Tableting technology from the individual and new galenic alkaloid consisting preparations of the Phellodendron lavallei bark

The aim of the research was to work out the technology and tablet composition from new galenic preparations consisting of alkaloids of the bark of Phellodendron lavallei and hydrochloride of berberin on the base of complex research. The bark of the Phellodendron lavallei introduced in Georgia contains alkaloids, from which 2% is berberine used for curing chronicle hepatitis, hepatic cholecystitis and bilestone disease. The structural-mechanical and technological character of tablets and their masses were defined by the known methodic. Friability was studied by defining the fluctuation and bending corner. Volume density was established by using vibration cylinder. Volume density of powders was studied by pyknometers. Porosity was calculated by the bearing of volume density of the masses. The size of pressing was established by defining the firmness of tablets. The granule composition was defined by analysis. On the basis of studying technological and physical-chemical character features of the substances of new galenic preparations and individual substances consisting of alkaloids got from the bark of Phellodendron lavallei, it is scientifically proved and practically offered optimal technological parameters of tablets forming process and recipes.

Anatomical and morphological description of Phellodendron lavallei Dode stem bark

Phellodendron lavallei Dode (Rutaceae) is native to Japan. It was introduced in Georgia (Adjara) in 80th of XX century. In medicine the genus of Phellodendron Rupr. has been used to treat gastric ulcers, bacterial and fungal infections, inflammations, hyperglycemia. The bark is rich of alkaloids of protoberberine type and may be used as a source of them. There are very limited data about anatomical and morphological structure of this genus. Especially least investigated is grown in Georgia. The aim of our study was to investigate anatomical and morphological structure of stem bark Phellodendron Lavallei Dode introduced in Georgia and evaluate its micro structural characteristics. The bark is collected in Kobuleti medical plants experimental station in July and November of 2009 year. There were examined longitudinal and cross sections of herbal material. The bark was studied using a light (Carl Zeiss, Jeneval) and (MBC-2) stereoscopic microscopes. During the structural study of P. lavallei it was manifested the variety of diagnostic signs: the cork is covered by small warts. It's characteristic to corks to peel off the dead tissues. Its cellular structure is rich in chloroplasts. Both in primary, and in secondary structure of a stem bark it is developed many of the sclerenchymal (fibres, mechanical cages) sites. The cork's cambium (phellogen) is characterized by small regions of cork's parenchyma, in which the idioblasts are arranged. In the bark there is massive size monarchic type radial rays, intensively stretched from the central cylinder till the primary cork's parenchymal tissue, they transport and preserve the substances received as a result of physiological processes. A variety of the tissues of Phellodendron lavallei stem bark indicates on high quality of medical raw materials and activity of the physiological processes in a plant.
