Anthers, Hydroxycinnamoyl polyamines A new hydroxycinnamoyl polyamine derivative, /V,/V',/V"-triferuloylspermidine (= (E)-N(4-aminobutyI)-3,3',3"-tris(4-hydroxy-3-methoxyphenyl)-N.N',N"-(butane-l,4-diyl)tris [prop-2enamide]) (1) was detected in the H20 /M e 0 H extract of pollen from Hippeastrum x hor torum. The compound was identified by on-line-coupled high-performance liquid chromato graphy and atmospheric-pressure chemical-ionization mass spectrometry (HPLC-UV(DAD)/ APCI-MS and MS/MS). The structure was proven by comparing the HPLC/MS data after UV-induced (£ ) ^ (Z) photoisomerization and catalytic hydrogenation of the natural com pound and the synthetic reference compound. This is the first report of a triferuloylspermidine in nature.

متن کاملAdjacency metric dimension of the 2-absorbing ideals graph
Let Γ=(V,E) be a graph and W_(a)={w_1,…,w_k } be a subset of the vertices of Γ and v be a vertex of it. The k-vector r_2 (v∣ W_a)=(a_Γ (v,w_1),… ,a_Γ (v,w_k)) is the adjacency representation of v with respect to W in which a_Γ (v,w_i )=min{2,d_Γ (v,w_i )} and d_Γ (v,w_i ) is the distance between v and w_i in Γ. W_a is called as an adjacency resolving set for Γ if distinct vertices of ...
متن کاملNew conditions on ground state solutions for Hamiltonian elliptic systems with gradient terms
This paper is concerned with the following elliptic system:$$ left{ begin{array}{ll} -triangle u + b(x)nabla u + V(x)u=g(x, v), -triangle v - b(x)nabla v + V(x)v=f(x, u), end{array} right. $$ for $x in {R}^{N}$, where $V $, $b$ and $W$ are 1-periodic in $x$, and $f(x,t)$, $g(x,t)$ are super-quadratic. In this paper, we give a new technique to show the boundedness of Cerami sequences and estab...
