D. Angelopoulou et al., An interpopulation study of the essential oils of Cistus parviflorus L. growing in Crete (Greece), BIOCH SYST, 29(4), 2001, pp. 405-415
The composition of the essential oils of nine populations of Cistus parvifl
orus L., from Crete (Greece) and their interpopulation variability, were in
vestigated by GC-MS. 114 compounds were identified representing an average
of 85-96% of oil composition. Labdane diterpenes were detected and identifi
ed in the essential oils of Cistus parviflorus L. for the first time. The r
esults obtained From GC-MS analysis of the Volatile oils were submitted to
principal component and chemometric cluster analysis. Two main chemotypes (
clusters) were differentiated: the first of West Crete and the second of Ea
st Crete. Carvacrol, caryophyllene oxide, alpha -epi-cadinol, abietatriene,
4-epi-dehydroabietol, dehydro abietol, cis-ferruginol and manoyl oxide mix
ture of isomers are the main constituents, while oxygenated sesquiterpenes
as well as diterpenes have been found in high percentage composition. (C) 2
