Untargeted metabolite profiling and phytochemical analysis of Micromeria fruticosa L. (Lamiaceae) leaves.

Micromeria fruticosa is an important crop, is widely used in the Mediterranean basin as food and in folk medicine, owing to its health-promoting properties, partially due to the secondary metabolite composition. However, complete information on the phyto-metabolites in M. fruticosa is still lacking.

Synthesis and characterization of hybrid materials consisting of n-octadecyltriethoxysilane by using n-hexadecylamine as surfactant and Q(0) and T(0) cross-linkers.

Novel hybrid xerogel materials were synthesized by a sol-gel procedure. n-octadecyltriethoxysilane was co-condensed with and without different cross-linkers using Q(0) and T(0) mono-functionalized organosilanes in the presence of n-hexadecylamine with different hydroxyl silica functional groups at the surface. These polymer networks have shown new properties, for example, a high degree of cross-linking and hydrolysis.

N'-(Di-2-pyridylmethyl-ene)benzo-hydrazide.

In the title Schiff base, C(18)H(14)N(4)O, the amido -NH- unit is connected to one of the two pyridyl N atoms at an N(-H)⋯N distance of 2.624 (2) Å. The mol-ecular packing features an inter-molecular C-H⋯N R(2) (2)(6) hydrogen-bonding ring motif.
