Mistletoe (Viscum album L.) from Santalaceae family is a hemiparasitic plant containing triterpene acids which widely was used as complementary remedy in cancer therapy for decades. Mistletoe is growing on various tree species as well as some endemic and native species of Hyrcanian forests of Iran such as Parrotia persica (Persian ironwood) and Carpinus betulus (Hornbeam). The aim of this work was to compare the amount of triterpene acids including oleanolic acid (OA), betulinic acid (BA) and ursolic acid (UA) in foliage (leaves and stems) and fruit of mistletoes settled on P. persica and C. betulus as hosts in autumn. In this study, mistletoe plant parts were collected from three bases of each host species in Daeiz forest of Hyrcanian forests of Iran. The samples were extracted with ethyl acetate and analyzed by HPLC. The results indicated that the host species had no significant effect on the amount of triterpene acids in the mistletoes. But the organ type (foliage and fruit), had significant effect on the BA content meanwhile it didn't show any significant effect on the OA. The highest level of BA was significantly detected in foliage of mistletoes on P. persica and C. betulus (1.23 and 0.97 mg/g dry weight) respectively. Independence of statistical analysis, the highest content of OA (8.52 mg/g dry weight) was observed in the foliage of V. album on P. persica. On the other hand, BA was not detected in mistletoe fruits on both host species. UA was not detected in any samples. • The highest amount of betulinic acid with significant difference was found in the foliage of Viscum album. • The highest amount of oleanolic acid was detected in the foliage of Viscum album on Parrotia persica and Carpinus betulus. • Oleanolic acid was the dominant triterpene acid in the foliage and fruit of this plant on both studied host species.
