From: Ethanol-extracted Cameroonian propolis exerts estrogenic effects and alleviates hot flushes in ovariectomized Wistar rats

Propolis samples (Year) Solvant of extraction (Yield) Phytochemical constituent Biological activities References
Propolis Meiganga (2003 & 2005) Ethanol (3.27%) Detection of phenolic compounds with HPLC-PDA Antibacterial activity against gram positive bacteria. Relation between phenolic compounds amount and antibacterial activity. [21, 24]
Propolis Meiganga (2006) Methanol (3.7%) lup-20(29)-en-3-one, lupeol, erythrodiol palmitate, 18-iso-olean-12-ene-3,11-dione, Caffeic acid phenethyl ester (CAPE) Antinociceptive activity of all the three pentacyclic triterpenoids in the test models of chemical nociception and mechanical hypernociception [26]
Propolis Meiganga (2008) Hexane (44.8%) Alkaloids, Coumarins, Steroids, Triterpenes, Volatile, 2 compound was not yet elucidated Absence of antibacterial activity [27]
Propolis Meiganga (2008) Methanol (3.5%) Alkaloids, Reducing compounds, Coumarins, Flavonoids, Saponins, Tannins Antibacterial activities; It was active against Escherichia coli and Pseudomonas aeruginosa (MIC: 0.2 mg/ml) [27]
Propolis Adamawa (2013) Acetone and methanol (70%) Terpenoids, phenolic acids, ursolic acid, β-amyrin, Prenylated phloroglucinone, cycloartenol acetate Phlorogucinonone was found to possess the highest potency against Trypanosoma brucei brucei [52]
Propolis Adamawa (2007) Ethanol (missing data) Missing data Among all African propolis sample tested, Cameroonian propolis was the most potent. [25]
Propolis Ngaoundal (2011) Ethanol (5.25%), methanol (9%) and water (1.5%) Volatile oils, Phenolic compounds, Saponins, Reducing substances, Coumarines, Flavonoids, Triterpenes, Catechic tannins, Fatty acids. All extracts contain phenolic compounds and present antiradical activities Antioxidant capacities: the order of decreasing antiradical activity is Water > Methanol > Ethanol [26]
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 [23]
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. [23]
Meiganga (2005)
Ethanol (4%) Contains phenolic compounds Antibacterial activity against gram positive bacterial strain tested except Enterococcus faecalis [21]
Martap (2005)
Ethanol (3.5%) 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. [21]
