Diversity of culturable endophytic fungi vary through time in Manihot esculenta Crantz

Braz. j. biol; 84 (), 2024
Abstract Endophytic fungi are a ubiquituos group that colonize all plant species on earth. Studies comparing the location of endophytic fungi within the leaves and the sampling time in Manihot esculenta Crantz (cassava) are limited. In this study, mature leaves of M. esculenta from Panama were collected ...

Phytochemical Screening and chemical investigation of lipoidal matter of the leaves of Latania verschaffeltii Lem. Family Arecaceae cultivated in Egypt

Abstract This study presents the first preliminary phytochemical screening and investigation of the lipoidal matter of Latania verschaffeltii Lem. leaves, belonging to the Arecaceae family. Gas chromatography coupled with mass spectroscopy (GC/MS) was used to analyze and identify compounds of saponifiabl...
