Plus the lack of selectively of the hexane and chloroform solvents for phenolic compounds present in red propolis, which present an semi-polar nature such as methoxylated isoflavonoids (formononetin) and prenylated phenolic compound (guttiferone) (Table 4) and xanthones (Table 2) besides of phlobaphene tannins (Table 2) in all samples detected in phytochemical prospection.
The in-vivo anti-oxidant property of C. sieberiana root bark extract demonstrated in this study may be due to the presence of flavonol/flavonoid/flavone or related compounds with polyhydroxy and/or phenolic groups which we had earlier detected by phytochemical analysis [ 9].
The dried powdered LP extract was sent to Forest Research Institute Malaysia (FRIM) for phytochemical screening to detect the phytochemical constituents.
There have been 10,038 phytochemicals detected in cranberry metabolomics profiles [ 6].
It appears that a number of possible phytochemicals detected in F-10 could contribute to the anti-MRSA activity.
The antiarthritic effect of fractions (EAPA and BPA) of hydroalcoholic extract of P. alba could be due to the presence of flavonoids, alkaloids, terpenoids, glycosides, saponins, tannins, and steroids detected after preliminary phytochemical screening of the fractions.
These results indicated that the flavonoid C-glycoside (hydrophilic flavonoid) and the other hydrophilic components detected by the phytochemical screening (alkaloid and tannin (data not shown)) also play a role in the observed antiulcerogenic activity.
It is also noteworthy to highlight on the inconsistency with regards to the presence of low amount of flavonoids in MEDL as detected in the phytochemical screening and the high TPC value of MEDL, and to provide possible explanation for this inconsistency.
Same phytochemicals were detected in D. grandiflora extracts reported in a different study that demonstrated anti-staphylococcal activities [ 15].
The flavonoids in alcoholic extract were detected by TLC and phytochemical analysis [ 88].
