Objective: To Analyse the major phytochemical components in selected varieties of P. betle leaves using GC-MS.Methods: P. betle leaves were shade dried and pulverized to powder in a mechanical grinder. The powder was successively extracted with ethanol (40-60 °C). The extracts were concentrated under reduced pressure in a rotary evaporator. The ethanolic extracts of the plant leaves were used for GC-MS analysis.
Results:In the present study ten chemicals were identified and compared from the P. betle varieties, the major component being Eugenol, which is responsible for the flavour and aroma of the leaves.
Conclusion:Variety Karpoori possesses the highest content of Eugenol and could be used as a promising variety in the pharmaceutical industry. The components of essential oil can also serve as a determinant to distinguish different varieties of betle vine cultivars.
The anatomical, chemical, and physico-mechanical properties of the fibres of C. pangorei were investigated in this study. The results indicate that the rind region that is split and used in mat making contains compactly arranged fibrovascular bundles and a discontinuous patch of fibrous sheath. The frequency and the R/T ratio of the bundles were high in the rind region and were indicative of fibre strength. Lignin and cellulose, the major cell wall substances, were localized with heterochromatic, fluorescent, and natural dyes. The holocellulose content was high (82.2 %), and the lignin content was comparatively low (13.28 %) as analyzed by the method of Doree. Very thick walled, thick walled, very thin walled, and thin walled fibres were characterized when fibres were macerated, and their derived values indicated a high Slenderness and Runkell ratio that is indicative of tear resistance. The tenacity and percentage elongation of the split culm strands was also high, and this implies high strength of the fibre strands. The fibre of this mat sedge thus has favorable characteristics to be potentially utilized in the mat and silkmat industry. Furthermore the plant’s annual harvesting period, biomass, and appropriate fibre characteristics makes this sedge very attractive as an alternative fibre source in the miscellaneous plant fibre industry.
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.
