Evaluating the potential of Lavandula × intermedia 'Budrovka' as a source of polyphenolic compounds
Lavandula × intermedia 'Budrovka' is a Croatian indigenous cultivar of lavandin, cultivated on a large scale mainly for its essential oil used in cosmetic and pharmaceutical industries. Whereas many aromatic plants belonging to the Lamiaceae family are very rich in polyphenolic compounds, the present study focused on qualitative and quantitative evaluation of lavandin 'Budrovka' as a source of different types of polyphenols (phenolic acids, flavonoids, anthocyanins, procyanidins and tannins). In this regard, the contents of analysed compounds were spectrophotometrically determined in leaves, inflorescence stalks and flowers during the various stages of growth and monitored for three years. The obtained results revealed significant differences in polyphenols quantities among individual plant parts as well as important influence of harvesting time on them. Overall, hydroxycinnamic acids were the predominant phenolic group in all plant parts. The highest amounts, ranged from 3.89% to 4.93% across the three-year period, were found in leaves where the maximal accumulation was observed in the vegetative stage (4.77-4.93%). The flowers collected in the early flowering stage were also rich in phenolic acids (4.32-4.94%), but their amount decreased significantly (p0.001) with inflorescence development and at the end of flowering reached 2.30-2.60%. The inflorescence stalks contained 1.00-2.05% of phenolic acids with peak amounts observed at the beginning of flowering period. Flavonoids occurred most abundantly in leaves (0.16-0.24%), while lower contents were determined in inflorescence stalks (0.10-0.13%) and flowers (0.04-0.10%). Our findings suggested that leaves and flowers of Croatian cultivar of lavandin are rich sources of polyphenolic compounds having the potential to offer a wide range of health benefits.
