous extract (decoction) of the roots of A. longa from Algeria. Material and Methods: The ethnobotanical investigation was carried out in Mascara Province (West Algeria). Antifungal activity was assessed against Saccharomyces cerevisiae. Total phenolic content was measured using the Folin-Ciocalteu’s reagent. Results: Our results showed that A. longa is widely used to treat several ailments such as cancer (38%), skin infections (14%) and diabetes (11%). Crushed roots are commonly used (89%) mixed with honey, milk, water or other medicinal plants. A. longa aqueous extract induced growth inhibition of S. cerevisiae cells in a dose- and time- dependent manner. An effective suppression of S. cerevisiae (97.06% inhibition of proliferation) was obtained at the 500μg/ml after 72h. Results of the phytochemical screening revealed that A. longa aqueous extract contained various bioactive compounds, including polyphenols and flavonoids. Total phenolic content in A. longa aqueous extract was found to be 6.07±0.12 mg (GAE)/g. Conclusion: A longa may be considered as a promising source of new drugs for treating cancer and as a good antifungal agent.
