“…Also, the TPC in ethyl acetate and methanolic fractions of Cressa cretica 7.081 ± 1.033 and 12.833 ± 0.24 mg gallic acid equivalents (GAE)/g dry extract were obtained 8 . Similar results were reported in the plant extract of species Marrubium peregrinum 9 . The highest flavonoid concentration was observed in Senna italica leaves, and the lowest concentration was measured in Prosopis juliflora leaf extracts.…”

Four plant species Senna italica, Prosopis juliflora, Cressa cretica and Schouwia purpurea were selected to estimate phytoconstituents and quantify total phenols, tannins, and flavonoids. The total content of phenols, tannins, and flavonoids with the gallic acid curve by the standard method was estimated. The leaf extract of Senna italica contained maximum, and Schouwia purpurea contained a minimum amount of phenol. The maximum amount of tannins was found in Schouwia purpurea, and the minimum amount of flavonoids was recorded in Senna italica. It is further suggested that there are a need for systematic phytochemical, pharmaceutical and pharmacological investigations of these plants since there are less reports available. Moreover, these plants are accessible in abundant in Ballari region and can prove to be the best source for bioprospection studies since they contain high contents of phenols, tannins, and flavonoids.

Ironwort (Sideritis montana L.), mountain germander (Teucrium montanum L.), wall germander (Teucrium chamaedrys L.), and horehound (Marrubium peregrinum L.) are species widely distributed across Europe and are also found in North Africa and West Asia. Because of their wide distribution they express significant chemical diversity. For generations, these plants have been used as medical herbs for treating different aliments. The aim of this paper is to analyze volatile compounds of four selected species that belong to the subfamily Lamioideae, family Lamiaceae, and inspect scientifically proven biological activities and potential uses in modern phytotherapy in relation to traditional medicine. Therefore, in this research, we analyze the volatile compounds from this plants, obtained in laboratory by a Clevenger-type apparatus, followed by liquid–liquid extraction with hexane as the solvent. The identification of volatile compounds is conducted by GC-FID and GC-MS. Although these plants are poor in essential oil, the most abundant class of volatile components are mainly sesquiterpenes: germacrene D (22.6%) in ironwort, 7-epi-trans-sesquisabinene hydrate (15.8%) in mountain germander, germacrene D (31.8%) and trans-caryophyllene (19.7%) in wall germander, and trans-caryophyllene (32.4%) and trans-thujone (25.1%) in horehound. Furthermore, many studies show that, in addition to the essential oil, these plants contain phenols, flavonoids, diterpenes and diterpenoids, iridoids and their glycosides, coumarins, terpenes, and sterols, among other active compounds, which affect biological activities. The other goal of this study is to review the literature that describes the traditional use of these plants in folk medicine in regions where they grow spontaneously and compare them with scientifically confirmed activities. Therefore, a bibliographic search is conducted on Science Direct, PubMed, and Google Scholar to gather information related to the topic and recommend potential applications in modern phytotherapy. In conclusion, we can say that selected plants could be used as natural agents for promoting health, as a source of raw material in the food industry, and as supplements, as well as in the pharmaceutical industry for developing plant-based remedies for prevention and treatment of many diseases, especially cancer.

“…The quantitative contents of different phytochemicals were estimated with various methods. The Total Phenolic Content (TPC) was estimated using the Folin Ciocalteu method with some modification [14,15] . Gallic Acid Equivalent (GAE) per 50 g of fresh mass was calculated in finding plant's TPC with the help of formula:…”

Oxidative stress related disorders occur as a result of free radicals in the cellular organs. Antioxidants provide protection contrary to oxidative stress by counteracting free radicals through the help of different bioactive constituents present in the plants. The aim of this study is to find out the quantitative estimation of phytochemicals (phenolics, tannins, flavonoid, non-tannins, alkaloid and saponins), in vitro antioxidant activity (2, 2-diphenyl-1-picryl-hydrazyl-hydrate, metal chelating, ferric reducing, superoxide dismutase and total antioxidant activity) of different parts of Cyperus rotundus. Along with this, the extraction of polyphenolic compounds by conventional and non-conventional methods and their optimization by response surface methodology technique were also studied. As the outcomes of the study, maximum amount of total phenolics content was found in the ethanolic fraction of stem (37.88±0.94 mg gallic acid equivalent/g). The root has shown the highest flavonoid (0.24±0.03 mg QAE/g) and non-tannin content (21.55±2.43 mg gallic acid equivalent/g) in the extract of petroleum ether. The total alkaloids and tannin content in flower and root i.e., 5.05±0.08 mg caffeine equivalent/g and 76.28±0.62 mg tannic acid equivalent/g was found to be better in aqueous extract respectively. The fraction of ethyl acetate has reported the greatest saponin content (39.2±3.8 mg gallic acid equivalent/g). In case of flower part half-maximal inhibitory concentration value of 2, 2-diphenyl-1-picryl-hydrazyl-hydrate and superoxide dismutase antioxidant activity varies from 0.57-1.90 mg/ml and from 0.053-1.401 mg/ml respectively. Antioxidant activity of each part of the plant was reported in the fraction of ethanol and water by fluorescence recovery after photobleaching (0.403±0.009-0.886±0.02 mg/ml), metal chelation activity (0.010±0.0-0.306±0.001 mg/ml) and total antioxidant capacity (0.030±0.0-0.317±0.002 mg/ml). Microwave assisted extraction method was found to be the suitable one for optimization of total phenolic content. So, the relationship between different parameter was determined through response surface methodology technique and evaluated by plotting the graphs. Polar extracts have found to show the maximum quantity of secondary bioactive metabolites and antioxidant activity as compared to non-polar one. And among the comparison between conventional and non-conventional methods, ultra sonication (nonconventional method) has shown the highest yield of bioactive phenolic compound. So, this study shows that Cyperus rotundus has wide range of secondary metabolites showing antioxidant properties that can be applied for different therapeutic applications.
