I ran a TLC of methyl anthranilate and methyl salicylate and it came back with the supposed methyl salicylate spot with a larger Rf value than methyl anthranilate, indicating that it is supposedly less polar than the anthranilate. Just a recap, if you have on the end a Hydroxyl group, so OH. Born and raised in the city of London, Alexander Johnson studied biology and chemistry in college and went on to earn a PhD in biochemistry.
