Epilepsy is a most disabling neurological disorder affecting all age groups. Among the various mechanisms that may result in epilepsy, neuronal hyperexcitability and oxidative injury produced by an excessive formation of free radicals may play a role in the development of this pathology. Therefore, new treatment approaches are needed to address resistant conditions that do not respond fully to current antiepileptic drugs. This paper reviews studies on the anticonvulsant activities of essential oils and their chemical constituents. Data from studies published from January 2011 to December 2018 was selected from the PubMed database for examination. The bioactivity of 19 essential oils and 16 constituents is described. Apiaceae and Lamiaceae were the most promising botanical families due to the largest number of reports about plant species from these families that produce anticonvulsant essential oils. Among the evaluated compounds, β-caryophyllene, borneol, eugenol and nerolidol were the constituents that presented antioxidant properties related to anticonvulsant action. These data show the potential of these natural products as health promoting agents and use against various types of seizure disorders. Their properties on oxidative stress may contribute to the control of this neurological condition. However, further studies on the toxicological profile and mechanism of action of essential oils are needed.

Eucommia ulmoides(EU) (also known as “Du Zhong” in Chinese language) is a plant containing various kinds of chemical constituents such as lignans, iridoids, phenolics, steroids, flavonoids, and other compounds. These constituents of EU possess various medicinal properties and have been used in Chinese Traditional Medicine (TCM) as a folk drink and functional food for several thousand years. EU has several pharmacological properties such as antioxidant, anti-inflammatory, antiallergic, antimicrobial, anticancer, antiaging, cardioprotective, and neuroprotective properties. Hence, it has been widely used solely or in combination with other compounds to treat cardiovascular and cerebrovascular diseases, sexual dysfunction, cancer, metabolic syndrome, and neurological diseases. This review paper summarizes the various active ingredients contained in EU and their health-promoting properties, thus serving as a reference material for the application of EU.

Food processing generates a large amount of bio-residues, which have become the focus of different studies aimed at valorizing this low-cost source of bioactive compounds. High fruit consumption is associated with beneficial health effects and, therefore, bio-waste and its constituents arouse therapeutic interest. The present work focuses on the main Portuguese fruit crops and revises (i) the chemical constituents of apple, orange, and pear pomace as potential sources of functional/bioactive compounds; (ii) the bioactive evidence and potential therapeutic use of bio-waste generated in the processing of the main Portuguese fruit crops; and (iii) potential applications in the food, nutraceutical, pharmaceutical, and cosmetics industries. The current evidence of the effect of these bio-residues as antioxidant, anti-inflammatory, and antimicrobial agents is also summarized. Conclusions of the revised data are that these bio-wastes hold great potential to be employed in specific nutritional and pharmaceutical applications.

Natural products are the main source for an alternative system of medicine. Ziziphus mauritiana, commonly known as jujubes, belongs to the family Rhamnaceae and is majorly found in the Indian subcontinent. They are traditionally used to treat chronic bronchitis, insomnia, diabetes, diarrhoea, abscesses, wounds, liver diseases, fever, sleeplessness, constipation, urinary diseases, and abdominal pains. Over the course of many years, various parts of Ziziphus mauritiana has been found to possess hair growth stimulating, anti-platelet aggregating, anti-inflammation, wound-healing, anti-obesity, antibacterial, and antioxidant effects. Various peer-reviewed research articles were collected from SCOPUS, PubMed, Google, Research Gate, and Web of Science databases. A total of 26 papers were selected based on their relevance. Acetyljujuboside B, Mauritine A, and Jujuboside A are some of the numerous chemical constituents present in Ziziphus mauritiana. The present review is an effort to provide a comprehensive review of the literature on the health-promoting effects of Ziziphus mauritiana.

Open column chromatography is an effective and common technique for the separation and purification of chemical constituents. Limonoids are found in significant quantities in citrus fruits. Citrus limonoids have documented anti-cancer activity in several types of cancer, such as breast, colon, skin, and neuroblastoma in animal models and in vitro cell culture studies. Furthermore, limonoids have shown anti-inflammatory properties and inhibitory effects on bone resorption. In addition to many potential health benefits, limonoids have also shown antifungal and insect anti-feedant properties. To meet the large demand of limonoids for bioactivity studies, defatted grapefruit seeds were extracted using acetone and concentrated under vacuum. The dried extract was loaded onto a silica gel column and eluted with mixtures of dichloromethane and ethyl acetate with increasing polarity to obtain three compounds. The purity of the compounds (1–3) have been analyzed by HPLC and the structures have been identified by using NMR spectra and mass spectra as nomilin, limonin, and deacetylnomilin, in respective order of elution. The results will be presented in greater detail on the poster. This project is based upon work supported by the USDA-CSREES under Agreement USDA IFAFS #2001 52102 02294 and USDA #2005-34402-14401 “Designing Foods for Health” through the Vegetable & Fruit Improvement Center.

Newbouldia laevis (P. Beauv.) Seem. (Family, Bignoniaceae), commonly known as tree of life, is a purple-flowering plant that is widely distributed in many parts of Africa. Different parts of the plant, including the leaves, flower, stems and roots are prevalently used in African traditional medicine for the management of many diseases and conditions like diabetes, hypertension, skin diseases, ulcer, tumors, pains, infectious diseases, inflammation, dysentery, sickle cell disease and impotency. This review discusses the trado-medical uses, chemical constituents, and biological activities of N. laevis. Based on information generated from scientific investigations deposited in PubMed and SCOPUS, the chemical constituents of the plant include glycosides, anthraquinolones, volatile oils, tannins, steroids, alkaloids, flavonoids, terpenoids and sterols. Extracts different parts of the plant and compounds isolated from them have been reported to have several health-promoting potentials such as antioxidant, antimalarial, trypanocidal, antimicrobial, anthelmintic, analgesic, anti-inflammatory, antidiabetic, anti-arthritic, anti-thrombotic, cytoprotective, anti-hypertensive, central nervous system modulatory, male reproduction enhancing and oxytocic properties. These scientific investigations have led credence to the ethnobotanical uses of the plant in folkloric practice. In addition, the presence of phytochemical constituents in the plant might be responsible for the wide biological potentials.

The mammary gland ultrastructure in various functional states is the object of our investigations. The material prepared for electron microscopic examination by the conventional chemical methods has several limitations, the most important are the protein denaturation processes and the loss of large amounts of chemical constituents from the cells. In relevance to this,one can't be sure about a degree the observed images are adequate to the realy ultrastructure of a living cell. To avoid the disadvantages of the chemical preparation methods,some autors worked out alternative physical methods based on tissue freezing / freeze-drying, freeze-substitution, freeze-eatching techniqs/; actually the technique of cryoultraraicrotomy,i,e.cutting ultrathin sections from deep frozen specimens is assented as a complete alternative method. According to the limitations of the routine plastic embbeding methods we were interested to analize the mammary gland ultrastructure during lactation by the cryoultramicrotomy method.

Analysis of the constituents of renal and biliary calculi may be of help in the management of patients with calculous disease. Several methods of analysis are available for identifying these constituents. Most common are chemical methods, optical crystallography, x-ray diffraction, and infrared spectroscopy. The application of a SEM with x-ray analysis capabilities should be considered as an additional alternative.A scanning electron microscope equipped with an x-ray “mapping” attachment offers an additional dimension in its ability to locate elemental constituents geographically, and thus, provide a clue in determination of possible metabolic etiology in calculus formation. The ability of this method to give an undisturbed view of adjacent layers of elements in their natural state is of advantage in determining the sequence of formation of subsequent layers of chemical constituents.
