15–Lipoxygenase inhibition of Commelina benghalensis, Tradescantia fluminensis, Tradescantia zebrina

Abstract

T. fluminensis is a potentially good source of 15-lipoxygenase inhibitors.

Antioxidative and anti‐inflammatory potential of phenolics from purple basil (Ocimum basilicum L.) leaves induced by jasmonic, arachidonic and β‐aminobutyric acid elicitation

“…As previous research reported, (McCue & Shetty, ) RA, in addition to the antioxidant properties, may also determine other biological activities, such as anti‐inflammatory or anticancer properties. Several works have been done to look for new anti‐inflammatory compounds from natural sources (Gawlik‐Dziki, ; Sekhar et al ., ; Alaba & Chichioco‐Hernandez, ), but a limited number of studies regards the influence of plant elicitation on the ability to inhibit the activity of enzymes involved in inflammation. In this study, the capacity of phenolic‐rich fraction obtained from the elicited basil leaves to inhibit the activity of two enzymes of inflammatory process (LOX and COX) was studied.…”

Antioxidant Content, Antioxidant Activity, and Antibacterial Activity of Five Plants from the Commelinaceae Family

“…It has oval, pointed leaves, variegated green and silver stripes on the upper surface, with a purple underside [ 20 , 21 ]. T. zebrina is traditionally used to treat gastrointestinal disorders [ 22 ].Other studies have also reported that T. zebrina exhibits insecticidal properties [ 23 ] and can inhibit the 15-lipoxygenase pathway involved in asthmatic attacks [ 24 ].…”

Cherry stem phenolic compounds: Optimization of extraction conditions and in vitro evaluations of antioxidant, antimicrobial, antidiabetic, anti‐inflammatory, and cytotoxic activities

“…Lipoxygenase and xanthine oxidase are important enzymes that play a role in many inflammatory diseases (Alaba & Chichioco‐Hernandez, 2014; Nessa et al., 2010). According to our knowledge, this is the first study about the inhibitory effect of the cherry stem extract against lipoxygenase and xanthine oxidase enzyme.…”

“…The lipoxygenase inhibitory capacity of the concentrated cherry stem extract was analyzed according to the method provided by Alaba and Chichioco‐Hernandez (2014). After preincubation of 15‐lipoxygenase solution (8,460 U/ml in 0.1 M phosphate buffer pH 8) (50 μl) and phosphate buffer (2,740 μl) with different concentrations (0–8 mg/ml) of the extract (10 μl) for 5 min at 30°C, 200 μl of linoleic acid (1,980 μmol/L) was added to start the reaction and it was continued for 5 min at room temperature and monitored with 30 s interval at 234 nm.…”

“…Furthermore, they have many biological activities including antiallergen, antimutagenic, anticarcinogen, antiglycemic, anticholesterol, anti‐inflammatory, antimicrobial, and tranquilizing properties that could be used in cosmetic, drug, and food industries (Shahidi & Ambigaipalan, 2015). Therefore, the number of researches investing the biological effects of the plants have been increased for the last years (Ademović et al, 2017; Aires, Dias, Carvalho, & Saavedra, 2017; Ajiboye et al., 2018; Alaba & Chichioco‐Hernandez, 2014; Daniela et al, 2007; Demir, Akpınar, Kara, & Güngör, 2019; Nessa, Ismail, & Mohamed, 2010; Oboh, Akinyemi, & Ademiluyi, 2012; Oboh, Ogunsuyi, Ogunbadejo, & Adefegha, 2016; Pulbutr et al., 2017; Sarikurkcu, Eskici, Karanfil, & Tepe, 2019; Shobana, Sreerama, & Malleshi, 2009; Zhishen, Mengcheng, & Jianming, 1999).…”
