Beyerane derivatives and a sesquiterpene dimer from Japanese Cypress (Chamaecyparis obtusa).
In the course of studies on biological active constituents from woody plants, we previously reported the isolation of many lignan derivatives as neurite outgrowth-promoting compounds from an ethyl acetate soluble fraction of Japanese Cypress (Chamaecyparis obtusa). Further chemical investigation on the residual parts of the ethyl acetate soluble fraction of a methanol extract of Japanese Cypres...
متن کاملNeurite outgrowth-promoting active constituents of the Japanese cypress (Chamaecyparis obtusa).
In the screening of biologically active constituents from woody plants, the methanol extract of leaves of Chamaecyparis obtusa showed potent neurite outgrowth-promoting activity in neuronal PC12 cells. The ethyl acetate-soluble fraction of the methanol extract showed potent activity and was separated by means of various chromatographic methods to give the two new compounds 1 and 2, as well as 1...
متن کاملEffects of Essential Oil from Hinoki Cypress, Chamaecyparis obtusa, on Physiology and Behavior of Flies
Phytoncides, which are volatile substances emitted from plants for protection against plant pathogens and insects, are known to have insecticidal, antimicrobial, and antifungal activities. In contrast to their negative effects on microorganisms and insects, phytoncides have been shown to have beneficial effects on human health. Essential oil from Hinoki cypress (Chamaecyparis obtusa) is mostly ...
متن کاملBiflavones from Chamaecyparis obtusa.
From the leaves of Chamaecyparis obtusa several biflavones were isolated and identified, namely: sciadopitysin, ginkgetin, isoginkgetin, podocarpusflavone B, 7,7"-O-dimethylamentoflavone, bilobetin, podocarpusflavone A, and 7-O-methylamentoflavone. The presence of amentoflavone and hinokiflavone was also confirmed. The composition of biflavones in other Chamaecyparis species--Ch. lawsoniana, Ch...
متن کاملRemoval efficiency of Enzyme Horseradish Peroxidase in Removal of Tetracycline and Ciprofloxacin from Synthetic Wastewater
Background and purpose: So far, different methods have been used to remove residual antibiotics from aquatic environments. This study investigated the efficiency of enzyme horseradish peroxidase (HRP) in presence of hydrogen peroxide in removal of Tetracycline and Ciprofloxacin in a batch system. Materials and methods: In an experimental study on laboratory scale, the effects of contact time, ...
