Maclura tinctoria (L.) D. Don ex Steud. has one of the highest qualities among the coefficients for Brazilian woods (up to 9.6) and resistance rates equivalent to Indian teak (Tectona grandis). In this study, the macromolecular constituents and total phenols compounds as well as the antioxidant and antibacterial activities of this wood were evaluated. Total phenols and proanthocyanidin levels w...

Extracts from wool dyed with sawwort (Serratula tinctoria L.) obtained with methanol/formic acid and methanol/hydrochloric acid solutions were examined by high-performance liquid chromatography with UV detection coupled with electrospray ionization tandem mass spectrometry. Chromatograms and mass spectra were registered in the negative ion mode under various orifice voltages and collision energ...

Technol., 2005, 27(Suppl. 2) : 455-467 The stems of Arcangelisia flava, Coscinium blumeanum and Fibraurea tinctoria, collectively known in southern Thailand as Khaminkhruea, w...

Wrightia tinctora is a tree widely used by the peoples of Tamil Nadu as a traditional medicine for pain and inflammations. Latex form the plant especially from leaves is directly applied on inflammation. This plant is very closely related to other species of Wrightia and hence pharmacognostical and preliminary phytochemical studies of Wrightia tinctoria leaves were carried out.

The essential oil (EO) of Cota tinctoria var. was analyzed using GC-FID / MS. A total 51 compounds were determined from this taxon, accounting for 99.79% in hydrodistillation. Monoterpenes the primary chemical class volatile organic EO (36.1%, 13 compounds). Borneol (18.1%), camphor (14.9%), and β-pinene (11.3%) major components C. tinctoria. antimicrobial activities n-hexane, acetonitrile, met...

Ninety solvent extracts (n-hexane, dichloromethane and methanol) obtained from the leaves, bark and stem of 13 Sri Lankan Rubiaceae and two Sri Lankan Meliaceae plants have been screened for antibacterial and antifungal activities. Morinda tinctoria, Mussaenda frondosa, Psychotria gardneri and Psychotria stenophylla displayed the widest spectrum of antibacterial activity.

Five conspicuous indole derivatives are present in leaves and other tissues of woad (Isatis tinctoria L.). They were identified as tryptophan, isatan B, glucobrassicin, neoglucobrassicin, and glucobrassicin-1-sulfonate. The latter three indole glucosinolates are present at levels of at least 260, 69, and 200 milligrams per kilogram fresh weight and were isolated as crystalline salts. Comparison...
