Dermatophyllum secundiflorum Dermatophyllum secundiflorum Dermatophyllum secundiflorum is a species of flowering shrub or small tree in the pea family, Fabaceae, that is native to the southwestern United States (Texas, New Mexico) and Mexico (Chihuahua and Coahuila south to Hidalgo, Puebla and Querétaro). Common names include Texas mountain laurel, Texas mescalbean, frijolito, and frijolillo. Although "mescalbean" is among the plant's common appellations, it bears no relation to the "Agave" species used to make the spirit mezcal, nor to the peyote cactus ("Lophophora williamsii"), which contains the hallucinogenic alkaloid mescaline. It is well-adapted to arid and semi-arid habitats but is most common in riparian
Catechol Catechol Catechol ( or ), also known as pyrocatechol or 1,2-dihydroxybenzene, is an organic compound with the molecular formula CH(OH). It is the "ortho" isomer of the three isomeric benzenediols. This colorless compound occurs naturally in trace amounts. It was first discovered by destructive distillation of the plant extract catechin. About 20 million kg is now synthetically produced annually as a commodity organic chemical, mainly as a precursor to pesticides, flavors, and fragrances. Catechol occurs as feathery white crystals that are very rapidly soluble in water. Catechol was first isolated in 1839 by Edgar Hugo Emil Reinsch (1809 - 1884)
