Volatile flower oils of three genotypes of rose-scented geranium (Pelargonium sp.)

The volatile flower oils of three genotypes of rose-scented geranium (Pelargonium sp.) commercially cultivated at a high altitude (2200 m above MSL) location (Kodaikanal) in India were investigated by GC and GC–MS. Freshly collected flowers of genotypes 1, 2 and 3 on distillation produced oil yields of 0.32%, 0.34% and 0.50%, respectively. The flower oil of genotype 1 was richer in α-pinene (1.7%), (Z) and (E)-rose oxides (1.3% and 0.6%),...
