| "P.undulatum flowers are known for their jasmine-like odour... Essential oil samples were isolated from the (deep-frozen) aerial parts by hydrodistillation to estimate the oil yields, and by distillation–extraction to determine their percentage composition, and analysed by GC and GC-MS. Monoterpenes (59-97%) were dominant in all oils, sabinene (5-58%), limonene (2-37%) and terpinen-4-ol (4-27%) being the major components, although in different relative amounts during the year of collection. Benzyl benzoate (8%) and benzyl salicylate (10%) attained high relative amounts in the oils from fully developed flowers, whereas in the oils from the other plant parts their relative amounts did not exceed 1%." \\ | "P.undulatum flowers are known for their jasmine-like odour...
