Özet:

 This study investigates the effects of harvest time and plant parts on the concentrations of essential oils, phenolic content, flavonoids, and antioxidant activities ABTS and DPPH in the Lippia citriodora plant to determine the best outcome. The experiment consists of four different harvest times during flowering period and two plant parts upper and lower. Harvest times were scheduled at weekly intervals.Significant variations were observed during experiment, Essential oil EO content reached peak value at the first harvest in upper parts of plants L1U: 1.18 and lowest value in lower parts by the fourth harvest L4L: 0.25. The highest phenolic content determined at the first harvest L1: 44.04 mg GAEg DW, while flavonoid levels reached peak value at the fourth harvest L4: 314.07 mg ruting DW. Antioxidant activities, measured by ABTS and DPPH assays, were significantly greater in lower plant parts. Partial Least Squares Discriminant Analysis PLS-DA and Principal Component Analysis Discriminant Analysis PCA-DA confirmed clear distinctions between the upper and lower parts of the plant regarding bioactive compounds concentrations. The findings shows the importance of targeted harvest timing and plant parts in optimizing bioactive compound in Lippia citriodora, with implications for getting better benefits from plant.
