Tobacco mosaic virus (TMV) infection has been studied in several investigations of Nicotiana tabacum leaf tissue. Earlier studies have suggested that TMV infection does not have precise infective selectivity vs. specific types of tissues. Also, such tissue conditions as vein banding, vein clearing, liquification and suberization may result from causes other than direct TMV infection. At the present time, it is thought that the plasmodesmata, ectodesmata and perhaps the plasmodesmata of the basal septum may represent the actual or more precise sites of TMV infection.TMV infection has been implicated in elevated levels of oxidative metabolism; also, TMV infection may have a major role in host resistance vs. concentration levels of phenolic-type enzymes. Therefore, enzymes such as polyphenol oxidase, peroxidase and phenylalamine ammonia-lyase may show an increase in activity in response to TMV infection. It has been reported that TMV infection may cause a decrease in o-dihydric phenols (chlorogenic acid) in some tissues.

Background: Vitex negundo Linn. commonly known as five leave chase tree is an ethnobotanically important drug in traditional system of medicine. The plant is widely distributed in India, China and other Asian and American countries. Objective: The review aims at presenting comprehensive information with respect to ethnopharmacological rele-vance and recent findings on phytochemical and biological activities of Vitex negundo. Method: Literature was collected from various sources such as pubmed, scopus, science direct, and others. Results: Extracts and secondary metabolites of this plant, particularly those from roots and leaves, possess useful pharmacological activities such as anti-inflammatory, antitumor, antioxidant, antimicrobial, galactagogue, antigas-tric, antiflatulant, antiparasitic, analgesic, hepatoprotective and antihypertensive, some of which have been vali-dated scientifically. All parts of plant especially leave and roots contain a large number of bioactive phytoconstitu-ents including flavonoids, iridoids, lignans, volatile oil, terpenes, coumarins, phenolic and steroidal compounds which impart it multiple medicinal properties. Vitexin, isovitexin, viridifol, caffeic acid, chlorogenic acid and iso-chlorogenic acid are the main components. Conclusion: The review emphasises the medicinal importance of Vitex negundo and its bioactive constituents in traditional system of medicine.

AbstractThe effects of chlorogenic acid and quercetin-3-D-galactoside on the decomposition of trimethylamine oxide (TMAO) in squid extract and the main mechanism of inhibition of thermal decomposition were studied. The results indicated that chlorogenic acid and quercetin-3-D-galactoside could inhibit decomposition of TMAO in squid extract. The amount of TMAO was increased by 11.79 and 15.76% in squid extract treated with chlorogenic acid and quercetin-3-D-galactoside from 0 and 2.5 g/L, respectively. The contents of trimethylamine (TMA), dimethylamine (DMA), and formaldehyde (FA) were significantly decreased with increasing contents of chlorogenic acid and quercetin-3-D-galactoside. There were many free radicals in squid extract at high temperatures; however, the free radical signals were weakened after the addition of chlorogenic acid and quercetin-3-D-galactoside therein. This implied that chlorogenic acid and quercetin-3-D-galactoside could inhibit the thermal decomposition of TMAO in squid extract, which was associated with the scavenging of their free radicals. This result provides a theoretical basis for the development and utilization of blueberry leaf extract as an efficient FA inhibitor for aquatic products.
