Nanotechnology is an escalating field, which has an growing impact in each and every sector. There are many ways for synthesizing nanoparticles but biosynthetic route of nanoparticle synthesis is emerging as a new and safer alternative to the conventional methods. Ocimum basilicum Lamiaceae (OBL) is an age old herb native to Southeast Asia and Central African countries. These plants are generally known to be used in different cuisines worldwide. The aroma emitted from the leaves and the twigs of the fresh and dried plants are well known to have insect repellent property. Estragole, citronellal, limonene and nerolidol are the natural volatile compounds present in the basil leaves which acts as repellents. This plant is also widely used as a scent through which it netted its title Queen (basileus) of aromatic herbs. In present study the Green synthesis of some metal oxide nanoparticles have been synthesized by Ocimum Basilicum-Lamiaceae (Thiru Neetru Pathilai).
