Essential oils from peels of 6 citrus species were extracted. The species were
lemon (Citrus limon), orange (C. sinensis), grapefruit (C. paradisi), pomelo
(C. maxima), mandarin (C. reticulata) and bitter lemon (C. aurantium) using
hydro-distillat
ion (Clevenger type).
In general Gram-positive bacteria were more sensitive to the oil
extracts tested than Gram-negative bacteria, and P. aeruginosa was the most
sensitive within the Gram-negative group.
