C-geranyl compounds from Paulownia tomentosa fruits.
Five geranylflavonoids, one prenylated flavonoid, and a simple flavanone were isolated from an ethanolic extract of Paulownia tomentosa fruit. Tomentodiplacol (1), 3'-O-methyl-5'-methoxydiplacol (2), 6-isopentenyl-3'-O-methyltaxifolin (3), and dihydrotricin (4) are reported from a natural source for the first time and 3'-O-methyldiplacone (6) for the first time from the genus Paulownia. The str...
متن کاملAntiradical activity of Paulownia tomentosa (Scrophulariaceae) extracts.
Paulownia tomentosa is a large indecidous tree planted mostly for its fast growing wood and decorative purposes. The tree is also used in traditional Chinese medicine. As a part of our study of natural polyphenols, the fruits of Paulownia tomentosa were extracted by EtOH and than subjected to liquid/liquid extraction. Fractions were analysed by TLC and HPLC to determine presence of phenolic sub...
متن کاملProduction of transgenic Paulownia tomentosa (Thunb.) steud. using chitosan nanoparticles to express antimicrobial genes resistant to bacterial infection
Paulownia tomentosa (Thunb.) Steud. is a very important hard woody plant, an extremely fast-growing tree and produce timber. Therefore, there is a demand to produce transgenic Paulownia plant resistant to bacterial infection. Microbial infection (especially bacterial one) is serious sever and cause a loss in plant productivity as they bear upon the character and amount of plan...
متن کاملSome technological properties and uses of paulownia (Paulownia tomentosa Steud.) wood.
The aim of this study is to determine some physical and mechanical properties of Paulownia tomentosa wood grown in Turkey. The samples trees harvested from Kargi in Corum. Physical properties including air-dry density oven-dry density basic density swelling, shrinkage and oven-dry and air-dry thermal conductivity coefficients; mechanical properties including bending strength, modulus of elastic...
متن کاملHistology of the regeneration of Paulownia tomentosa (Paulowniaceae) by organogenesis.
Paulownia tomentosa is a fast-growing tree species with a considerable economic potential because of its value for wood as well as its high biomass production, and elevated stress tolerance. The objective of the present study was to evaluate the development of adventitious buds in leaves obtained from four-week-old shoots of P. tomentosa, in order to identify the cells involved in in vitro adve...
