Phyllanthus emblica
Uttar Pradesh, Tamil Nadu and Madhya Pradesh are the major amla producing states in India and it is generally harvested from January and February. Amla belonging to Phyllanthaceae family contains phenolic acids had it has high concentration of vitamin C which known to be very powerful antioxidant, it protects against LPO by acting as a scavenger of ROS. Ellagic acid a polyphenol has been reported to show antiproliferative activity by reduces cancer cell viability by increasing caspase-3 activity. Chebulinic acid an ellagitannin has been reported to show antiproliferative activity by inhibiting breast cancer metastasis and promotes cell death through down regulation of SOD1 and induction of autophagy. |
