Twenty-one compounds were submitted to multivariate statistical analyses using Principal Component Analysis (PCA). Factorial Discriminant Analysis (FDA) revealed the presence of three chemotypes. Chemotype I is already known (1,8-cineole; 50%), chemo-type II had an equal content in 1,8-cineole (33%) and viridiflorol (32%). The third (chemotype III) was characterized by a high content in viridiflorol (50%). The 1,8-cineole chemotype represented 58% of three populations. Seasonal differentiation does not occur, showing that Niaouli oil composition is stable all year.

Composition of essential oil of bidens cernua L., asteraceae from Serbia / Jean-Claude Chalchat in The journal of essential oil research, Vol. 21 N°1 (Janvier/Février 2009)

By GC and GC/MS analysis, 16 components were identified (70.1% of the total oil). The plant material yielded 0.5% (v/w) of gold-yellowish liquid with intensive, unpleasant and heavy scent. The principal compound was identified as 1-phenylhepta-1,3,5-triyne (57.1%), followed by sesquiterpenes caryophyllene oxide, humulene-1,2-epoxide and α-selinene (3.0%, 3.1% and 1.1% respectively), as well as (E,E)-1,3,11-tridecatriene-5,7,9-triyne (1.8%).

The essential oil contents were 1.21% (v/w) in flowers, 0.64% (v/w) in leaves, 0.08% (v/w) in stems and 0.24% (v/w) in rhizome. By GC and GC/MS analysis, in all four oils the total of 132 compounds was identified: 53 constituents (93.4% of total amount) in the oil obtained from the flowers, 70 (94.3% of total amount) in the oil from the leaves, 78 (87.8% of total amount) in the oil from the stems and 67 (95.9% of total amount) in the oil from rhizome. In all oils investigated, monoterpenes were the dominant class of constituents (73.9–83.7%), with hydrocarbons (65.6–81.6%) as the most abundant representatives. Limonene, α-pinene and sabinene were identified as the most important constituents in common for all four oils. In the oil from the flowers, leaves and stems, β-pinene and myrcene were also abundant. However, the flower oil differed from the others by a significant quantity of α-phellandrene.
