Thailand Abstract: The essential oils
obtained by hydrodistillation from the leaves of Litsea cubeba Per., fruits
of L. glutinosa C.B. Robinson,
leaves and bark of L. petiolata Hoof f. (Lauraceae) were
examined by GC/MS to determine their chemical composition. Examination of chemical constituents
of essential oil from three Litsea species, it was found that the major
components was present specifically in individual species. They were sabinene in L. cubeba,
(E)-(-ocimene in L.. glutinosa, , (E)-cinnamaldehyde (leaves) , (E)-
nerolidol (bark) in L. petiolata.
In addition , it was found that
the essential oilsof L.
cubeba (leaves) showed antimicrobial activity against Staphylococcus aureus ATCC 29213 ( Gram
positive bacteria). The oil of
L. glutinosa (fruit) and L.
petiolata (bark) exhibited strong antimicrobial activity against Candida albicans ATCC 10231 (yeast). ·ÕèÁÒ : Ç··. 18-20 µ.¤. 2543 |
