The aim of the study was to study tocopherols in the fruits of various sea buckthorn ecotypes ssp. mongolica in comparison with other subspecies. The composition of tocopherols in fruit pulp of four subspecies of sea buckthorn – H. rhamnoides ssp. mongolica, ssp. turkestanica, ssp. fluviatilis and ssp. carpatica, growing at Lisavenko Research Institute of Horticulture for Siberia in forest-steppe conditions of Altai territory has been studied. The research has been focused on the most promising subspecies from the point of view of industrial utilization – H. rhamnoides ssp. mongolica, in order to identify possible variation in accumulation of different tocopherols in fruit pulp depending on ecotype, period of collection of fruits as well as conditions of the year.
It was established that the major tocopherol in the pulp of the fruit of sea buckthorn is α-tocopherol. β -, γ-and δ-tocopherols were characterized by low content. Within subspecies H. rhamnoides ssp. mongolica most fractions of tocopherols (except δ-tocopherol) have relatively high coefficient of variation, which exceeds of that for the whole group of evaluated varieties. That result does not allow us to use this criteria as a reliable background for preliminary systematic identification of evaluated varieties.
