In vivo anti-inflammatory activity of BACCHARIN from BRAZILIAN green PROPOLIS.

Baccharin is one of the major compounds found in Brazilian green propolis and its botanical source, Baccharis dracunculifolia. Considering the biological effects of propolis and B. dracunculifolia, this study aims to evaluate the analgesic and anti-inflammatory potential of baccharin.

Alternative chelating agents: evaluation of the ready biodegradability and complexation properties.

The ready biodegradability of four chelating agents, N,N'-(S,S)-bis[1-carboxy-2-(imidazol-4-yl)ethyl]ethylenediamine (BCIEE), N'-ethylenedi-L-cysteine (EC), N,N'-bis (4-imidazolymethyl)ethylenediamine (EMI) and 2,6-pyridine dicarboxylic acid (PDA), was tested according to the OECD guideline for testing of chemicals. PDA proved to be a readily biodegradable substance. However, none of the other three compounds were degraded during the 28 days of the test.
