Thirty-five compounds representing 98.3% of the oil were identified. Si-gel chromatography of the oil yielded 2-hydroxyacetophenone, which was characterized by spectral methods (1H-, 13C-NMR and mass), as the main component, amounting to 89.5% of the oil.

Analysis of linalool content in the inflorescence (Flower) essential oil and leaf oil of lippia alba cultivar ‘Kavach’ / Raghvendra K. Mishra in The journal of essential oil research, Vol. 22 N° 1 (Janvier/Fevrier 2010) 

Public ISBD [article]  in The journal of essential oil research > Vol. 22 N° 1 (Janvier/Fevrier 2010) . - pp. 3-7 Titre : Analysis of linalool content in the inflorescence (Flower) essential oil and leaf oil of lippia alba cultivar ‘Kavach’ Type de document : texte imprimé Auteurs : Raghvendra K. Mishra, Auteur ; Swati Chaudhary, Auteur ; Richa Pandey, Auteur Article en page(s) : pp. 3-7 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Lippia  alba  Verbenaceae  Essential  oil  composition  Linalool Index. décimale : 646 Résumé : 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.
