Syagrus flexuosa (Mart.) Becc. (Arecaceae) seedling recruitment at the edge and interior of Cerrado remnants

Braz. j. biol; 84 (), 2024
The edge effect has impacts on seed and seedling survival due to modifications in biotic and abiotic factors. Often, large-seeded tree species lost seed vectors in the forest edge due to the rarity or absence of large frugivores at this habitat type. In this study, I compared the seedling abundance and d...

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...

Development and characterization of photoprotective nanoemulsions containing Babassu (Orbignya phalerata Mart. ) lipophilic extract

Abstract Oil-in-water photoprotective nanoemulsions (NEs) were developed using Babassu (BBS) lipophilic extract, nonionic surfactants, and low concentrations of organic sunscreens by ultrasonic processing. BBS extract was chosen due to its suitable physicochemical properties (acidity index, peroxide inde...

Diversity and genetic structure of natural populations of the palm tree Euterpe precatoria (Arecaceae)
