Missing data

Among all African propolis sample tested, Cameroonian propolis was the most potent.

All extracts contain phenolic compounds and present antiradical activities Antioxidant capacities: the order of decreasing antiradical activity is Water > Methanol > Ethanol

Propolis Ngaoundere (2004)

Ethanol (missing data)

Total polyphenols (mg/L) 10.99 ± 2.56; Tannins (mg/L): 1.57 ± 1.62

The Cameroonians propolis exhibited higher scavenging (antiradical activity (%):83.4 ± 2.3); activity which could justify their commercialisation and role in the management of some chronic diseases

Propolis Ngaoundere (2003)

Ethanol (missing data)

Total polyphenols (mg/L) 227.8 ± 36.0; Tannins (mg/L): 16.3 ± 12.6 (PROMAX-C, 2003)

Total polyphenols (mg/L) 772.8 ± 270.2; Tannins (mg/L): 453.8 ± 361.5 in PROMAX-C of 2006

All PROMAX-C samples tested showed evidence of radical scavenging properties with values ranging from 28 to 70%. Radical scavenging activity: Antiradical activity (%):43.7 ± 13.8 for PROMAX-C made in 2003 and Antiradical activity (%):67.3 ± 3.0 for PROMAX-C made in 2006.

Most active than PROMAX-C from Meiganga with a most higher phenolic content

Antibacterial activity against gram positive bacterial strain tested except Enterococcus faecalis. This propolis was the most active and content more phenolic compounds than other tested propolis.
