Summary: Curcuma aff aeruginosa Roxb. and Curcuma zedoaria (Berg.) Rose,
Zingiberaceae, have been used in Vietnamese folk medicine. The petroleum ether and the benzene extracts from the rhizomes of C. aff. aeruginosa inhibited the growth of ihe pathogenic microorganisms Escherichia coli, Pseudomonas aeruginosa. Salmonella typhi, Serratia mascenscen, Enterobacter cloaceae, Klebsiella pneumoniae, and Staphyllococcus aureus. Fourteen sesquiterpene hydrocarbons and eight oxygenated sesquiterpenoids were identified in the extract among which furanodiene, (E,E)-germacrone, furanodienone. curdione, curzerenone, curcumol and curcumenol. Curdione was effective against E. coli, S. typhi, K. pneumoniae and S. aureus, ne petroleum ether extract from the rhizomes of C. zedoaria was active against B. cereus and S. lutea whereas the eihyl acetate extract inhibited the growth of B. cereus, S. lutea, S. aureus and S. typhi. Ten sesquiterpetioids were found in the petroleum ether extract among which humulene, zerumbone, zerumbone'2,3-epoxide and new humulene-8- hydroperoxide were isolated.

Flavour and Fragrance Journal, 14, 219-224.
Summary: The very pleasant (flowery, hay- and tea-like, woody) smelling
essential oil of the flowers of Aglaia odoraia Lour. (Meliaceae) consists mainly of cadinane derivatives (ca. 48%, including 27% of S-cadinene). A main constituent is muurola-4,10(14)-dien-lj3-ol (4%), accompanied by the new epimeric la- alcohol. Methyl jasmonates (4%) obviously make an important odour contribution.

Summary: The essential oil from the fruits of Zanthoxylum rhetsoides Drake
(syn. Z. myriacanthum Wall, ex Hook, f) of north-west Vietnamese origin consists of 78% of monoterpene hydrocarbons, 19% of oxygenated monoterpenes, 1% of n-aicohols and only 1% of sesquiterpenes. The essential oil from aerial parts of Zanthoxylum alatum Roxb. (syn. Z. armaium DC, Z platiispinium Sieb. et Zucc.) collected in north-west India contains 33% of monoterpene hydrocarbons. The main constituents are 1,8-cineole (15.7%), linalol (18.8%) and undecan-2-one (17.0%).
