Essential oil content of and phenolic compounds flower-fruit, root, and aerial parts of Heracleum pastinacifolium subsp. incanum were analysed by GC/MS and LC/MS methods, respectively. Antidiabetic, anticholinesterase, and antioxidant activities of flower-fruit, root, aerial parts methanol extracts were evaluated. Apiole (35.0%), myristicine (72.2%), and myristicine (15.1%) were found as major compounds of fruit-flower mixture, root, aerial part essential oils, respectively. Hesperidin was found the highest amount in aerial part and flower-fruit extracts with 8904.2621 ng/mL and 11558.3634 ng/mL values, respectively. Fruit-flower extract showed the highest activity against α-glucosidase (24%). Root extract demonstrating the highest activity (18%) against AChE enzyme. Flowers-fruits mixture methanol extract had a higher % inhibition value on ABTS·+ and DPPH•. Flowers-fruits mixture methanol extract was rich in total phenol, total tannin, and protein content. All the extracts were determined as genetoxically safe according to the results of Ames/Salmonella, Escherichia coli WP2 and Allium cepa assays.

Background/aims: Sepsis is one of the major problems encountered in intensive care units, causing organ damage and increasing mortality. Suberosin (SBR) is a type of coumarin with antioxidant and anti-inflammatory activities. The goal of this study is to explore the protective effects of SBR on the lungs in a rat model of sepsis. Methods: Male Wistar rats were utilized in this study. A cecal ligation and puncture (CLP) model was applied to induce sepsis. Rats were separated into six groups with nine animals in each group, including healthy control, SBR, CLP, and CLP + SBR (5, 10, and 20 mg/kg) groups. Superoxide dismutase (SOD), glutathione (GSH) enzyme activities, and malondialdehyde (MDA) level were measured via enzyme-linked immunosorbent assay (ELISA). The messenger RNA (mRNA) expressions of tumor necrosis factor α (TNF-α) and interleukin 1β (IL-1β) were evaluated by real-time polymerase chain reaction (RT-PCR). Histopathological changes in the lungs were investigated with hematoxylin and eosin (H&E). Results: MDA levels and GSH and SOD enzyme activities were negatively affected in the CLP group, but SBR treatment ameliorated these oxidative stress parameters in the SBR1-3 groups (p< 0.05). The mRNA expressions of TNF-α and IL-1β were increased in the CLP group, and SBR treatment decreased those expression levels in a dose-dependent manner (p < 0.05). Organ damage and necrosis were seen in the CLP group and were alleviated in the SBR3 group. Immunohistochemical (IHC) analysis of lung tissues demonstrated decreased TNF-α and IL-1β immunopositivity in the SBR1-3 groups (p< 0.05). Conclusions: SBR ameliorated sepsis-related lung injury in a dose-dependent manner. This compound has significant potential as a future agent in the treatment of sepsis.

L929 hücre hattında oluşturulan lipopolisakkarit (LPS) kaynaklı sitotoksisite modelinde Ferulago pauciradiata (Apiaceae) bitkisinin kök kısmından izole edilen prantşimgin (Prn) bileşiğinin etkisinin incelenmesi. L929 hücre hatları, 37°C'de %5 CO2'li inkübatörde standart hücre kültürü prosedürleri kullanılarak son konsantrasyonu 2 µL olacak şekilde Prn saf maddesi ve 1 saat sonra son konsantrasyonu 1 µL olacak şekilde LPS uygulandı. LPS uygulamasının ardından, gerekli olan 24, 48 ve 72 saat inkübasyon süreleri sonunda sitotoksik etkilerin belirlenmesi amacıyla kolorimetrik bir metot olan MTT protokolü uygulandı. IC50 değerleri, Prn için 0.28 µg/mL ve LPS için ise 1 µg/mL olarak hesaplandı. L929 hücre hatlarına LPS uygulanmasının zamana bağlı olarak hücresel indekste anlamlı derecede azalmaya neden olmuştur. Ayrıca Prn+LPS gruplarında ise sadece LPS uygulanan grubuna göre azalmış hücre indeksini, anlamlı derecede artırdığı hatta kontrole yaklaştırdığı tespit edilmiştir.L929 hücre hattına uygulana LPS ile oluşturulan sitotoksisite ve hücre hasarını Pnr uygulaması sonucunda düzeldiği tespit edildi.
