Vk. Kaul et Sk. Vats, ESSENTIAL OIL COMPOSITION OF BOTHRIOCHLOA-PERTUSA AND PHYLETIC RELATIONSHIP IN AROMATIC GRASSES, Biochemical systematics and ecology, 26(3), 1998, pp. 347-356
Chemical composition of the essential oil of Bothriochloa pertusa (L)
A. Camus, collected from temperate Himalaya, revealed the major catego
ries of terpenoids as monoterpene hydrocarbons (26.45%), oxygenated mo
noterpenes (7.29%), sesquiterpene hydrocarbons (4.73%) and oxygenated
sesquiterpenes (37.05%), in 82.31% of the total volatile constituents
identified. Twenty-eight compounds were identified, the major of which
are camphene (7.40%), limonene (14.90%), borneol (2.26%), Isobornyl a
cetate (2.01%), beta-caryophyllene (3.10%), intermedeol (24.72%) and a
corenone-B (9.80%). B. pertusa contains higher percentage of monoterpe
ne hydrocarbons and oxygenated monoterpenes in comparison to B. bladhi
, the only other species of the genus analysed in detail. About 88% of
the aromatic grasses are represented by tribe Andropogoneae, that spr
ead globally by late Miocene, possibly a period of the greatest evolut
ionary diversity in aromatic grasses. (C) 1998 Elsevier Science Ltd. A
