The Relationship

There is little research on how cooking and digestion affect the anti-inflammatory activity of culinary herbs. Thus, the aim of this paper was to investigate this activity following cooking andin vitrodigestion of the common culinary herbs, rosemary, sage, and thyme, and the relationship between their anti-inflammatory activity, polyphenol content, and antioxidant capacity. The anti-inflammatory activity of uncooked (U), cooked (C), cooked andin vitrodigested (C&D), and standardised (STD, 30 mg/mL) culinary herbs was assessed by measuring their effect on interleukin 8 (IL-8) release from stimulated human peripheral blood lymphocytes (PBLs) and Caco-2 cells. The trolox equivalent capacity (TEAC) and estimated total phenolic content of the herbs were also determined. There was a significant decrease in IL-8 release from PBLs stimulated with H2O2incubated with (U), (C), (C&D), and (STD) herbs and from Caco-2 cells stimulated with TNFαincubated with (C&D) and (STD) herbs. PBLs pre-incubated with (C&D) herbs prior to stimulation (H2O2or TNFα) caused a significant inhibition in IL-8 release. The significant correlations between TEAC and estimated phenolic content and the anti-inflammatory activity suggest a possible contributory role of polyphenols to the anti-inflammatory activity of the culinary herbs investigated.

Epidendrum coryophorum belongs to the Orchidaceae family. Traditional uses of some species for this genus include infusions of the leaves used for kidney problems, treat influenza, conjunctivitis, liver pain, relieve kidney symptoms, and hypoglycemic effect. This work's objective was to determine the phytochemical profile of the ethanolic extract of Epidendrum coryophorum leaves and to evaluate the potential anti-inflammatory activity in vitro of the extract employing the erythrocyte membrane stabilization method. The phytochemical screening carried out in this work suggested phenols, coumarins, flavonoids, tannins, steroids, and sterols in the ethanolic extract of Epidendrum coryophorum leaves. Cardiotonic glycosides and carbohydrates were also found. The ethanolic extract's UV-Vis spectrum showed absorption maxima at 268 nm and 332 nm, which could correspond to flavonoids of the flavonoid classes, 3-OH substituted flavonols, or isoflavones. The quantitative determination of total phenols of the ethanolic extract was carried out using the Folin-Ciocalteu method. The total phenolic content expressed as mg Gallic acid equivalent (G.A.E.) per gram of extract was found to be 19,96 mgGAE/g of Epidendrum coryophorum. The ethanolic extract of Epidendrum coryophorum leaves showed hemolysis inhibition values ​​of 18,19% at 1,0 mg/mL, 38,98% at 1,5 mg/mL and 40,94% at 2,5 mg/mL compared with aspirin (positive control) giving values ​​of 65,33% at 1,0 mg/mL, 72,26% at 1,5 mg/mL and 73,75% at 2,5 mg/mL. The values ​​obtained for inhibition of hemolysis with ethanolic extract, compared with the values ​​obtained with a pure anti-inflammatory, are significant and demonstrate anti-inflammatory activity in Epidendrum coryophorum. Keywords: Epidendrum coryophorum, total phenolic content, microencapsulation, anti-inflammatory activity

Sorghum biscuits were enriched with mushroom powders (Lentinula edodes, Auricularia auricula and Tremella fuciformis) at 5%, 10% and 15% substitution levels. An in vitro gastrointestinal digestion was used to evaluate the effect of this enrichment on the phenolic content and soluble peptide content as well as antioxidant activities of the gastric or intestinal supernatants (bio-accessible fractions), and the remaining portions of phenolic compounds, antioxidants and β-glucan in the undigested residue (non-digestible fraction). The phenolic content of the gastric and intestinal supernatants obtained from digested mushroom-enriched biscuits was found to be higher than that of control biscuit, and the phenolic content was positively correlated to the antioxidant activities in each fraction (p < 0.001). L. edodes and T. fuciformis enrichment increased the soluble protein content (small peptide) of sorghum biscuits after in vitro digestion. All mushroom enrichment increased the total phenolic content and β-glucan content of the undigested residue and they were positively correlated (p < 0.001). The insoluble dietary fibre of biscuits was positively correlated with β-glucan content (p < 0.001) of undigested residue. These findings suggested that enriching food with mushroom derived dietary fibre increases the bioavailability of the non-digestible β-glucan and phenolic compounds.

Physalis peruviana calyces are used extensively in folk medicine. The crude ethanolic extract and some fractions of calyces were evaluated in order to explore antioxidant and anti-inflammatory activities. The anti-inflammatory activity was evaluated by the TPA-induced ear edema model. The antioxidant in vitro activity was measured by means of the superoxide and nitric oxide scavenging activity of the extracts and fractions. The butanolic fraction was found to be promising due to its anti-inflammatory and antioxidant activities. Therefore, a bio-assay guided approach was employed to isolate and identify rutin (1) and nicotoflorin (2) from their NMR spectroscopic and MS data. The identification of rutin in calyces of P. peruviana supports the possible use of this waste material for phytotherapeutic, nutraceutical and cosmetic preparations.

Змееголовник молдавский (Dracocephalum moldavica L.) в народной медицине используется в качестве противовоспалительного, ранозаживляющего, отхаркивающего и седативного средства. В ФГБНУ ВИЛАР разработан змееголовника молдавского травы экстракт сухой под условным названием «Люкатил» (сумма фенольных соединений 64,12% в пересчёте на цинарозид). Цель работы - изучение острой токсичности и противовоспалительной активности экстракта змееголовника для разработки на его основе лекарственного препарата. Методика. Проведено определение параметров острой токсичности и противовоспалительной активности экстракта. При изучении острой токсичности экстракта по методу Кербера использованы белые нелинейные мыши-самцы в количестве 30 особей. «Люкатил» вводили животным внутрижелудочно в дозах 500, 1000, 1500 и 2000 мг/кг. Для выявления противовоспалительной активности экстракта змееголовника молдавского использована in vitro ферментная биотест-система на основе индуцибельной NO-синтазы. Для выявления противовоспалительной активности экстракта in vivo использованы нелинейные мыши-самцы. Оценку влияния экстракта в дозе 200 мг/кг на экссудативную стадию воспаления проводили на модели 1% формалинового отёка. В качества препарата сравнения использовали индометацин (5 мг/кг). Формалиновый отёк вызывали однократным субплантарным введением под апоневроз задней правой лапки мыши 0,05 мл 1% формалина в качестве флогогенного агента. Величину отёка определяли по разнице в массе лапок контрольных и опытных животных и рассчитывали процент снижения степени отёка. Результаты. При однократном введении экстракт «Люкатил» не приводил к гибели животных, изменения внешнего вида и поведенческих реакций мышей не наблюдалось. В соответствии с классификацией токсичности химических веществ по ГОСТ 12.1.007-76 «Люкатил» является малотоксичным веществом. In vitro установлена высокая противовоспалительная активность экстракта, при этом остаточная активность iNOS снижалась до 25%. Экстракт в дозе 200 мг/кг in vivo обладал статистически значимым противовоспалительным эффектом. Он подавлял развитие экссудативной фазы воспаления на 33,7%, по сравнению с контрольной группой животных, уступая противовоспалительному эффекту индометацина. Заключение. Змееголовника молдавского травы экстракт сухой под условным названием «Люкатил» является малотоксичным веществом, обладает выраженным противовоспалительным эффектом в опытах in vitro, in vivo и является перспективным объектом для дальнейшего фармакологического изучения в качестве противовоспалительного лекарственного средства.Moldavian dragonhead (Dracocephalum moldavica L.) is used in traditional medicine as an anti-inflammatory, wound-healing, expectorant, and sedative means. In our Institute, a Moldavian dragonhead herb dry extract (total phenolic content, 64.12% in cynaroside equivalent) was developed and conventionally named Lyukatil. Objective. To study acute toxicity and anti-inflammatory activity of the dragonhead extract for developing a drug based on this extract. Method. Parameters of acute toxicity and anti-inflammatory activity of the extract were assessed. The study of acute toxicity of the extract was performed using the Kerber method on male white mongrel mice (n=30). Lyukatil was administered to the animals intragastrically at doses of 500 mg/kg, 1000 mg/kg, 1500 mg/kg, and 2000 mg/kg. Anti-inflammatory activity of the Moldavian dragonhead extract was determined in vitro using an enzyme Biotest system based on inducible NO synthase. Mongrel male mice were used to study the anti-inflammatory activity of the extract in vivo. The effect of the extract at a dose of 200 mg/kg on the exudative phase of inflammation was evaluated on a model of 1% formalin-induced edema. Indomethacin 5 mg/kg was used as a reference drug. Formalin edema was induced by a single subplantar injection of 0.05 ml of 1% formalin as a phlogogenic agent under the aponeurosis of the right hind leg. The degree of edema was determined by the difference in leg weights in control and experimental animals; then the decrease in edema was calculated in per cent. Results. A single administration of the extract Lyukatil did not cause death of animals, changes in the appearance or in behavioral responses, shortness of breath, or drowsiness. In accordance with the toxicity classification for chemical substances as per GOST Standard 12.1.007-76, Lyukatil is a low-toxic substance. The extract at a dose of 200 mg/kg exerted a significant anti-inflammatory effect as shown by suppression of the exudative phase of formalin-induced inflammation by 33.7% compared to the control group. However, this effect was inferior to the anti-inflammatory effect of indomethacin. Conclusions. The Moldavian dragonhead herb dry extract under the conventional name of Lyukatil is a low-toxic substance that has a significant anti-inflammatory effect both in vitro and in vivo and is a promising target for further pharmacological studies as an anti-inflammatory drug.

<p><strong>Objective: </strong>To evaluate the potential antioxidant, anti-inflammatory and antibacterial activities of aqueous and methanolic extracts of leaves of <em>Leucas aspera</em> (Thumbae).</p><p><strong>Methods: </strong>Phytochemical screening of the leaves of <em>L. aspera</em> was followed by analysis of antioxidant activity by means of DPPH (2, 2-diphenyl-1-picrylhydrazyl) radical scavenging activity. <em>In vitro</em> anti‐inflammatory activity was evaluated using lipoxygenase inhibition, albumin denaturation assay, membrane stabilization assay and proteinase inhibitory activity at different concentrations. Aspirin was used as a standard drug for the study of anti‐inflammatory activity. Linear regression analysis was used to calculate half maximal inhibitory concentration, IC50 value. The zone of inhibition was performed against common pathogens to determine the antimicrobial activity at different concentrations of plant extracts (60%, 70%, 80%).</p><p><strong>Results: </strong>The phytochemical analysis revealed the presence of carbohydrates, amino acid, alkaloids, tannins, flavonoids, glycosides, xanthoproteins, and phenols. The total phenolic and flavonoid content was found to be 2.25±0.04 mg GAE/g (gallic acid equivalents) and 1.2±0.05 mg QE/g (Quercetin equivalents) of fresh weight tissue respectively. The IC50 values for hydrogen peroxide scavenging activity were found to be 244.6 µg/ml. The extract inhibited the lipoxygenase enzyme activity with an IC50 value of 356.3 µg/ml. Maximum inhibition of heat-induced protein denaturation of 69% was observed at 400 μg/ml, IC50 249.6 μg/ml. Proteinase activity was also significantly inhibited (IC50 = 421.6 μg/ml). Membrane stabilization assay attributed minor protection by the leaf extract with an IC50 of 206.7. It was observed that <em>E. coli</em> were inhibited at all concentrations, followed by <em>Klebsiella</em> and <em>Pseudomonas</em>.</p><p><strong>Conclusion: </strong>Results indicate that L. aspera possess anti-inflammatory properties due to the strong occurrence of polyphenolic compounds such as alkaloids, flavonoids, tannins and steroids that serve as free radical inhibitors or scavenger. Compounds of the plant L. aspera may hence be used as lead compounds for designing potent anti-inflammatory drug which can be used for treatment of various diseases.</p><p> </p>
