    Author: Ntezurubanza L, Scheffer JJ, Svendsen AB.
    Journal: Planta Med; 1987 Oct; 53(5):421-3. PubMed ID: 17269059.
    Abstract:
    The essential oil of OCIMUM GRATISSIMUM, growing wild in Rwanda, was investigated by LSC, GLC, and GC-MS. The oil contained 35% thymol and 11% eugenol, which may indicate the occurrence of a new chemotype of the species. A large amount of hydrocarbons (42%) including 18% P-cymene was also found. The oil showed a relatively strong antimicrobial effect. The oil of O. GRATISSIMUM, cultivated in Rwanda from seeds collected in Cameroon, consisted of 47% thymol and only 0.3% eugenol. This sample contained 49% hydrocarbons, including 23% gamma-terpinene. Most of the constituents detected in the oil samples were not previously known to be present in the essential oil of O. GRATISSIMUM.
