Transcriptome analysis approaches for the isolation of trichome-specific genes from the medicinal plant Cistus creticus subsp. creticus.

Cistus creticus subsp. creticus is a plant of intrinsic scientific interest due to the distinctive pharmaceutical properties of its resin. Labdane-type diterpenes, the main constituents of the resin, exhibit considerable antibacterial and cytotoxic activities.

A simple and rapid method for the differentiation of C-13 manoyl oxide epimers in biologically important samples using GC-MS analysis supported with NMR spectroscopy and computational chemistry results.

There is confusion in the literature related to the characterization of biologically important C13 manoyl oxide epimers by using their mass spectrometric data. Furthermore a method for calculating the epimeric purity has not been established. In this work mixtures of manoyl oxide C13 epimers and pure ent-13-epi-manoyl oxide have been isolated from plant extracts.

A chemometric interpopulation study of the essential oils of Cistus creticus L. growing in Crete (Greece).

The chemical composition of the essential oils of twenty-five populations of Cistus creticus subsp. creticus L. from the island of Crete (Greece) and their interpopulation variability were analysed in detail by GC-MS.
