“…For centuries, indigenous plants have been used in herbal medicine for curing various diseases [6]. Recently, the acceptance of traditional medicine as an alternative form for health care and the development of microbial resistance to the available antibiotics has led authors to investigate the antimicrobial activity of medicinal plants [7,8].…”

Essential oil obtained by hydrodistillation and two different solvent extractions (petroleum ether and ethanol) from five Zingiberaceae species: ginger (Zingiber officinale Roscoe.), galanga (Alpinia galanga Sw.), turmeric (Curcuma longa L.), kaempferia (Boesenbergia pandurata Holtt.) and bastard cardamom (Amomum xanthioides Wall.) was characterized. Volatile components of all extracts were analyzed by gas chromatographymass spectrometry (GC-MS). The major components of ginger, turmeric, galangal, bastard cardamom and kaempferia were zingiberene, turmerone, methyl chavicol, and γ-terpinene, respectively. Their antibacterial effects towards Escherichia coli, Staphylococcus aureus, Bacillus cereus and Listeria monocytogenes were tested by a disc diffusion assay. Essential oil of kaempferia and bastard cardamom obtained by hydrodistillation extraction could inhibit growth of all tested bacteria. Essential oil of ginger extracted by hydrodistillation had the highest efficiency against three positive strains of bacteria (S. aureus, B. cereus and L. monocytogenes), with a minimum concentration to inhibit B. cereus and L. monocytogenes of 6.25 mg/mL.

Based on ethnopharmacological information, four different varieties of seeds were obtained from authentic seed suppliers. Ethanol, methanol, acetone, chloroform and petroleum ether seed extracts were assessed for antibacterial activity against wound isolates of Multi Drug Resistant -Methicillin Resistant Staphylococcus aureus (MDR-MRSA). Ethanol, methanol and acetone extracts of Moringa oleifera, Elettaria cardamomum and Tamarindus indica seeds showed more effective anti MRSA activity than Artocarpus heterophyllus. In addition Moringa oleifera seed extracts may have the potential to restore the effectiveness of -lactam antibiotics against MRSA.

“…Also, the n-hexane extract was much less active than the MeOH and DCM extracts. 39 Tawaha et al 40 determined the relative levels of antioxidant activity and the total phenolic content of aqueous and methanolic extracts of a total of 51 Jordanian plant species. They indicated that the aqueous and methanolic extracts of R. lutea had remarkably high total phenolic contents and showed good levels of antioxidant activity.…”

ÖZAmaç: Bu çalışmada Diplotaxis tenuifolia ve Reseda lutea'nın çiçek ve yapraklarından elde edilmiş olan metanol özütlerinin AR, CAT, GST ve GPx enzimlerinin aktiviteleri üzerinde olan etkilerinin araştırılması amaçlanmıştır. Gereç ve Yöntemler: Bu çalışmada, bitki örneklerinin toplam fenolik ve flavonoid içeriği; Folin-Ciocalteu ve alüminyum klorür reaktiflerinin yardımıyla kolorimetrik yöntemlerle değerlendirilmiştir. Ayrıca özütlerin CAT, GST, GPx ve AR enzimlerinin aktiviteleri üzerindeki etkileri kinetik analizler ile araştırılmıştır. Bulgular: En yüksek miktarda fenolik ve flavanoid içeriği sırasıyla 144.49±0.29 mg gallik asit eş değeri/L ve 250.485±0.002 quercetin eş değeri/L tespit edilmiştir. GST ve GPx için en iyi aktivite profilleri sırasıyla 121±0.05 ve 140±0.001 ng/mL IC 50 değerleri ile D. tenuifolia yaprak özütünde gözlemlenmiştir. Elde edilen sonuçlara göre, R. lutea ve D. tenuifolia'nın yapraklarından elde edilen metanol özütleri, AR enzimi üzerinde önemli ölçüde bir aktivite potansiyeli göstermemiştir. Bununla beraber, çalışılmış olan çiçek ve yaprak özütlerinin hiçbiri yeterli düzeyde CAT aktivasyonu gösterememiştir. Sonuç: Çalışma sonucunda, D. tenuifolia'nın yapraklarının antioksidan enzimatik savunma sistemi üzerinde iyi bir etkiye sahip olduğu gösterilmiştir. Bu sebeple günlük diyet için iyi bir besin kaynağı olarak kabul edilebilir.

Materials and Methods: Total phenolic and flavonoid contents of the plant samples were evaluated using Folin-Ciocalteu reagent and aluminum chloride colorimetric methods. Also, the effects of extracts on CAT, GST, GPx, and AR enzyme activities were investigated using kinetic assays. Results: The highest phenolic and flavonoid contents were detected in the methanol extract of D. tenuifolia leaves with 144.49±0.29 mg gallic acid equivalent/L and 250.485±0.002 quercetin equivalent/L, respectively. The best activity profile for GST and GPx were observed in the extract of leaves belonging to D. tenuifolia with IC 50 values of 121±0.05 and 140±0.001 ng/mL, respectively. According to the results, methanol extracts from leaves of R. lutea and D. tenuifolia showed no significant activity potential on AR. Moreover, none of the studied extracts demonstrated any reasonable CAT activation potential. Conclusion:The results indicated that leaves of D. tenuifolia had good effect on the antioxidant enzymatic defense system, which it makes it a good constituent of the daily diet.
