Description Lippia alba cultivar ‘Kavach’ is an aromatic, multi-branched, trailing, deep-rooted shrub that can be planted on
slopes to control soil erosion. Cuttings of this genotype were planted on the edges of field plots developed by depositing agricultural soil on the rocky terrain of Aravalli mountain range land on which the Institute is located in New
Delhi. Shoots harvested several times a year in the third, fourth and fifth year from planting were sampled for leaves
and flowers bearing inflorescences to determine their biomass yield. The inflorescences and leaves sampled from the
harvests of third year were analyzed by GC and GC/MS for their oil quality. Altogether 55 compounds were identified
in leaf and inflorescence oils; a set of 47 compounds made up 96.3% of the leaf oil and 46 compounds made up 97.0%
of inflorescence oil. The concentrations of linalool and 1,8-cineole were 67.7% and 6.4% in the leaf oil, whereas these
were 79.3% and 5.2%, respectively, in inflorescence oil. The inflorescence oil also contained cis- and trans-linalool
oxides (2.8%). The importance of the flower oil of L. alba cultivar ‘Kavach’ as a linalool-rich oil resource is discussed
in terms of traditional sources of such oil and unique features of the cultivar.
The authors are grateful to the Director, Central Institute of Medicinal and Aromatic Plants (CIMAP), Lucknow for his cooperation in the GC/MS analyses and to the Director, NIPGR for providing facilities.
