When the bacteria metabolizecitrate, the ammonium salts are brokendown to ammonia, which increases alkalinity. Mandelin is particularly useful for testing molly samples, because its able to detect a potential deadly adulterant that is now rarely(thankfully) sold as MDMA. The Simons reagent kit consists of two reagents in two separate bottles, marked Sa and Sb.

Amphetamine Reagent Test Kit. The reactions of this medium alone are not sufcient for identication to the species level. If the sample consists of MDA, 5-APB, 6-APB, it won't change color. Shake for 3 minutes and incubate in the dark at room temperature for 24 hours. Do you have other reagents apart from simons and marquis? Simons should indeed not react to MDA, so that discoloration will be because of impurities. Always test under a strong light and using the smallest possible sample. Simmons later modified this formulation to produce a solid medium that eliminated potential errors when interpreting growth. doi:10.1371/journal.pone.0069609.
