Since ancient times, various herbal medicines have been used in folk medicine to treat a variety of diseases. While the majority of drugs belong to the Kingdom of Plantae, some drugs from the Kingdom of Animalia are listed in various Materia medica of alternative medicines. Animal-derived drugs are mentioned in the Unani system of Medicine (USM) and have been used successfully to treat a variety of diseases. Marjān (Corallium rubrum) is a vital marine drug of animal origin that has been used in USM since ancient times and continues to be used today. It possesses a variety of beneficial pharmacological properties, including tonic effects on the heart, brain, stomach, and eyes, pregnancy protection, expectorant, and hemostyptic properties. It is used to treat hemoptysis, palpitation, bleeding piles, hemiplegia, heart failure, and general weakness. It is also an ingredient in a variety of Unani formulations with pharmacological significance. Unani physicians expanded the uses of Marjan and successfully used it to treat a variety of new diseases. There is a dearth of scientific research on its pharmacological and medicinal properties. The urgent need is to validate the Unani claims about its beneficial cardiac and nervine actions, as well as other significant actions mentioned in the Unani literature.

Silymarin is a standardized extract obtained from the seeds and fruits of Silybum marianum L., or commonly called milk thistle, a member of Carduus marianum family that contains mix of flavonolignans. Some epidemiological and preclinical studies revealed that S. marianum L. has been used for herbal remedies for centuries for its pharmacological activity. In this review, pharmacological studies in vitro and in vivo of silymarin are discussed thoroughly stressing on antioxidant, antimicrobial, antiviral, and anti-carcinogenic aspects of silymarin. In addition, the protective influences of silymarin on some organs such as heart, liver, bone, and neuron tissue are reviewed as well. This review would be useful for further study regarding the potential of natural plant, notably silymarin, and its therapeutic potential in the prevention and treatment of diseases.

Through bio-guided isolation, two natural iron chelators were isolated from Mangifera indica L. leaves, identified as mangiferin (1) and iriflophenone-3-C-β-D-glucoside (2). Their iron-chelating activity was compared to that of Desferal® using bipyridyl assay and EDTA as a standard. Mangiferin showed the highest activity with IC50 value of 0.385 mM (162.85 μg/mL). Furthermore, two combinations of mangiferin with Desferal® (M-D) and iriflophenone-3-C-β-D-glucoside (M-I) were evaluated. The results showed that mangiferin potentiated the iron chelation activity of Desferal® about 46%, also that M-I combination is a promising candidate formula for iron chelation therapy. In addition, mangiferin and Desferal-iron complexes were prepared and characterized by IR, UV, and Mass spectra to compare their mode of chelation to iron. Their structural stability was studied by DFT calculations. Furthermore, they displayed increased ABTS antioxidant activity when bound to iron as compared to their free form, which enhances their pharmacological importance.

This study was designed to characterize the effect of ginsenoside-Rg2 (Rg2), one of panaxatriol saponins isolated from Korean ginseng root, on the release of catecholamines (CA) in the perfused model of the rat adrenal medulla, and also to establish its mechanism of action. Rg2 (3~30 μM), administered into an adrenal vein for 90 min, depressed acetylcholine (ACh)-induced CA secretion in a dose- and time-dependent manner. Rg2 also time-dependently inhibited the CA secretion induced by 3-(m-chloro-phenyl-carbamoyl-oxy)-2-butynyltrimethyl ammonium chloride (McN-A-343), 1.1-dimethyl-4-phenyl piperazinium iodide (DMPP), and angiotensin II (Ang II). Also, during perfusion of Rg2, the CA secretion induced by high K+, veratridine, cyclopiazonic acid, methyl-1,4-dihydro-2,6-dimethyl-3-nitro-4-(2-trifluoro-methyl-phenyl)-pyridine-5-carboxylate (Bay-K-8644) depressed, respectively. In the simultaneous presence of Rg2 and Nω-nitro-L-arginine methyl ester hydrochloride (L-NAME), the CA secretion induced by ACh, Ang II, Bay-K-8644 and veratridine was restored nearly to the extent of their corresponding control level, respectively, compared to those of inhibitory effects of Rg2-treatment alone. Virtually, NO release in adrenal medulla following perfusion of Rg2 was significantly enhanced in comparison to the corresponding spontaneous release. Also, in the coexistence of Rg2 and fimasartan, ACh-induced CA secretion was markedly diminished compared to the inhibitory effect of fimasartan-treated alone. Collectively, these results demonstrated that Rg2 suppressed the CA secretion induced by activation of cholinergic as well as angiotensinergic receptors from the perfused model of the rat adrenal gland. This Rg2-induced inhibitory effect seems to be exerted by reducing both influx of Na+ and Ca2+ through their ionic channels into the adrenomedullary cells as well as by suppressing Ca2+ release from the cytoplasmic calcium store, at least through the elevated NO release by activation of NO synthase, which is associated to the blockade of neuronal cholinergic and AT1-receptors. Based on these results, the ingestion of Rg2 may be helpful to alleviate or prevent the cardiovascular diseases, via reduction of CA release in adrenal medulla and consequent decreased CA level in circulation.

Type 2 diabetes mellitus (T2DM) and its complications are important noncommunicable diseases with high mortality rates. Protein tyrosine phosphatase 1B (PTP1B) and aldose reductase inhibitors are recently approached and advanced for T2DM and its complications therapy. Matricaria chamomilla L. is acknowledged as a worldwide medicinal herb that has many beneficial health effects as well as antidiabetic effects. Our research was designed to determine the most potential antidiabetic phytochemicals from M. chamomilla employing in silico study. 142 phytochemicals were obtained from the databases. The first screening employed iGEMdock and Swiss ADME, involving 93 phytochemicals. Finally, 30 best phytochemicals were docked. Molecular docking and visualization analysis were performed using Avogadro, AutoDock 4.2., and Biovia Discovery Studio 2016. Molecular docking results demonstrate that ligand-protein interaction's binding affinities were -5.16 to -7.54 kcal/mol and -5.30 to -12.10 kcal/mol for PTP1B and aldose reductase protein targets respectively. In silico results demonstrate that M. chamomilla has potential antidiabetic phytochemical compounds for T2DM and its complications. We recommended anthecotulide, quercetin, chlorogenic acid, luteolin, and catechin as antidiabetic agents due to their binding affinities against both PTP1B and aldose reductase protein. Those phytochemicals' significant efficacy and potential as antidiabetic must be investigated in further advanced research.

Lentinus edodes contains functional metabolites such as polysaccharopeptides, lectins, and secondary metabolites. Fermented soybean paste is representative fermented materials in Korea, and is gradually increasing due to various biological activities. In the present study, ethanol extracts of fermented products with/without L. edodes were designated as SPL and SP, and prepared to develop safer and therapeutic functional foods with antioxidant and anti-inflammatory activities for treatment of inflammatory disorders. SP and SPL extracts exhibited antioxidant effects via inhibiting radical activities. Inflammatory mediators, nitric oxide (NO), prostaglandin E2 (PGE2), interleukin (IL)-1β, IL-6, IL-8, tumor necrosis factor (TNF)-α, and inducible nitric oxide synthase (iNOS) production and nuclear factor-kappa B (NF-κB) activation were down-regulated by two extracts. SPL extract more strongly enhanced the antioxidant and anti-inflammatory activities than SP extract. Its' activities shown more longer fermentation period and more strong inhibitory effects. Taken together, our results suggested that fermented product with medicinal plant has synergic effect and SPL can be a potential candidate for treatment of inflammatory bowel diseases.

The Coumarin (1,2-benzopyrone) is the main secondary metabolite of Mikania laevigata Sch. Beep ex Baker and Mikania glomerata Spreng., which are popularly known as guaco. These plants have been used mainly in traditional medicine in the treatment of respiratory diseases because their bronchodilator effect. However, there are around 200 species of Mikania, which are quite similar in appearance. From these, only M. leavigata and M. glomerata have high concentrations of coumarins. In this line, the falsification of products Mikania based has been frequent. In this sense, this work demonstrated the application of the easy, fast, e not destructive method based in Nuclear Magnetic Resonance in quantitative mode (qNMR) for the determination of coumarin in both commercial and homemade guaco products. Thus, in the first step the compounds were extract from guaco leaves and syrups using chloroform (CHCl3), with or without ultrasound. About the method, was linear with a R2= 0.9947 for 1,2-benzopyrone, with detection and quantification limits with were 0.11 and 0.36 mg mL-1 respectively. In the same line, the method was safe with RSD <0.3% and with recovery ranging from 93-101%. To confirm the applicability of the method, in the last step was applied to 10 real samples (6 from leaves and 4 from syrups). The content of the coumarin in the leaf extract ranged from 0.62 to 1.30 mg mL-1. For syrups I, II and IV, the content of coumarin was in accordance with the manufacturers. However, for de Syrup III, the concentration was 155% higher. In summary, the qNMR is a rapid method with minimal sample preparation that can be used to quantify coumarin in home-made plant extracts as well as in commercial samples as syrup for instance. This method is applicable for quality control of different plants-based products.
