Introduction: Recently, several endophytes have been shown to possess the potentials to synthesize novel bioactive compounds that have found use for drug discovery. We isolated endophytic fungi associated with Catharanthus roseus collected from the river banks of Amassoma in Southern Nigeria, and identified some of their bioactive secondary metabolites. Methods: The fungi were subjected to solid-state fermentation on rice medium and the metabolites were extracted using ethyl acetate. The fungal crude extracts were screened for antimicrobial activity and were also subjected to high-performance liquid chromatography-diode-array detection (HPLC-DAD) analysis for the identification of the bioactive compounds. Results: The fungal extracts showed both antibacterial and antifungal activities with minimum inhibitory concentrations ranging from 0.0625 to 1 mg/mL. The HPLC-DAD analysis of the extracts suggested the presence of citreoisocoumarin, citreoisocoumarinol, questinol, hydroxyemodin, acropyrone, methyl 2-(4-hydroxyphenyl) acetate, nigricinol, and cladosporin. Conclusion: The results of this study suggest that endophytic fungi associated with C. roseus could be a promising source of novel bioactive compounds with pharmaceutical and industrial importance.

Different Levels

An experiment was conducted to steady the effect of L-Tryptophan and salicylic acid on callus induced on leaf explants of Catharanthus roseus. Callus induction was achieved by culturing true leaves of the plant on Murashige and Skoog (MS) medium supplemented with 0.5 mg /L 2,4-D and 1mg / L Kin. The best medium to maintain callus was MS medium supplemented with 0.5 mg /L 2,4-D and 1.5 mg / L Kin. Different levels added to MS medium for each L-Tryptophan 0,200,300or400 mg /L and salicylic acid 0, 0.5,1or1.5mg /L. The medium supplemented with 30 g/ L sucrose was used as a control. Results showed the medium supplemented with 200 mgL of L-Tryptophan gave the highest quantity of Vincristine reached 48.66 µg/100 fresh weight of callus. MS medium content at the concentration 1 mg L of salicylic acid gave the highest level of Vinblastine recording 50.98 µg/100 fresh weight of callus. While MS medium supplemented with 0.5 mg /L of salicylic acid gave the highest level of Serpentine 24.76 µg/100 fresh weight of callus. The concentrations of active compound derived from plant leaves were much less than the concentrations produced by the callus grown in vitro. The concentration of Serpentine was 0.059 while Vinblastine was 0.183 and the concentration of Vincristine was 0.064.
