Resumen
Protocols for quantification of polyphenols as total phenols and for their separation on thin layer chromatography (TLC) were optimized. The total phenol contents generally differ for the different strains of Carabao (Batangas, Bulacan, Davao, Guimaras, Nueva Ecija, Pampanga and Zambales [Philippines], ranging from 95 mg catechin /g dried sample or catechin equivalents (CE) to 440 CE for the Davao and Batangas strains, respectively. Generally, no significant differences was observed in the total phenol contents of samples belonging to the same strain even if the samples came from different locations. However, variations in the total phenol contents of samples of Batangas strain harvested at different seasons was observed. TLC of phenolic extracts of the young leaves of various mango samples on silica gel plates resulted in separation of 9-14 bands under UV 254 and 12-16 bands under UV 366. Using samples coming from the same location and harvested at the same time (termed as control), each strain had a characteristic banding pattern even if the unstable bands observed were not included. However, when leaf samples were obtained from different sites or at different times, in general, their phenolic banding patterns were different from control. Thus, it may not be possible to use phenolic banding patterns of leaf samples as markers for the different strains because of effects of location and season
