Phytochemical research based on ethnopharmacology is gaining interest in industries such as functional food, nutraceuticals, cosmetics and pharmaceutical industries. Plants and plant extracts are a rich source of bioactive secondary metabolites. These compounds are often involved in plant protection against biotic or abiotic stresses. The exploitation of available technologies should be oriented and intensified to extend and enhance the continued usefulness of the plants as renewable sources of chemicals, especially medicinal compounds. This current contribution is focused on extraction and analytical techniques for their isolation from the oregano species, their characterization and their potential antioxidative, as well as their antimicrobial, antifungal and anticarcinogenic properties. The work is structured rendering to the different steps involved in the research; starting with extraction and sample preparation, followed by discussing the analytical techniques employed for the isolation and identification of compound/s responsible for the biological activity and methods and techniques for biological activity assessment.

The evolution of semiconductor from the conventional type to organic semiconductor has not convincingly shown that it is eco-friendly both in the short and long term. This research presents the green solution bio-semiconductor that was synthesized from zinc coated carica papaya. It was observed that carica papaya extracts do not respond significantly to the extracting solution (methanol, ethanol and butanol). The band gap of sample 1 (extract in methanol solution), sample 2 (extract in ethanol solution) and sample 3 (extract in butanol solution) was calculated as 1.98 eV, 2.01eV and 1.93 eV respectively. Further research is therefore recommended for the perfection of the bio-semiconductor.

The present examination was done for assurance of the microbial colors present in the blend of Citrus limon (strip) and Carica papaya (pulp) is the restoratively significant plant having a place with the Rutaceae and Caricaceae family individually. In the present investigation, the concentrate of Citrus limon strip with Carica papaya mash has been exposed to aging by utilizing Pencillium purpurogenum and broke down by explanatory systems. This investigation uncovered that microbial concentrate of Citrus limon and Carica papaya contains Silanediol dimethyl, 3-furaldehyde, 4-hepten-3-one, 3-undecen-5-yne, 3-cyclohexon-ol, 3,4,5-Trimethylpyrano[2,3-c]pyrazol-6(1H)-one, N-didehydrohexacarboxyl-2,4,5-trimethylpiperazine, 6,10-Dimethoxy-3,3-dimethyl-1-(methylsulfanyl) - 2-aza-spiro [4.5] deca-1,6,9-trien-8-one, 9-octadecenoic corrosive, 2H-1-benzopyran-2-one, Di-n-octyl phthalate, 2-[2-(4-chloro-phenyl)- vinyl]-1-(2-phenoxy-ethyl)- 1h-benzoimidazole, lilial, Cyclohexane, and 3',4',5,6,7,8-Hexamethoxyflavone defending the utilization of this plant to treat numerous aliments in society and homegrown prescription.

AIMS: This study aimed to investigate the effects of crude extract of Carica papaya leaves on oxidative stress in mice induced by cyclophosphamide, as well as phytochemical profile characterization of this extract.METHODS: The male Swiss mice received 15 days of treatment with the extract (500 mg kg-1, via gavage) and intraperitoneal injection of cyclophosphamide (75 mg kg-1) or saline (0.9%) on the 15th day. After 24 h the last treatment, the animals were anesthetized for blood withdrawal, sacrificed and removal of the organs for analyses (liver, kidney and heart). In the biochemical tests were determined: hematological parameters in blood, aminotransferases, alkaline phosphatase, glucose and total cholesterol dosages in plasma, enzymatic and non-enzymatic antioxidants and lipid damage marker were evaluated in different tissues, besides genotoxic and histopathological analyzes.RESULTS: In the extract of Carica papaya leaves, the flavonoids quercetin-3β-D-glucoside and rutin were identified, besides present positive results for alkaloids, saponins and tannins. This extract increased the activity of glutathione-S-transferase and catalase enzymes in the liver and reduced the levels of reduced glutathione in the kidneys and hematocrit levels, red cell count, and hemoglobin. It promoted the decrease of the reactive species of thiobarbituric acid (TBARS) in the kidneys and the activity of enzyme aspartate aminotransferase in the plasma and was antimutagenic in the micronucleus test.CONCLUSIONS: The study showed that extract of Carica papaya was beneficial against oxidative events and prevented DNA damage. The extract also showed hepatotoxicity, therefore prolonged infusion of papaya leaves is not advisable.
