Studies
• R&D on seed gum for a pharmaceutical substitute for the imported guar gum used as a binder in tablet formulation. In 1996, ipil-ipil was found to be an excellent liquid excipient as a suspending and thickening agent.
• Inhibition of Growth of Hair by Mimosine: Loss of hair been reported in animals following ingesting of seeds and foliage and in women after consumption of LG seeds. The toxic principle is leucenol, an amino-acid (identical to the mimosine of Mimosa pudica) found primarily in the seeds of ipil-ipil, and in lesser amounts in foliage and stems.
• Study of enhancement of sensitivity of hepatoma and lung cancer cells to chemotherapeutc drugs by mimosine from seeds of Leucaena Glauca Benth.
