Some of the volatile metabolites of eight species of blue-green algae of the genera Oscillatoria, Phormidium, Aphanizomenon, and Anabaena were identified by gas chromatography mass spectrometry (GC-MS). As a result, five sesquiterpene alcohols (C15H26O) and two sesquiterpene hydrocarbons (germacrene-D and γ-cadi-nene) were detected in the cultures of Oscillatoriasplendida. O. amoena, and Anabaenamacrospora. Three aliphatic hydrocarbons (n-heptadecane,1-heptadecene and 7-methylheptadecane) were also identified in the cultures of most of these algae. None of these compounds appeared to impart an unpleasant taste or odor to water supplies.

Minor Compounds

The composition of the essential oils of Murraya koenigii(L.) Spreng, cultivated at six locations in Peninsula Malaysia and Borneo are presented. The oils were obtained from fresh leaves by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS); 61 compounds were identified, of which eleven were present in all the specimens analyzed. The two major volatile metabolites were identified as β-caryophyllene (16.6-26.6%) and α-humulene (15.2-26.7%) along with nine minor compounds identified as β-elemene (0.3-1.3%), aromadendrene (0.5-1.5%), β-selinene (3.8-6.5%), spathulenol (0.6-2.7%), caryophyllene oxide (0.7-3.6%), viridiflorol (1.5-5.5%), 2-naphthalenemethanol (0.7-4.8%), trivertal (0.1-1.0%) and juniper camphor (2.6-8.3%). The results suggest that β-caryophyllene and α-humulene could be used as chemotaxonomical markers for Malaysian M. koenigii, hence these specimens could be of the same stock and different from the ones in India, Thailand and China.
