A weed population survey was carried out to assess the variability in species composition and abundance main coffee production systems regions of Ethiopia. total 168 fields were assessed using a quadrat count systematic sampling technique. Weed evaluated frequency, dominance at each site. We found 98 taxa belonging 35 families, which Asteraceae Poaceae most abundant. The frequent Oplismenus hir...

Weeds are unwanted wild plants because they can interfere with the main crop cultivation. This study aims to identify and analyze diversity of weed vegetation that grows around mango trees. uses quadratic method diagonal observation points direct exploration techniques. Observation parameters include type its population. Then results observations were analyzed using formula Important Value Inde...

A new compound, chandonanol (1), along with four known compounds, chandonanthone (2), iso-chandonanthone (3), anastreptene (4), and (6R,7S)-sesquiphellandrene (5), was isolated from the MeOH extract of Bornean liverwort Chandonanthus hirtellus. The structure of the new metabolite was established by analyses of the spectroscopic data (1D NMR, 2D NMR, HRESIMS, and IR). These compounds were tested...
