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.

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.

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.

Abstract Objectives Cocoa beans undergo fermentation, roasting, and possibly alkalization prior to consumption. Cocoa and chocolate have been shown to exert anti-inflammatory effects. Previous studies have shown that roasting and alkalization can adversely affect the total phenolic content (TPC) of cocoa, but the effect of these steps on bioactivity has not been well-studied. Our objective was to prepare cocoa powders using different roasting and alkalization protocols and measure their chemical composition and in vitro anti-inflammatory activity. Methods Cocoa beans were roasted (110–150°C) and alkali-treated (0 – 120 min) using a 22 + center point study design. Cocoa nibs were defatted and extracted with 70% aqueous acetone. The extract was dried prior to analysis. TPC was determined using the Folin-Ciocalteu method. Select polyphenols were quantified by liquid chromatography. In vitro anti-inflammatory activity was assessed as inhibition of phospholipase A2 (PLA2) and inhibition of interleukin 8 (IL8) production by tumor necrosis factor a-stimulated HT-29 human colon cells. Results Roasting and alkalization led to decreased TPC, but alkalization had a greater effect. Cocoa beans roasted at 130°C and alkalized for 120 min had 44% lower TPC than those roasted that same way but without alkalization. In the absence of alkalization, beans roasted at 150°C had only a 13% lower TPC than beans roasted at 110°C. Roasting and alkalization also influenced the levels of individual polyphenols, but the effects varied based on the analyte of interest. Roasting tended to enhance the PLA2, inhibitory potency of the cocoa whereas alkalization reduced inhibitory potency. Cocoa that had been roasted at 150°C but not alkalized had the lowest IC50 (14 mg/mL) whereas cocoa that had been roasted at 150°C and alkalized for 120 min had the highest (&gt;100 mg/mL). Similar results were observed for inhibition of IL8 production. Conclusions Roasting and alkalization are important for achieving desired sensory characteristics in cocoa, but these processes adversely affect the levels of polyphenols in cocoa and has been considered inconsistent with maintaining bioactivity. Our results suggest that it is possible to identify processing protocols that balance the sensory characteristics of cocoa with its anti-inflammatory activity.

Fruit juices are considered as an important source of phenolic compounds. Black mulberry, pomegranate and orange juices were selected to assess their anti-inflammatory activity. Total phenolic content was determined using Folin-Ciocalteu colorimetric method. The anti-inflammatory activity was evaluated using RBC membrane stabilization method. Ibuprofen was used as a standard drug. Total phenolic content of black mulberry juice, pomegranate juice and orange juice was 3.02 gGAE/l, 1.83 gGAE/l and 0.76 gGAE/l and the percentage inhibition of RBC haemolysis varied between (27.41-43.19%), (24.06-39.06%) and (10.12-22.54%), respectively. Black mulberry juice revealed the highest anti-inflammatory activity among the studied juices. This finding might be attributed to the high phenolic content of this juice compared to others.

Antioxidant fractions from Ophioglossum thermale were extracted with five different polar solvents using a Soxhlet type extractor. The total phenolic content of the extracts was determined by the Folin-Ciocalteu method. The ethyl acetate fraction of O. thermale was found to contain maximum phenolics. The dried fractions were screened for their antioxidant activity potential using in vitro model systems such as 1,1-diphenyl-2-picryl hydrazyl (DPPH), nitroblue tetrazolium (NBT) and lipid-peroxidation reduction at different concentrations. Results revealed that the EtOAc fraction exhibited the best performance in the DPPH assay, NBT assay and lipid peroxidation. All fractions showed more potent antioxidant capacity than green tea extract, a well-known antioxidant. Furthermore, the EtOAc fraction has the highest total phenolic content (475.65 mg of EGCG/g). In addition, the EtOAc fraction at 0.005% and 0.01% (g/100 ml) also significantly inhibited UVB irradiation-induced ROS generation in human dermal fibroblasts (HDFs). In a carrageenan-induced edema model, the EtOAc fraction showed an inhibitory effect (21.5%, p < 0.05) at 200 mg/kg (p.o.) after 300 min administration. Consequently, 3-O-methylquercetin (3MQ) was also isolated from the antioxidative EtOAc fraction. The data obtained using the above in vitro and in vivo tests suggest that the antioxidant activity of O. thermale and its anti-inflammatory effect on carrageenan-induced acute inflammation can be attributed to its ameliorating effect on oxidative damage, and thus it has great potential as a source for natural health products. To the best of our knowledge, this is the first report on the antioxidant activity of different polar extracts from O. thermale.

A sea fennel (Crithmum maritimum) aqueous extract was prepared and loaded into soybean phosphatidylcholine liposomes. Both the free extract (FE), and the empty (L) and loaded (L-FE) liposomes were shown to be non-cytotoxic to THP-1 and Caco-2 cells. The anti-inflammatory effect was tested on THP-1 cells differentiated into macrophages. FE showed anti-inflammatory activity, revealed by the induced secretion of IL-10 cytokines in macrophages that were subsequently stimulated with LPS. Also, a decrease in TNF-α production by L was observed, evidencing that liposomes reduced the pro-inflammatory mediators’ secretion. The liposomes (L) showed protective anti-inflammatory activity and also were able to downregulate the inflammation. Furthermore, L-FE were also found to downregulate the inflammation response, as they were able to decrease TNF-α secretion in macrophages previously exposed to LPS. The simulated in vitro gastrointestinal digestion (GID) of FE diminished the chlorogenic acid content (the main polyphenolic compound of the extract) by 40%, while in L-FE, the amount of this phenolic compound increased with respect to the undigested liposomes. The amount of bioaccessible chlorogenic, however, was similar for FE and L-FE. The percentage of chlorogenic acid absorbed through a Caco-2 cell monolayer after 3 h of incubation, was significantly similar for the extract and the liposomes (~1.5%), without finding significant differences once the extract and liposomes were digested.
