Chemical Compositions and Antimicrobial Activity of Essential Oils of Schisandra henryi subsp. hoatii from Vietnam.

However, monoterpene hydrocarbons (34.7%), oxygenated monoterpenes (4.7%), sesquiterpene hydrocarbons (49.8%), oxygenated sesquiterpenes (7.7%), and nonterpenes (1.4%) were the classes of compounds identified in the stem essential oil of I S. henryi i subsp I . hoatii i . However, the compositions of essential oils from other I Schisandra i plants have been described - essential oil from the berries of I S. chinensis i are comprised of I i I cis i -bergamotene (10.7%), selina-4,11-diene (5.2%), and I i -cadinol (5.1%), while the ylangene (10.1%), I i -himachalene (9.4%) and I di i I epi i I i -cedrene (8.9%) were found in the seed oil. The identities of these terpenes differ from species to species - for example, I i -ylangene, I cis i I i -bergamotene and I di i I epi i I i -cedrene, the major compounds of I S. chinesis i [[2]], were conspicuously absent in I S. henryi i subsp I . hoatii i essential oils. However, the fruit essential oil of I S. chinensis i isolated by simultaneous distillation extraction (SDE) showed good antibacterial activity against both Gram-positive ( I S. epidermidis i , I S. aureus i , I B. subtilis i ) and Gram-negative ( I E. coli i , I P. aeruginosa i , I Proteus vulgaris i ) bacteria [[3]].
