Digunakan untuk pereaksi penyemprot pada lempeng KLT Kromatografi Lapis Tipis dimana akan memberikan hasil dengan noda ungu-biru sampai coklat merah. Reaksi utama yang alkaolid biosintesis senyawa alkaloid adalah reaksi mannich antara suatu aldehida dan suatu amina primer dan sekunder, dan suatu senyawa enol atau fenol. Hingga kini belum ada pendefinisian tunggal dan penggolongan yang jelas dari alkaloid.

Molecular Plant ; 3 1: In their formation there are 43 enzymes grouped into oxidoreductases, transferases and lyases, which in some cases represent atypical examples of the manner in which the secondary metabolism diversification was originated. Berdasarkan hal tersebut, maka alkaloida dapat dibedakan atas tiga jenis utama, yaitu: Selain daun-daunan, senyawa alkaloid dapat ditemukan pada akar, biji, ranting, dan kulit kayu.
