Anti-TMV activity flavones from the leaves of Yunnan local air cured tobacco

Fitoterapia, 2015
Four new flavones, tobaflavones E-H (1-4), together with two known flavones (5 and 6), were isolated from the leaves of Dali Tiandeng tobacco (a variety of Yunnan local air cured tobacco). Their structures were elucidated by spectroscopic methods, including extensive 1D- and 2D NMR techniques. Compound 2 is the first naturally occurring flavone bearing

Seco-pregnane steroidal glycosides from the roots of Cynanchum atratum and their anti-TMV activity

Fitoterapia, 2014
Fifteen new seco-pregnane steroidal glycosides cynanosides A-O (1-15) together with twenty-seven known ones were isolated from the roots of Cynanchum atratum. The structures of 1-15 were determined by extensive analysis of spectroscopic data. The anti-tobacco mosaic virus (TMV) activity of these steroidal glycosides was screened by the conventional ...

Polysaccharide from discarded tobacco leaves and its anti-TMV activities

Pesticide Biochemistry and Physiology
Natural polysaccharides have been attracted increasing attention in biopesticides for the antiviral effects. Tobacco leaves enriched the polysaccharides and had the potential against tobacco mosaic virus (TMV), however, the chemical structure and anti-TMV effect of polysaccharides from discarded tobacco leaves (DTCP) are still unclear.

Three new xanthones from the stems of Garcinia oligantha and their anti-TMV activity

Phytochemistry Letters, 2013
Abstract For more bioactive compounds, phytochemical investigations of the acetone extract of the stems of Garcinia oligantha resulted in the isolation of three new xanthones ( 1 – 3 ) and five known analogues ( 4 – 8 ). Structural elucidations of 1 – 3 were performed by spectral methods such as 1D and 2D (HMQC, HMBC, and ROESY) NMR spectroscopy,

C‐Alkylated flavonoids from the whole plants of Desmodium caudatum and their anti‐TMV activity

Pest Management Science, 2023
AbstractBackgroundNatural products are important sources of biopesticides to control plant virus, and flavonoids are identified as promising anti‐tobacco mosaic virus (TMV) agents. Since Desmodium caudatum is a rich source of flavonoids, this study focuses on the discovery of the new anti‐TMV active flavonoids from D.
