Bio-Taxonomic Study Based on Selected Aromatic Plants Species Related to Different Plant Families as Raw Material

Abstract

This work is an attempt to make a taxonomic study on some aromatic plants in Tehama area, Al-Baha region Saudi Arabia. It includes a brief description on climate, topography and geology of the study area. The total number of species identified were (4) species depending on their differences in vegetative, floral and fruit characteristics. Scientific classification of each species is provided. Botanical description with notes on habitats and distribution were determined for all of the four species. Medicinal properties and local uses for some species were included. All identified species have been illustrated by photos in their habitats. Botanical names, synonyms were updated and vernacular names (Local names) have been presented. The study revealed that all species have a great ecological, economic and medicinal importance and require more comprehensive studies to conserve them. The study aims to: 1- Determine the distribution and habits of the species of Aromatic plants. 2- Provide medicinal properties and local uses of Aromatic plants and species. The method was recorded due to Dr. Jacob Thomas, Herbarium Dept., College of Science, King Saud University. The four selected aromatic plant species resulted essential oils, antioxidant activities and volatile oils. Technical methods such as Gas Chromatography (GC) were used to identify the components. The authors recommend accurate techniques such as DNA fingerprinting to identify these species as they are considered to be a native heritage for their country
