INTRODUCTION: Tamarind or Tamarindus indica
L. is widely growth in tropical regions including
Thailand and has long been supplied as an
important nutrition source and traditional
medications1). In Thailand, the flower, fruit and
leaf are consumed as food materials of which
there are two species commonly cultivated
particularly the sweet Tamarind2) which has been
developed in several cultivars that bring variety of
tastes and accounted as one of an economic
plant. There were several attempts searching for
possible potential utilization of Tamarind seed
which is waste from the consumption. Biological
activity assessment of Tamarind seed was
reported on the radical scavenging1), lipid
peroxidation reducing3) and anti-microbial
activities4) including anti-inflammatory potential5).
However, the reported preparation methods are
complicated and relied on advanced techniques.
Therefore, development of the ease and
practical extraction was conducted. The
antioxidant activity of each extract was evaluated
with the assessment of total phenolics content to
relate the active principle compound with
biological activity. Furthermore, applications of
Tamarind seed coat extract based on antioxidant
activity appropriate for anti-wrinkle cosmetics
were performed.
