Abstract

Two pigment producing fungi, Talaromyces atroroseus and Penicillium choerospondiatis, were isolated and identified from infected fruits of Phyllanthus emblica L. based on amplification and sequencing of internal transcribed spacer region and beta-tubulin gene. This is the first occurrence report of these two fungi from fruits of P. emblica. Culture extract containing metabolites of T. atroroseus and P. choerospondiatis contained phenolics of 26.35 mg and 30.89 mg GAE/g dry extract respectively; whereas no significant amount of flavonoids and tannins were detected. P. choerospondiatis metabolites extract showed higher DPPH and ABTS activity with IC50 values of 21.94 mg/ml and 27.03 mg/ml respectively than T. atroroseus. LC-HRMS analysis of metabolites extract of T. atroroseus revealed presence of trimethyl-isopropyl-butanamide, perlolyrine, N-hexadecanoylpyrrolidine etc. whereas P. choerospondiatis displayed presence of tangeraxanthin, ugaxanthone, daphniphylline, etc. Therefore, fungal metabolites are rich natural sources of diversified compounds that can be utilized in dyeing industries, cosmetics and novel drug development.
