Further comparison with the leaf oils of L. guatemalensis [9] and L. laevigate [6] showed that the compounds of L. laevigate [6] were predominantly monoterpenoids and, therefore, differed from the leaf oils of L. mushaensis and L. linii.…”

The hydrodistilled essential oils of the leaves and twigs of Litsea mushaensis and L. linii were analyzed. Sixty-nine and ninety compounds were identified in the leaf and twig oils, respectively, of L. mushaensis. The main components of the leaf oil were β-eudesmol (24.2%), τ-cadinol (10.2%), α-humulene (10.1%), α-pinene (9.7%), and trans-β-ocimene (6.5%), whereas the main components of the twig oil were trans-β-ocimene (19.5%), α-pinene (12.8%) and cis-β-ocimene (7.7%). With L. linii, 72 and 78 compounds were respectively identified in the leaf and twig oils. The main components of the leaf oil were β-selinene (15.7%), α-selinene (15.5%), β-caryophyllene (12.2%), α-humulene (7.2%), and δ-cadinene (5.6%), and of the twig oil trans-β-ocimene (20.8%), β-selinene (11.4%), α-cadinol (6.0%), δ-cadinene (5.8%), τ-cadinol (5.4%) and β-eudesmol (5.2%). L. mushaensis leaf oil was shown to have excellent antimicrobial and anti-wood-decay fungal activity, superior to the other oils.

Introduction The Lauraceae family is by far the largest family of the order Laurales with about 50 genera and over 2000 species distributed throughout tropical to subtropical latitudes especially in Southeast Asia and tropical America. 1 Several genera have a pantropical distribution such as Beilschmiedia, Cassytha, Cryptocarya, Litsea, Ocotea, and Persea. Others are restricted to Asia and Australia which are Alseodaphne, Dehaasia, Endiandra, Eusideroxylon, Hexapora, and Neolitsea. Eusideroxylon is restricted to Borneo and Sumatra while Dehaasia and Hexapora are restricted to Peninsular Malaysia. Besides, Ravensara and Potameia can be found in Madagascar. 2-3 The Lauraceae family can be recognized by its distinctive floral morphology. The bark is smooth, leathery, and has many lenticels. The inner bark is fragrant, yellow, orange, reddish, or pinkish and exudes a pale yellow to pale brown sap after incision. The leaves in this family are simple, without stipules, opposite, spiral, whorled or alternate, usually with several gland dots and often release aromatic scent when crushed. The inflorescences are racemose or in clusters. The flowers are bisexual, actinomorphic, small, regular, greenish-white or yellow, fragrant,

This study analyzed the hydrodistilled essential oils in the leaves and twigs of Litsea akoensis to determine composition and yield. Seventyone and 40 compounds were identified in the leaf and twig oils, respectively. The main components of leaf oil were limonene (18.5%), thymol (10.1%), p-cymene (9.6%), -caryophyllene (8.9%), and carvacrol (8.2%). The main components of twig oil were -phellandrene (43.7%) and trans--ocimene (10.4%). The results demonstrated that leaf oil had excellent antioxidant and antimicrobial activities, superior to those of twig oil.
