This protocol developed a method to estimate the yield of compounds on the TLC plate using the blue-LED illumination technique. The advantages of this method are that the blue-LED illumination technique is a safe, effective and cheap method, and allows the researcher to measure multiple samples at the same time. This method also can be applied to biochemistry and natural products chemistry.

To begin, dry the culture at 40 degrees Celsius for 24 hours. Transfer the dried culture into a 50 milliliter tube using sterilized tweezers and add 15 milliliters of ethyl acetate. Shake the mixture vigorously by vortexing for one minute and incubate the tube for one hour at 40 degrees Celsius with shaking at 200 RPM.
