The hydrocarbons of pepper essential oil. Debrauwere J, Verzele M. Twenty-six hydrocarbons were identified in the essential oil of black pepper. Three of these are sesquiterpenes which have not been reported previously as occurring in this oil (beta-cubebene, alpha-guaiene and gamma-cadinene). Some other hydrocarbon constituents mentioned in the literature were absent in our pepper oil.

DOCUMENT TYPE: Journal CA Section: 11 (Plant Biochemistry) The supercrit. fluid extn. (SFE) method for extg. piperine from Fructus piperis Longi was presented. The extd. piperine was detd. by HPLC. SFE conditions were as follows: pressure 38.5 MPa, temp. 70°, 0.4 mL methanol as a modifier, static extn. 5 min, and dynamic extn. vol. 5 mL. The results showed that SFE was a quick, accurate, and high efficiency extn. method. ------------------------------------------------------------------------------------------ http://www.ots.duke.edu/tropibiojnl/claris/44-2/!CICCI~1.HTM REFERENCIAS Atal, C.K., K.L.
