A novel compound (2) and a known one (1) were isolated from the mushroom, Sparassis crispa. Both compounds inhibited melanin synthesis and MRSA growth.

Beauvericin is a cyclic hexadepsipeptide mycotoxin, which has insecticidal, antimicrobial, antiviral and cytotoxic activities. It is a potential agent for pesticides and medicines. This paper reviews the bioactivity, fermentation and biosynthesis of the fungal product beauvericin.

Research on natural and bioactive compounds is increasingly focused on their effects on human health, but there are unexpectedly few studies evaluating the relationship between climate and natural antioxidants. The aim of this study was analyze the biological role of six different Brassica vegetables (Brassica oleracea L. and Brassica rapa L.) as a natural source of antioxidant compounds. The a...

OBJECTIVES The purpose of this study was to obtain a natural antibiotic from Phenol-rich compounds; for the dressing and the treatment of chronic wounds. METHODS The Phenol-rich compound sweet gel was prepared by blending four natural herbal extracts, Acacia catechu (L.F.), Momia (Shilajit), Castanea sativa, and Ephedra sinica stapf, with combination of a sweet gel medium, including honey, ma...

The investigation of Thai medicinal plants for the potential therapeutic agents is surveyed with a particular emphasis on the search for antimalarial agents. The study on Diospyros mollis, Croton sublyratus, and Phyllanthus amarus is described. Thailand is uniquely located to represent the fauna and flora which characterizes the biogeographic province of Indo-Burma. A number of the eastern Hima...

Isolation of a number of bioactive compounds from medicinal plants such as acetylcholinesterase inhibiting steroidal alkaloids, homomoenjodaramine and moenjodaramine from Buxus hyrcana, anti-epileptic terpenoids delphadienones I and II from Delphinium denudatum, and potent leishmanicidal compound ajoene from Allium sativum have been achieved through bioactivity-guided isolation.

Reactive oxygen species (ROS), as well as reactive nitrogen species (RNS) play either harmful or beneficial role in biological systems. Beneficial effects of ROS include physiological roles in cellular responses against infectious agents and in several cellular signalling pathways. Harmful effects are due to high concentrations of ROS, which can damage biomolecules, including lipids, proteins a...

It is well known that plants are important sources for the preparation of natural remedies as they contain many biologically active compounds. In particular, polyphenols, terpenic compounds, organic acids, and vitamins are the most widely occurring groups of phytochemicals. Some endemic species may be used for the production of herbal preparations containing phytochemicals with significant bioa...
