Description
E. maingayi grows to less than 2 m (6 ft 7 in) high. Its leaves are variable, with undulating fringes, and emit a sour scent when crushed. Young leaves are translucent and reddish on both sides.
Chemistry
Leaves of E. maingayi displayed ferrous ion chelating ability and lipid peroxidation inhibition activity that were much higher than young leaves of Camellia sinensis. Leaves of E. maingayi had the highest yield of oil (1320 mg/100 g) consisting mainly of lauric acid (45%) and decanoic acid (43%). The unpleasant sour scent of leaves when crushed may be due to these two acids.
