This work is a Taxonomic study based on genus Lawsonia L. in Tehama area, Albaha region—Saudi Arabia. It includes scientific description of the family Lythraceae and scientific classification of the species Lawsonia inermis L. The study aims to: 1) Identify Lawsonia inermis L. species in Tihama—Albaha region. 2) Determine the distribution and habits of the species Lawsonia inermis L. 3) Provide medicinal properties and local uses of Lawsonia inermis L. Botanical names and synonyms were updated. Vernacular names have been presented. Botanical description is determined depending on the vegetative of the plant. Flowers and fruits were characterized. The method was recorded due to Dr. Jacob Thomas, Herbarium Dept., College of Science, King Saud University [1]. Information about habitats and distribution was provided. The plant species has been illustrated by photos in its habitat. Chemical components, medicinal properties and local uses were included. The study revealed that Lawsonia inermis L. is widely spread throughout the study area and it has great medicinal importance, so it requires more comprehensive studies for identification. Therefore, more Biochemical studies on the effective chemical compounds are required for the medicinal importance of the plant. The results revealed that there were many medicinal properties and local uses of Lawsonia inermis L.

Green inhibitors are promising alternatives to toxic corrosion inhibitors as they are environmentally safe substances, ecologically acceptable and renewable. In this research, the effect of green henna as an inhibitor existing in the coating of TMSM-PMMA and its electrochemical study were analyzed. The coating was produced by “sol-gel” method in order to protect the corrosion of low-carbon steel. TMSM hybrid cell was synthesized by hydrolysis and condensation, Metaacryloxypropyltrimethoxysilane and Tetraetylorthosilicate with 1:1 molar ratio and PMMA hybrid cell was produced by Methylmetaacrylate polymerization. Finally two cells were mixed in 1:1 weight ratio. The carbon steel substrates were prepared by dip coating method. SEM technique was applied for the microstructure evaluation of thin layers including different concentrations of henna extract. Adhesion of coating was analyzed by “Pull off” test. Additionally, the experimental results obtained in different concentrations of henna extract using electrochemical methods such as tafel polarization, electrochemical impedance spectroscopy indicating that coating with the concentration of 3% inhibitor had a high level of inhibition efficiency in 0.1 M HCL. The results of polarization tests signified that henna extract acts as a mixed inhibitor.

A new simple and sensitive kinetic spectrophotometric method has been proposed for the determination of cefadroxil in pure form and pharmaceutical formulations. The proposed method is based on the formation of yellow coloured product (λmax = 410 nm) that resulted after addition of the reagent, which is composed of a mixture of henna extract, sodium hydroxide and potassium permanganate, to cefadroxil aqueous solution. The experimental conditions have been optimized. Beer’s law is obeyed over the concentrations of 100 - 35 μg/ml, with a linear regression correlation coefficient of 0.996. The proposed method has been successfully applied for the determination of cefadroxil in pharmaceutical dosage forms.
