Malus domestica
Apple is grown predominantly in Jammu and Kashmir, Himachal Pradesh, and the hills of Uttar Pradesh. They are typically harvested between September and October. India is the fifth largest apple grower, with about 2.5 million tonnes produced in 2020. Apple, a member of the Rosaceae family, is rich in secondary metabolites such as phenolics, flavonoids, and anthocyanins. Apple contains a variety of bioactive compounds, including quercetin, phloretin, and chlorogenic acid. These bioactive substances have been reported to have significant immunomodulatory action. Quercetin, a flavonoid, has been reported to have anti-inflammatory effect by decreasing LPS-induced tumour necrosis factor (TNF-α) production in macrophages. Phloretin has been reported to have antiproliferative effect in human hepatoma (Hep G2) cells by inhibiting type 2 glucose transporter (GLUT2), while chlorogenic acid, a phenolic acid, has been reported to have antiproliferative activity in cancer cells by lowering cell proliferation. |
