Fungal endophytes in Peperomia obtusifolia and their potential as inhibitors of chickpea fungal pathogens.

Chickpea (Cicer arietinum L., Fabaceae) is the second most important legume after common bean (Phaseolus vulgaris L., Fabaceae) and third in production among the legumes grains worldwide.

Antibacterial activity of prenylated benzopyrans from (Piperaceae).

is a herbaceous perennial plant native to the Americas reported as a traditional medicine to treat snake bites and as a skin cleanser. The bioassay-guided fractionation of crude extracts from aerial parts of against a panel of clinically important fungi and bacteria, showed that hexane and dichloromethane extracts demonstrated selective bacterial inhibition, allowing the isolation of the known compounds peperobtusin A (), and 3,4-dihydro-5-hydroxy-2,7-dimethyl-8-(3"-methyl-2"-butenyl)-2-(4'-methyl-1',3'-pentadienyl)-2H-1-benzopyran-6-carboxylic acid () from dichloromethane extract. Compound was active against Gram-positive bacteria including community acquired methicillin-resistant (CA-MRSA) isolates and an vancomycin-resistant strain, with minimal inhibitory concentration (MIC) values of 4 μg/mL (10.
