In this work phytochemical characterization of two medicinal plants from Lamiaceae family, Mentha rotundifolia and Satureja calamintha, has been carried out. Extracts obtained with different solvents were screened for different plant secondary metabolites and were biologically characterized by defining their antiradical and antibacterial activities. Phytochemical screening of M. rotundifolia and S. calamintha confirmed their richness in different secondary metabolites. The determination of phenolic compounds revealed high polyphenols contents in water: methanol (30:70) extracts with concentrations of 20.64?1.74 mg EAG/g DW and 13.45?0.91 mg EAG/g DW for M. rotundifolia and S. calamintha, respectively. These extracts were also characterized by high concentrations of flavonoids (Mentha rotundifolia 12.33?1.58 mg EQ/g DW, Satureja calamintha 7.11?0.02 mg EQ/g DW). Furthermore, the water: methanol (30:70) extract of M. rotundifolia was the most effective in inhibiting free radicals. Recorded inhibition diameters for both plant samples and tested microbial strains ranged from 6.66 mm to 13.66 mm. Presented results confirmed that tested indigenous Algerian plants are favorable sources of polyphenols with antioxidant and antimicrobial properties.

Background: The use of essential oils is receiving increasing attention worldwide, as these oils are good sources of several bioactive compounds. Nowadays essential oils are preferred over synthetic preservatives thanks to their antioxidant and antimicrobial properties. Several studies highlight the beneficial effect of essential oils extracted from medicinal plants to cure human diseases such as hypertension, diabetes, or obesity. However, to preserve their bioactivity, the use of appropriate extraction technologies is required. Method: The present review aims to describe the studies published so far on the essential oils focusing on their sources and chemical composition, the technologies used for their recovery and their application as antioxidants in food products. Results: The review has been structured in three parts. In the first part, the main compounds present in essential oils extracted from medicinal plants have been listed and described. In the second part, the most important technologies used for extraction and distillation, have been presented. In detail, conventional methods have been described and compared with innovative and green technologies. Finally, in the last part, the studies related to the application of essential oils as antioxidants in food products have been reviewed and the main findings discussed in detail. Conclusions: In summary, an overview of the aforementioned subjects is presented by discussing the results of the most recent published studies.

This study aims to evaluate the efficacy of two methods (agitation and ultra-sound) for extracting phenolic compounds from 15 native plants. Plant species collected in the Dehesa of Extremadura were used. The antioxidant, antihypertensive and antimicrobial activity of the phenolic extracts was investigated. Significantly different results were obtained when comparing the two extraction methods, with the highest concentrations of phenolic compounds found for ultrasound extraction. In addition, the extracts obtained for Cistus albidus, Cistus salviifolius, Rubus ulmifolius and Quercus ilex showed the highest concentrations of phenolic compounds. The antioxidant activity was higher in the extracts of Cistus and Q. ilex obtained by ultrasound, as was the antihypertensive activity. Antimicrobial activity was also higher in the extracts obtained by ultrasound from C. salviifolius and Q. ilex plants against bacteria and from Cistus ladanifer against yeasts. Therefore, it can be concluded that, with the ultrasound extraction of phenolic compounds from C. ladanifer, C. albidus and Q. ilex plants, it is possible to obtain extracts with important functional properties, so they could be studied for their use in food with the aim of obtaining healthy and safe products, favouring the sustainability of the environment of the Dehesa Extremeña.

Essential oils constitute a heterogeneous collection of chemical compounds. Their main characteristics are that they all synthesized by plants and are volatile and mostly soluble in ethanol. They have traditionally been obtained from plants and they have been widely used for insecticidal, medicinal and cosmetic purposes. Essential oils contains about 20–60 components at quite different concentrations and they are characterized by two or three major components at fairly high concentrations. Lately, the essential oils and various extracts of plants have gained special interest as sources of natural antimicrobial and antioxidant agents because of the resistance to antibiotics that some microorganisms have acquired and the possible toxicities of the synthetic antioxidants. Spices consumed daily in different types of food to improve flavors, since ancient times, are well known for their antioxidant and antimicrobial properties. During recent decades, numerous numbers of plants have been monitored for their possible role as repellents and insecticides. In this review, the chemical composition profile of some important medicinal plants was evaluated, then antimicrobial properties of a number of essential oils was compared. Antioxidant activity of some essential oils was also considered. Finally, essential oil repellent properties an an important characteristics was evaluated. Further investigation for available data related to the other biological properties of medicinal plants essential oil is recommended.DOI: http://dx.doi.org/10.3126/ijls.v9i2.12043 International Journal of Life Sciences 9 (2) : 2015; 9-13

The medicinal plants (Artemisia herba-alba) were subjected to mineral analysis, total protein and the phenolic contents. Couple plants were collected from AL-Gabal AL-Akhder region in Northeast of Libya (Coastal and Desert) Artemisia herba-alba 1 Artemisia herba-alba 2 respectively during November (2018).  Results showed that mineral content found to vary significantly. Appreciable amounts of calcium Ca was recorded 84.930 ppm in Artemisia herba-alba 1 while 30 ppm in Artemisia herba-alba 2, potassium (K) was 43.3 and 27.6 ppm in Artemisia herba-alba 1 and Artemisia herba-alba 2 respectively. Meanwhile, Fe was recorded as 0.39, 0.52 ppm in Artemisia herba-alba1 and 2. Level of total protein was 9.95 and 7.79 (mg/g) in Artemisia herba-alba 1 and Artemisia herba-alba 2 respectively. Present study found that the phenolic compounds were determined in both plants with high levels. The available data indicate the two plants were found to contain Alkaloids, essential oils, flavonoids, glycosides, phenolic compounds, sterols/triterpenes, and tannins. However, sterols/ triterpenes and coumarins were found in herba-alba 1  significantly, while Alkaloids, flavonoids, and Saponins found highest in herba-alba 2 compared to herba-alba 1 on the other side the quantity of essential oils was higher in the herba-alba 2.

Indian Medicinal Plants

Ayurveda is an age old system of medicine which utilizes thousands of medicinal plants, rich in secondary metabolites for their therapeutic benefits and phenolic compounds are important one. Plant phenolic compounds are one of the major group of phytomolecules having tremendous therapeutic and nutraceutical potential. Indian medicinal plants like Emblica, Terminalia spp., Withania, Tinospora etc. are some of the potential source of bioactive phenolics and had been used from ages in various Ayurvedic formulations and were scientifically validated too. In this contribution, a brief account of some common Indian medicinal plants rich in bioactive phenolics are summarized along with their therapeutic action on human health and disease. The vast array of phenolics in these plants makes them a suitable candidate for modern medicine, nutraceutical supplements, immuno-modulatory formulations etc. With the advent of modern separation tools and techniques, it is now possible to identify, isolate and purify desired phytoconstituents from plant extracts. This further opens the avenues of utilizing medicinal plants or plant constituents/metabolites as super food for strengthening the body and maintaining the healthy work-life balance. The need of the hour is to identify therapeutically potential phenolics rich plants and development of herbal formulations for human welfare.
