WebBrucine is used in analytical chemistry for separating racemic mixtures (Merck Index, 1989). It has been patented as additive for lubricants (Merck Index, 1984). Brucine may be a constituent of suntan preparations (Arena, 1986). Agriculture - Brucine and the other alkaloids obtained from the seeds of Strychnos have been used for destroying ... Brucite is the mineral form of magnesium hydroxide, with the chemical formula Mg(OH)2. It is a common alteration product of periclase in marble; a low-temperature hydrothermal vein mineral in metamorphosed limestones and chlorite schists; and formed during serpentinization of dunites. Brucite is often found in association with serpentine, calcite, aragonite, dolomite, magnesite, hydromagnesite, artinite,
