CHEMICAL CONSTITUENTS AND EVALUATION OF ANTIOXIDANT AND ANTI-INFLAMMATORY ACTIVITIES OF ROOTS OFSabicea brasiliensisWernh (Rubiaceae).

Abstract: Sabicea brasiliensis Wernh (Rubiaceae). The phytochemical investigation of Sabicea brasiliensis roots led to the isolation of 5-O-caffeoylquinic acid, 3,5-and 4,5-O-dicaffeoylquinics acids, scopoletin, ursolic acid, a mixture of β-sitosterol, stigmasterol and campesterol, daucosterol and saccharose. The structures of the isolated compounds were assigned on the basis of one-and twodimensional NMR spectroscopic methods and by comparison with literature data. The anti-inflammatory and antioxidant activities of th… Show more

“…It is already described the presence of caffeic acid derived molecules in Sabicea brasilinesis roots, such as 5-O-caffeoylquinic, 4,5 and 3,5-Odicaffeoylquinic acids [6]. Caffeoylquinic acids are the most widely available polyphenols consumed and exhibit antioxidant potential and anti-inflammatory effects [23,24].…”

“…Besides, the AA of S. brasiliensis CE, EAF and HMF exhibited a strong and positive correlation with their phenolic content (DPPH, r = 0.99 and ABTS, r = 0.90, respectively to p < 0.05), suggesting that the reduction of free radicals comes from the ability of phenolic and polyphenolic compounds present in these samples in donating hydrogen atoms. The preservation of the already characterized caffeic acid derived molecules in EAF samples, such as 5-O-caffeoylquinic, 4,5 and 3,5-Odicaffeoylquinic acids [6] may account for the best performance of CE and EAF regarding AA and the positive correlation with total phenolic compounds. Some plants from the Brazilian Cerrado are reported to present antiulcerogenic, antidiabetic, anti-inflammatory and antitumoral activities based in the action of their bioactive compounds as free radical scavengers.…”

“…Table 1 shows the retention times (Rt) as well as the 1 H NMR chemical shift values of the isolated compounds. References: [3,4,5] Mass spectrometry analysis was of great relevance for analyzing the intensities of the isomer fragments and the values were compared with studies by De Maria and Moreira (2004) and Jaiswal and Kuhnert [6,7].…”
