Physalis peruviana L. belongs to the family Solanaceae and is considered as plant used for treating various diseases. The protective mechanism of Physalis consists of the ability to scavenge reactive oxygen species (ROS) and to enhance the antioxidant system in the human body. The ethanolic extract of Physalis peruviana fruits contains valuable and active compounds such as carotenoids, phenols, flavonoids, tannin, alkaloids, vitamins C, B3 and B6. Therefore, Physalis peruviana extract has antioxidant and antimicrobial activity against gram-positive and gram-negative bacteria. Gram-positive Bacillus cereus demonstrated higher susceptibility than gram-negative Escherichia coli and Pseudomonas typhimureum. Also, the extract showed positive effect on the fungus used (Aspergillus niger and Candida albicans). In addition, high concentrations of Physalis peruviana ethanolic extract (800 g/ml) exhibited significant anticancer activity against lung (A549) cells but slight effect against colorectal adenocarcinoma (Caco-2) cells. 2019, Springer-Verlag GmbH Deutschland, ein Teil von Springer Nature.

Sesame (Sesamum indicum L.) from the family of Pedaliaceae is one of the most ancient crops and oilseeds. It was a major oilseed crop in the ancient world due to its easiness of extraction, great stability, and resistance to drought. One of the most dangerous pathogens that affect sesame and other plants worldwide is phytoplasma. Phytoplasma can cause different character of symptoms such as: phyllody, the common symptom caused by phytoplasma infection, stunting, changing the color of leaves from green to yellow and alteration of the floral parts into leafy structures bearing no capsule and seeds, which consider a serious threat for the production of sesame in many countries. On the other hand, effect of the phytoplasma infection on plant enzymes such as Peroxidase and Polyphenol oxidase and hormones like Auxins, Cytokinin, Gibberellins and Abscisic acid were studied. Electron microscopy assay was used to verify the cellular changes which conducted as a result of phytoplasma infection. Infected sesame samples which examined by PCR were used as an exporter of phytoplasma and directly applied for electron microscopy test and the analysis of enzymes and hormones. Transmission electron microscopy (TEM) was used to detect ultra-structural changes in infected sesame plants. � 2018 Parlar Scientific Publications. All rights reserved.

(Parlar Scientific Publications, 2018) El-Beltagi H.S.; Mohamed H.I.; Megahed B.M.H.; Gamal M.; Safwat G.; Faculty of Agriculture; Biochemistry Department; Cairo University; Giza; Cairo; Egypt; Cairo University; Research Park (CURP); Giza; Cairo; Egypt; Faculty of Education; Department of Biological and Geological Science; Ain Shams University; Cairo; Egypt; Faculty of Biotechnology; October University for Modern Science and Art (MSA); Egypt
Beta vulgaris is belonging to the family Chenopodiaceae and has several varieties with bulb colors ranging from yellow to red. Deep redcolored beet roots are the most popular for human consumption, both cooked and raw as salad or juice. The ethanolic extract of beetroots contains valuable and active compounds such as carotenoids, phenols, flavonoids, tannin, alkaloids, vitamins C, B3, B6 and B9. Therefore, beetroot extract has antioxidant and antimicrobial activity against gram positive and negative bacteria. Gram-positive bacteria Staphylococcus aureus and Bacillus cereus demonstrated higher susceptibility than Gramnegative Escherichia coli and Pseudomonas typhimureum. Beta vulgaris ethanolic extract exhibit significant anticancer activity against lung (A549) but slight effect against colorectal adenocarcinoma Caco-2 cell lines at the high concentrations of ethanolic extract (800 ?g/ml). � 2018 Malaysian Nature Society.

Plants have been used long ago through man history of life for their use in food and medicinal drives. In modern life, natural products have been extracted and isolated from several kinds of plants for the development of new drugs. There are numerous interests in natural antioxidants extracted from medicinal plants, vegetables and fruits, which might help to prevent oxidative damage. One of such plants is plum Prunus domestica L., family Rosaceae. Samples from 'African Rose', and 'Santa Rosa' plum cultivars were collected from local market in Giza governorate, Egypt. The main phytochemicals of plums (fruit flesh and skin) were analyzed. Total polyphenols, flavonoids, tannins, anthocyanins, and reducing power were higher in 'African Rose' fruit. The ethanolic and ethyl acetate extracts of two plum cultivars were both high in the antioxidant effect with IC50 13.923 and 18.416 ?g/ml of ethanolic extract of 'African Rose', and 'Santa Rosa' respectively. The IC50 of 'African Rose' and 'Santa Rose' extract against Caco-2 was 4 and 8.5 ?g/ml. GC-MS analysis was carried out, fourteen and twenty one compound were identified in 'Santa Rosa' and 'African Rose' respectively. The fruits had an antimicrobial action against gram positive and negative bacteria. There was anticancer activity against 3 cell lines: Liver cell line (HepG2), colorectal adenocarcinoma (Caco-2) cell line, and breast cell line (MCF-7). � 2018.
GC-MS analysis, antioxidant, antimicrobial and anticancer activities of extracts from Ficus sycomorus fruits and leaves

Higher plants have been utilized worldwide as characteristic drug a long time to cure human diseases. About 80% of individuals globally use plants as safe sources of medication to cure human diseases through completely different medicine system. One of the available indigenous medicinal plants, Ficus sycomorus belongs to the Moraceae family. The plant contains totally different teams of biologically active compounds that square measure chargeable for the biological activity. Ethanolic and ethyl acetate extracts of leaves of Ficus sycomorus contain higher concentrations of total phenols, flavonoids, tannins, alkaloids and steroids than the fruit extracts. Ethanolic extract in both fruits and leaves gave higher concentrations of phytochemical compounds than the ethyl acetate extracts. Therefore, fruit and leaves extract have antioxidant and antimicrobial activity against gram positive, negative bacteria and fungus. Also, the percentage of Liver cell line (HepG2), Colorectal adenocarcinoma (Caco-2) and Breast cell line (MCF-7) viability was decreased with increasing the concentrations of the ethanolic extract of fruits and leaves of Ficus sycomorus. The high concentrations of ethanolic extract of fruits caused high reduction in the viability of cancer cells, especially in Colorectal adenocarcinoma (Caco-2) cell line. In addition, phytochemical compound screened by GC-MS method. In GC-MS analysis, 12 bioactive phytochemical compounds were identified in fruits and 29 bioactive compounds were detected in leaves extract. These totally different active phytochemicals are found to possess a good vary of activities, which can facilitate within the protection against incurable diseases. � 2019, Academic Press.

Opuntia ficus-indica (L.) Mill is belonging to the family Cactaceae. The chemical composition of the pulp and peel of cactus showed that pulp has high content of proteins, moisture and lipid but low con-tent of total fiber and ash as compared to the peel. The peels of the cactus were considerably higher in fiber than the pulp. The ethanolic and ethyl acetate extracts of peel have high concentrations of total phenols, flavonoids, tannins, alkaloids than the pulp extracts. The ethanolic extract in both pulp and peel gave higher concentrations of phytochemical compounds than the ethyl acetate extract. Therefore, pulp and peel extract has antioxidant and antimicrobial activity against gram positive, negative bacteria and fungus. Also, the percentage of Liver cell line (HepG2), Colorectal adenocarcinoma (Caco-2) and Breast cell line (MCF-7) viability was decreased with increasing the concentrations of the ethanolic extract of the pulp and peel cactus (500, 1000, 1500, 2000, 3000 ^g/ml). The most pronounced reduction in the viability of cancer cells was detected after treatment with pulp extract than peel extract. The high concentrations of ethanolic extract of the pulp and peel cactus caused the high reduction in the viability of cancer cells especially in Liver cell line (HepG2). In addition, the phytochemical compound screened by GC-MS method. In this GC-MS analysis, 31 bioactive phytochemical compounds were identified in the pulp of cactus and 27 bioactive compounds were detected in peel extract. These different active phytochemicals have been found to possess a wide range of activities, which may help in the protection against incurable diseases. 2019 Parlar Scientific Publications.
