Flueggea leucopyrus belongs to family Phyllanthaceae, commonly known as 'Katupila'or 'Heen katupila' and has become increasingly popular as an ingredient in several traditional therapeutic systems in Sri Lanka as well as in other Asian countries. A questionnaire survey was carried out using a hundred population sample to determine the awareness of the distribution and therapeutic uses of F. leucopyrus in Sri Lanka as a preliminary survey. The aims of the present study were to interpret the phenetic variation and determine the variation of phenolic composition in leaf extracts of F. leucopyrus in different climatic zones in Sri Lanka and to develop a suitable propagation system for F. leucopyrus. Eleven floral and vegetative characters of F. leucopyrus were observed and cluster analysis was carried out to infer phenetic relationships among populations collected from localities, Colombo, Kurunegala, Puttalam and Hambanthota, .representing different climatic zones. Medicinal value of most of plants lies in phytochemicals such as phenolics, flavonoids and anthocyanidins. Thus, leaf samples were extracted into ether, and ether extracts were used to isolate phenolic compounds using 2-Dimensional paper chromatography in solvent systems, butanol: acetic acid: water; 6:7:3 and sodium formate: formic acid: water; 10:1:200. Colors of the spots were observed under UV (366nm), and Rf values were calculated. Intra specific variations were observed in the distribution of phenolics in leaves and phenetic characters of F. leucopyrus with respect to their habitats
Osbeckia octandra (Melastomataceae) is a rare endemic perennial plant with a high medicinal value which can also be used as an ornamental species as it bear beautiful violet colour flowers. Though the availability of these plants have restricted to certain areas of the country and has a limited distribution it should be propagated using successful mass propagation techniques.
Genus Tephrosia (Fabaceae) commonly known as 'Pila' in Sri Lanka. Some Tephrosia spp. are used in many traditional therapeutic preparations in Sri Lanka and also in other countries. Increased use of Tephrosia in traditional therapeutic systems has developed a great demand for these species. Thus production of planting materials for commercial cultivation has become a timely requirement. Therefore, this research was conducted to determine suitable propagation systems for four selected Tephrosia spp.; T. purpurea, T. villosa, T. noctiflora and T. pumila. Even though seeds of Tephrosia spp.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
