Identification of antifungal compounds from slender amaranth

Abstract

HIGHLIGHTS  Antifungal activity of Amaranthus viridis leaves was evaluated against five phyto-pathogenic fungi.  Ethyl acetate leaf fraction reduced the fungal growth up to 48%.  GCMS analysis revealed 1,2-Benzenedicarboxylic acid, mono (2-ethylhexyl) ester) showing 58.5% peak area.

Masses, Radii and Regge Trajectories of $Σ_u^-$ State Hybrid Charmonium

“…The potential model [16] for conventional mesons is extended in ref. [7] for the study of Σ − u bottomonium mesons. This potential model for Σ − u charmonium states can be written as:…”

“…(2) The terms −4αs 3r , br, S c .S c , L.S, and S T are defined in [4], [7], [16]. Spin-orbit and colour tensor terms are equal to zero [16] for L = 0.…”

“…The parameters (A ′ , B ′ , P ′ , C ′ ) are found in ref. [7] by fitting A ′ exp(−B ′ r P ′ ) + C ′ with the lattice data [2] and fitted parameters are:…”

“…In ref. [7], linear plus coulombic potential model is extended for lowest excited hybrid state, Σ − u by fitting the lattice data [1] with the suggested analytical expression (ansatz). The validity of suggested ansatz is tested by calculating the spectrum of Σ − u state bottomonium mesons.…”

“…The validity of suggested ansatz is tested by calculating the spectrum of Σ − u state bottomonium mesons. In this paper, this extended potential model [7] is used to calculate the spectrum and radii of the of Σ − u charmonium hybrid mesons. For this purpose, Born-Oppenheimer formalism and adiabatic approximation is used.…”
