Deeksha Sharma, Avijit Pramanik, Pavan Kumar Agrawal
Six endophytic fungi were isolated from Cupressus torulosa D.Don and identified phenotypically and genotypically. The fungal cultures were further grown and the culture was extracted by two organic solvents methanol and ethyl acetate. The screening was carried out using the agar well diffusion method against human pathogen such as Escherichia coli, Salmonella typhimurium, Bacillus subtilis and Staphylococcus aureus. Isolated strain of Pestalotiopsis sp. was showing prominent antibacterial activity. The crude methanol and ethyl acetate extract of Pestalotiopsis sp...

Moringa oleifera Lam., also known as the 'drumstick tree,' is recognized as a vibrant and affordable source of phytochemicals, having potential applications in medicines, functional food preparations, water purification, and biodiesel production. The multiple biological activities including antiproliferation, hepatoprotective, anti-inflammatory, antinociceptive, antiatherosclerotic, oxidative DNA damage protective, antiperoxidative, cardioprotective, as well as folk medicinal uses of M. oleifera (MO) are attributed to the presence of functional bioactive compounds, such as phenolic acids, flavonoids, alkaloids, phytosterols, natural sugars, vitamins, minerals, and organic acids...

Artemisinin and its derivatives are still one of the most effective drugs for the treatment of malaria. Artemisia pallens commonly known as Dhavanam, is an aromatic herb belonging to the family Asteraceae. Increasing the artemisinin content of A. pallens by genetic engineering would improve the availability of this much needed drug. In the present study, Agrobacterium rhizogenes (strain NCIM 5140) mediated genetic transformation of Artemisia pallens were carried out for hairy root induction. The effect of different media (Half MS, MS, MS along with BAP 0...

Food insecurity is a major issue in current scenario where a large section of mankind is at risk of insufficient diet. As food productivity has its limits, the prospecting of unutilized or underutilized flora as food candidates is collectively recognized as a sustainable option. In the past decade, a number of obscure plants have been identified to be rich in dietary components and deemed fit for integration into the food platter. This review discusses a candidate Salicornia, belonging to family Amaranthaceae...

Methanolic and dichloromethane extracts from the leaves of Congolese Hibiscus species were characterised by chromatographic and spectroscopic techniques and their in vitro biochemical activities against ROS production were evaluated in cellular models and on an enzyme, myeloperoxidase (MPO), involved in inflammation. Hibiscus acetosella has a chemical fingerprint different from Hibiscus cannabinus and Hibiscus sabdariffa both having similar fingerprints. Major compounds were polyphenols, represented mainly by caffeoyl-hydroxycitric acid for H...

BACKGROUND: Anogeissus leiocarpus and Hunteria umbellata have been reportedly used in traditional medicine for the management of erectile dysfunction (ED). However, the scientific basis for their use has not been well established. Therefore, this study was designed to investigate the inhibitory effects of water extractable phytochemicals of H. umbellata and A. leiocarpus on phosphodiesterase-5 (PDE-5) and arginase as well as pro-oxidants induced lipid peroxidation in rat penile tissue...

Peumus boldus Mol. ("Boldo") and Cryptocarya alba Mol. Looser ("Peumo") are medicinal shrubs with wide geographical distribution in South America. Their leaves and fruits are commonly used in traditional medicine because they exhibit natural medicinal properties for treatment of liver disorders and rheumatism. However, there are no apparent data regarding potential protective effects on cellular genetic components. In order to examine potential mutagenic and/or antimutagenic effects of these medicinal plants, the Drosophila melanogaster (D...

Parkinson´s disease is a neurodegenerative disease caused by the loss of dopaminergic neurons in the substantia nigra pars compacta region. An important mechanism contributing to its development is oxidative stress, induced by the imbalance between the endogenous antioxidant defenses and free radicals production. Naturally occurring bioactive compounds exhibit high antioxidant capacity that may help reducing oxidative stress and even reverse the damage induced by ROS. Fruits are particularly rich in phytochemicals with antioxidant effect, and their properties against the development of neurodegenerative diseases are of great interest...

Although the rhizomes of Rheum nobile Hook. f. et Thoms (Polygonaceae) are widely used in Tibetan medicine, no previous investigations regarding the biological activities and rarely chemical constituents of this plant have been reported. As part of an ongoing search for novel bioactive agents, a phytochemical investigation of R. nobile led to the isolation of two new compounds Rheumone B (1) and piceatannol-4'-O-β-D-(6″-O-acetyl)-glucoside (2), together with 15 known compounds by gel filtration over Sephadex LH-20 and preparative HPLC...

Virulence factors regulated by quorum sensing (QS) play a critical role in the pathogenesis of an opportunistic human pathogen, Pseudomonas aeruginosa in causing infections to the host. Hence, in the present work, the anti-virulence potential of the medicinal plant extracts and their derived phytochemicals from Myrtaceae family was evaluated against P. aeruginosa. In the preliminary screening of the tested medicinal plant extracts, Syzygium jambos and Syzygium antisepticum demonstrated a maximum inhibition in QS-dependent violacein pigment production by Chromobacterium violaceum DMST 21761...

Induction of tetraploidy was performed and podophyllotoxin production increased by upregulating the expression level and enzyme activity of genes related to its biosynthesis in tetraploid compared to diploid Linum album. Linum album is a valuable medicinal plant that produces antiviral and anticancer compounds including podophyllotoxin (PTOX). To achieve homogeneous materials, in vitro diploid clones were established, and their nodal segments were exposed to different concentrations and durations of colchicine...

Today, by-products generated from the agro-industrial practices are considered a key source of bioactive and functional components, that can be used for their nutritional and added value properties. New aspects concerning the use of these wastes as by-products in food production additives or supplements with high nutritional and medicinal value have gained substantial interest, due to their possession of economically high-value products. In this sense, the present study describes a thorough characterization of phytochemical compounds from hydro-methanolic extract of broad beans testa by using ultra-high performance liquid chromatography (UHPLC) hyphenated with quadrupole-time-of-flight tandem mass spectrometry (QTOF-MS)...

Members of the genus Lathyrus are used as food and as traditional medicines. In order to find new sources of biologically-active compounds, chemical and biological profiles of two Lathyrus species (L. czeczottianus and L. nissolia) were investigated. Chemical profiles were evaluated by HPLC-ESI-MS(n), as well as by their total phenolic and flavonoid contents. In addition, antioxidant, enzyme inhibitory, and cytotoxic effects were also investigated. Antioxidant properties were tested by using different assays (DPPH, ABTS, CUPRAC, FRAP, phosphomolybdenum, and metal chelation)...
