“…Carbohydrates are the main metabolites of primary metabolism, and their synthesis is affected by the photosynthesis rate 34 . Thus, the production of terpenoids in plants is directly linked to photosynthesis and, consequently, the biosynthesis of related precursor metabolites 35 . Zhang et al 35 demonstrated that the increase in the photosynthetic capacity of Glechoma longituba leaves under the influence of blue and green lights enhanced TTAs accumulation in this plant.…”

Viscum album L. (mistletoe) is a semiparasitic plant of the Santalaceae family. A valuable group of bioactive compounds in mistletoe are triterpene acids (TTAs), which possess anti-inflammatory and anticancer properties. Parrotia persica and Carpinus betulus are the most common hosts of mistletoe in the Hyrcanian forests of Iran. This study was performed to compare the content of oleanolic acid (OA), betulinic acid (BA), and ursolic acid (UA) in the mistletoe foliage (stems and leaves) from P. persica and C. betulus in various seasons for the first time. The results showed that OA was the prevailing TTA in all samples, while UA was found in none of them. The maximum amount of OA (12.38 mg/g dry weight [DW]) and BA (1.68 mg/g DW) was detected in V. album from P. persica in summer. The minimum amount of OA (5.58 mg/g DW) and BA (0.72 mg/g DW) was observed in that growing on C. betulus in winter. However, the mistletoe from C. betulus showed the greatest level of OA in spring (9.06 mg/g DW) and BA in summer and autumn (0.92 and 0.97 mg/g DW, respectively). The data collected in this study complement existing research on this subject from around the world.
