“…The antioxidant activity in tested oil can be attributed to its chemical composition especially in the presence of linalool and menthol. This finding agrees with previous investigations 44,45 showing that extracts with highest polyphenol contents show higher antioxidant activity. These extractive phenolic compounds are among simple phenols and flavonoids.…”

To our knowledge, this study is the first to investigate the biological activities of the methanolic extracts of leaves, roots and stems of Ruta chalepensis L. (Rutaceae) in Tunisia. The chemical composition of the essential oil extracted from R. chalepensis leaves was determined by GC-MS. The antioxidant activities of tested essential oil and the methanolic extracts of leaves, stems and roots of R. chalepensis were evaluated using DPPH and ABTS radicals scavenging tests. Their antimicrobial activities were achieved by disc diffusion method and broth dilution assay. The main components of the selected essential oil were menthol (43.92 %) and linalool (42.10 %). Significant differences were found between the total phenol contents and biological activities of the different parts of R. chalepensis. In addition, significant correlations were observed between antioxidant activities and phenolic contents for methanol extracts. In fact, leaves extract presented higher total phenol content than stems and roots extracts. The tested oil showed better antioxidant activity than methanolic extracts. The highest antioxidant activity was recorded in leaves methanolic extract. The latter showed strong antibacterial activity against tested microorganisms, whereas the evaluated oil remained almost inactive. The inhibition zones diameters and minimal inhibitrice concentration values for tested bacteria, which were sensible to different methanolic extracts, were in the range of 8-35 mm and 0.78-25 mg/ml, respectively. This study demonstrated that the R. chalepensis extract can be regarded as promising candidate for natural plant source of antioxidant and antimicrobial agents.

“…In Tunisia, A. herba-alba is growing wild in the southern arid zone [38]. Moreover, the wormwood or absinthe wormwood, Artemisia absinthium L., is a medicinal and aromatic bitter herb, which has been used as a medicine from ancient times [39]. Artemisia species essential oils have insecticidal or repellent properties [40][41][42][43][44].…”

“…Curcuma longa, A. absinthium and S. lappa are commonly known as Haldi, Afsantheen and Kust, respectively in Pakistan. These herbs are enriched in biological active chemicals like C. longa, A. absinthium and S. lappa reported for curcumin, thujone and germacra-1,4,11-trien-12-oic acid, respectively (de Kraker et al, 2011;Liu et al, 2012;Riahi et al, 2013). Sporulation inhibition is a common criterion to assess the anticoccidial properties (Molan et al, 2009).…”

Effect of leaves of Curcuma (C.) longa, seeds of Artemisia (A.) absinthium and roots of Saussurea (S.) lappa was evaluated on sporulation of Eimeria (E.) tenella under laboratory conditions. The oocysts used in this study were obtained by challenging the 14 th day-old broiler chicks with 75,000 sporulated oocysts of E. tenella. The harvested oocysts were exposed to various doses of the 70% aqueous-methanolic herbal extracts (0.244-500 µg mL -1 ). The oocysts were provided 27.5 o C temperature with 60-80% humidity and continuous aeration. The yield (w/w) of C. longa, A. absinthium and S. lappa, was 46.2, 45.9 and 47.5%, respectively. Inhibition of sporulation was criterion for evaluation of the efficacy. The herbal extracts exhibited graded dose response on sporulation of E. tenella as evident by their lethal concentration (LC 50 ) values. LC 50 values of C. longa, A. absinthium and S. lappa were 173.4, 221.3 and 960.6 µg mL -1 , respectively. C. longa demonstrated the highest inhibitory effects on sporulation of E. tenella oocysts.
