GC-MS Analysis of Chemical Compounds from Some Yemeni Medicinal Plants
The traditional medicine still plays an important role in the primary health care in Yemen. The current study represents the investigation of OcimumForskoleiplant , which were collected from (Sana'a -Yemen). Basil (OcimumForskolei ) is an important medicinal herb belonging to the basil family, Lamiaceae. Basil, one of the most popular herbs grown in the world, is native to Asia (Yemen, India, Pakistan, Iran, Thailand, and other countries) and can be observed growing wild in tropical and sub-tropical regions. Essential oils are volatile, natural, complex mixtures of compounds characterized by a strong odour and are formed by aromatic plants as secondary metabolites. Essential oilextracted from roots ofOcimumForskolei wasinvestigated using gas chromatography/mass spectrometry techniques (GC/MS). Fifty-four compounds were identified, comprising about 100 % of the total oil. Bicyclo [3.1.1] hept-2-ene, 2 (23.364 %),Bicyclo[3.1.1] hept-2-ene, 2 (9.00 %), trans-Caryophyllene (3.238 %), Naphthalene, 1,2,3,4,4a,5,6, (19.32 %), alpha.-selinene (3.98 %), alpha.-Humulene (2.95%), Naphthalene 1,2,3,4,4a,5,6,(5. 927 %), Naphthalene, 1,2,3,4,4a,5,6 (3.01%), Phytol (4.700 %), Azulene, 1,2,3,5,6,7,8,8a-oc (6.21 %), Copaene (1.48%), Estragole (1.733%), Cedrene (1.00%) and other compounds were found to be the major fraction of the oil. The different types of compounds, which could be responsible for antioxidants and antimicrobial activities.
