The extracts obtained by 80% EtOH from some Asteraceae plants ( Calendula officinalis, Inula helenium, Arctium lappa, Artemisia absinthium and Achillea millefolium) were studied. Rosmarinic acid, one of the main compounds identified in all extracts, was determined quantitatively by using HPLC. In addition, spectrophotometric methods were evaluated as an alternative for rosmarinic acid content determination. Total phenolic content was also established for all extracts. A. millefolium extract was found to have the highest content of rosmarinic acid as well as total phenols. All extracts were tested for antioxidant and acetylcholinesterase inhibitory activity. A. millefolium was shown to possess the best antioxidant activity (for all tested methods) as well as acetylcholinesterase inhibitory activity. Highly positive linear relationships were obtained between antioxidant/acetylcholinesterase inhibitory activity and the determined rosmarinic acid content indicating its significance for the observed activities.

Lettuce (Lactuca sativa L.) is one of the most important leafy greens worldwide. The nutritional value of its edible leaf depends on different factors including type and growing conditions. The aim was to determine the bioactive compounds content, antioxidant activity and growth behavior of twenty-two lettuce genotypes, cultivated under field and greenhouse conditions. Total phenolic compound, chlorophylls, carotenoids, anthocyanin contents and antioxidant activities were analyzed by spectrophotometric methods. Data were analyzed by analysis of variance (ANOVA). Significant differences between bioactive compounds, antioxidant activity and growth behavior were found among cultivars and morphological types, for both growth conditions. Carotenoid and chlorophyll content was higher in greenhouse conditions for all genotypes. In field production, butterhead and iceberg lettuces showed lower content of these bioactive compounds. The red-pigmented Falbala cultivar from field production showed the highest level of polyphenols and anthocyanin. Meanwhile, in greenhouse conditions, the oak leaf cultivar Grenadine displayed the highest concentration of these phenolic compounds. The iceberg type lettuce showed the lowest percentages of antioxidant activity in both environments. The results showed the effect of growing conditions and the high variability in lettuce bioactive compounds content and antioxidant activity among the different types.
