Silbinol® is prepared from the dried heartwood of Pterocarpus marsupium (Indian Kino). It is standardized for 5%, 30% and 90% Pterostilbene. Pterostilbene, a structural analog of resveratrol, is more stable in vivo than resveratrol and has a comparable ability in improving the healthy glucose metabolism, reducing the oxidative radicals, and immune health improving ability. Thus, the product finds its application in managing blood sugar levels and improving the healthy immune interactions in the body.
Pterocarpus marsupium is commonly called as Malabar kino, Indian kino, or vijayasar. It is a medium to large, deciduous (which sheds leaves annually) tree that can grow up to height of about 30 m. The plant is native to India, Nepal, Taiwan, and Sri Lanka; in India it is commonly found in Western Ghats of the Karnataka-Kerala region and also in the forests of Central India.
Initiatives on sustainability
Pterocarpus marsupium is considered under the category of vulnerable to extinction species by World Conservation Monitoring Centre. The alarm has been sensed by Sami-Sabinsa Group and to act upon it has initiated a project to reforest Pterocarpus marsupium that resulted in planting about 166,600 saplings of the plant on 250 acres of land in Madhya Pradesh, a large and central Indian state. The group has committed to fund about $500,000 for this 10-year reforestation project, which it claims is the first initiative to conserve this high-value, multipurpose, threatened species in India. The project earned the Nutra-Ingredients-USA Editors Award for Industry Initiative of the Year for 2018.
