In Vitro TNF- Inhibitory Activity of Brazilian Plants and Anti-Inflammatory Effect of Stryphnodendron adstringens in an Acute Arthritis Model

Figure 3

Chromatograms obtained for the organic fraction (SAO) of Stryphnodendron adstringens, registered by photodiode array detector (PDA) at 220 nm (a) and by electrospray ionization mass spectrometry (ESI-MS) in the negative ion mode of analysis (b). Identified peaks: 1, gallic acid, 2, dimer [two units of (epi)gallocatechin], 3, gallocatechin, 4, dimer [two units of (epi)gallocatechin gallate], 5, dimer [methyl-(epi)gallocatechin gallate and (epi)gallocatechin gallate], 6, epigallocatechin, 7, dimer [(epi)gallocatechin and (epi)gallocatechin gallate], 8, 4′-O-methyl-gallocatechin, 9, dimer [two units of (epi)gallocatechin gallate], 10, epigallocatechin 3-O-gallate, 11, dimer [methyl-(epi)gallocatechin and (epi)gallocatechin], and 12, methyl-(epi)gallocatechin gallate.
