Composition of absolutes of jasminum sambac L. flowers fractionated with liquid CO2 and methanol and comparison with liquid CO2 extract / P. K. Rout in The journal of essential oil research, Vol. 22 N° 5 (Septembre/Octobre 2010)

Direct extraction of flowers with liquid CO2 gave a relatively fat-free and superior product in 0.44% yield. It was found that the CO2 method of fractionation of pentane extract is a practical process providing an organoleptically superior product, though the product is not totally free from waxy substances. (E,E)-α-Farnesene and (Z)-3-hexenyl benzoate, along with compounds like indole, methyl anthranilate and methyl jasmonate, responsible for high diffusivity of the jasmine fragrance, have been obtained with improved recoveries in the CO2 fractionated concrete.

Essential oil composition of cymbopogon microstachys (Hook.) soenarke occurring in manipur / P. K. Rout in The journal of essential oil research, Vol. 17 N° 4 (Juillet-Août 2005)

The results showed that the oil contained (E)-methyl isoeugenol (56.4–60.7%) as the major constituent. This is the first time that an oil of C. microstachys has been found with (E)-methyl isoeugenol as the major constituent.
