The Effect of Pre-Harvest Treatments with Tanacetum vulgare L. and Satureja montana L. Essential Oils (EOs) on the Yield and Chemical Composition of Aronia melanocarpa (Michx.) Elliot Fruit

Abstract

Tanacetum vulgare and Satureja montana essential oils (EOs) on Aronia melanocarpa before the flowering period were used against Acrobasis advenella. We hypothesised that the use of the aforementioned EOs (1.5%, 3% and 4.5%) would simultaneously improve yield and fruit quality. The profile of the EO constituents was determined by GC-MS analysis. Thujone (66.62%) was identified as the most abundant component in tansy EO, while thymol (40.04%) was dominant in savory EO. The mean weight of 100 berries ranged from 82.40 g to 88.00 g. A loss in fruit weight was recorded after the addition of 4.5% S. montana EO. A. melanocarpa shrubs treated with 4.5% tansy EO showed the highest content of phenols (848.03 mg per 100 g FW), along with high levels of anthocyanins (310.19 mg/100 g), tannins (1884 mg/100 g) and chlorogenic acid (187.38 mg/100 g) but exerted negative effects on the mineral fruit content (Mg, K). T. vulgare oil, particularly at higher concentrations, has shown promise for increasing the content of valuable compounds with strong antioxidant properties. The application of S. montana EOs positively affected minerals and chlorogenic acid content. However, their phytotoxic effects on A. melanocarpa preclude them from further use, even at low concentrations.

Phytochemistry and Allelopathic Effects of Tanacetum vulgare L. (Tansy) Extracts on Lepidium sativum L. (Garden Pepper Cress) and Lactuca sativa L. (Lettuce)

“…The effectiveness of T. vulgare essential oils was revealed against Acrobasis advenella in improving the yield and fruit quality of Aronia melanocarpa (Michx.) Ellio [24]. The in vitro anthelmintic activity of various tansy inflorescence and leaf extracts was estimated on Trichostrongylidae nematodes in sheep [25].…”

“…Numerous recent investigations focused on tansy volatile compounds and essential oils [1,3,6,8,12,13,22,27,[35][36][37][38][39][40]. The phytochemical analyses of the plant extracts revealed that it contains flavonoids, tannins, phenolic compounds, carotenoids, and their derivatives [2,4,6,7,[9][10][11][12]16,24].…”
