Regeneration of germlings and seedlings development from cauline leaves of Sargassum thunbergii
A method of producing artificial Sargassum thunbergii seedlings is urgently desired to meet the increasing demand of raw materials used for aquaculture and for the sake of environmental protection. This is the first report of attempt to study the vegetative propagation of this species using cauline leaves under laboratory conditions. On average, 45.75% of the excised leaves survived and one leaf could produce several...

Synthesis, characterization and biological activity of some novel azetidinones
A series of seven novel azetedinones 4a-g have been synthesized by cyclocondensation of various Schiff bases of phenothiazine with chloroacetyl chloride in presence of triethylamine. Various Schiff bases of phenothiazine were synthesized by condensation of 2-hydrazinyl-1-(10H-phenothiazin-10-yl)ethanone 2 with various aryl aldehydes. Compound 2 was synthesized by reacting 2-chloro-1-(10H-phenothiazin-10-yl) ethanone 1...
