Cistus Cistaceae

As part of a study of the secondary chemistry of members of Cistus (the rock-rose) in France, Robles and Garzino (1998) examined the essential oil of C albidus L. Plants were sampled from two areas in Provence characterized by different soil types, calcareous sites west of Marseille, and siliceous sites near Pierrefeu-du-Var and Bormes les Mimosas (PF and BM, respectively, in Fig. 2.23), which lie about 60 km and 80 km to the east, respectively, in the Massif les Maures. Regardless of the soil type, a-zingiberene [88] (Fig. 2.24) was the dominant component. Concentrations of other major components of the plants varied between the two soil types, as summarized in Table 2.6. Many other compounds were present in lesser amounts, but varied little between the two areas. A more recent paper by the same workers (Robles and Garzino, 2000) described an analysis of C. monspeliensis L. leaf oils, the results of which are summarized in Table 2.7. 

Additional information on essential oil variation in C. monspeliensis comes from a study by Angelopoulou et al. (2002) who were interested in diurnal and seasonal patterns. Significant differences were noted during both time periods. It would be of interest to learn what effects cultivation in a common garden enviromnent would have on oil expression in these species.

The plants that exude diterpenoid resins belong to the order of conifers. Pine resins (from the Firms genus), Strasburg turpentine (from the Abies genus), Venice turpentine (from Larix decidua) were extracted from Pinaceae. Sandarac, juniper and cypress resins were extracted from trees of the Cupressaceae family Tetraclinis articulata, Juniperus spp. and Cupressus semprevirens, respectively. Moreover, labdanum resin from the Cistaceae family (Cistus spp.) also belongs to the diterpenoid resins.
