Evaluation of anti-fungal activity derivative from Premna odorata Blanco extract by deep eutectic solvents
Fungal organisms are an opportunistic pathogen commonly found in different parts in human body like oral cavity and vagina. Recent study has revealed a critical need for novel antifungal medicines developed from medicinal plant extracts due to concerns about fungal pathogen resistance to commercial medication. In the present work, Premna odorata Blanco, belonging to the family Lamiaceae was evaluated in vitro antifungal activity against two fungal organism isolated from clinical cases. With the aim to replace toxic conventional solvents through deep eutectic solvents was used and phytochemical compounds were determined (total phenol content, total flavonoid content). ChMa extracts of Premna odorata Blanco demonstrate a significant antifungal activity against Candida albicans, Monilinia spp. Higher than water extract. While the DES2 extract reported the highest phenolic contents (3.58 mg GAE/100 g DW) and total flavonoid content (0.028 mg RE/100 g DW) compared with water extract. In conclusion, the study suggests that the Premna odorata Blanco extracts by deep eutectic solvents are promising for the development of treatments against various fungal diseases with a friendly green procedure, low toxicity and new application in pharmaceutical industry
Deep Eutectic Solvents (DESs) as Green Extraction Media of Beneficial Bioactive Phytochemicals
Deep eutectic solvents (DES) are a mixture of two or more components and are classified as ionic solvents with special properties such as low volatility, high solubility, low melting points, low-cost materials and are less toxic to humans. Using DES has been suggested as an eco-friendly, green method for extraction of bioactive compounds from medicinal plants and are a safe alternative for nutritional, pharmaceutical and various sector applications. Conventional solvent extraction methods present drawbacks such as long extraction period, safety issues, harmful to the environment, costly and large volume of solvents required. The extraction method with DES leads to higher extraction yield and better bioactivity results as compared to the conventional solvents. This review provides a summary of research progress regarding the advantages of using DES to extract bioactive compounds such as phenolic acid, flavonoids, isoflavones, catechins, polysaccharides, curcuminoids, proanthocyanidin, phycocyanin, gingerols, ginsenosides, anthocyanin, xanthone, volatile monoterpenes, tannins, lignin, pectin, rutin, tert-butyl hydroquinone, chlorogenic acids, resveratrol and others, as opposed to using conventional solvents. The bioactivity of the extracts is determined using antioxidant, antibacterial and antitumor activities. Hence, DESs are considered potential green media with selective and efficient properties for extracting bioactive ingredients from medicinal plants
Ethnomedicinal Plants from Iraq as Therapeutic Agents against Mycobacterium tuberculosis: A Review
Mycobacterium tuberculosis is a highly infectious pathogen, which can affect both humans and animals. The metabolic products of this bacterium affect the pulmonary, nervous, lymphatic, and cardiovascular systems. The aim of this review is to provide information on certain local herbs from Iraq, which have been found to be effective against Mycobacterium tuberculosis. In this report, we have reviewed 13 medicinal plants and their anti-mycobacterial activities. The family, traditional medicinal uses, common local names, in vitro activity of the crude extract, and information about bioactive chemical composition of these plant species have been described. The crude extracts of these medicinal plants can be used to develop novel drugs against tuberculosis
Antimycobacterial Activity of <i>Rosmarinus officinalis</i> (Rosemary) Extracted by Deep Eutectic Solvents
Tuberculosis (TB) is a massive problem for public health and is the leading cause of illness and death worldwide. Rosemary (Rosmarinus officinalis) is used traditionally to treat many diseases, such as infections of the lungs including pulmonary TB. R. officinalis was collected from Al Anbar Governorate, Iraq, and was extracted with deep eutectic solvents (DESs) of many different kinds and with conventional water solvent. The antimycobacterial activities of the R. officinalis extracts were tested against multidrug-resistant (MDR) Mycobacterium tuberculosis by agar disc diffusion assay. Minimum inhibitory concentrations were measured spectrophotometrically at 570 nm. Then, a time-kill assay and cell membrane integrity analysis were conducted to investigate the effects of the most active extracts on cell growth. The in vitro cytotoxicity of the most active extracts was evaluated against Rat Embryonic Fibroblasts (REF) cell line by MTT assay. Liquid chromatography-mass spectrometry (LC-MS) was conducted to analyze the chemical components of the most active extracts. At 200 mg/mL concentration, a significant inhibition activity was seen in DES2: Tailor (DIZ = 17.33 ± 1.15 mm), followed by DES3: ChGl, DES1: LGH and DES4: ChXl. The best result was DES2: Tailor, which had a MIC of 3.12 mg/mL and an MBC of 12.5 mg/mL. The DES2 extract exhibited a high drop in the number of colonies over time, killing more than 80 colonies. The main phytochemical compounds of the R. officinalis extract were camphene, camphenilol, α-pinene, limonene, apigenin, camphor, carnosol, linalool and myrcene. R. officinalis extracts obtained by DESs have shown evident power in treating tuberculosis, and extraction by DES is a greener procedure than the methods involving conventional extraction solvents. As a result, additional research into the application of DES should be considered
