Etlingera maingayi is a species of flowering plant in the Zingiberaceae family.[2] It is also known as Malay rose,[3] is a species of herbaceous perennial plant[citation needed] of the family Zingiberaceae. This species occurs in southern Thailand, where its flowers are eaten as vegetables, and Malaysia.[4]
Description
Etlingera maingayi grows to less than 2 m (6 ft 7 in) high.[5] Its leaves are variable, with undulating fringes, and emit a sour scent when crushed.[6] Young leaves are translucent and reddish on both sides.[4]
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.[6] 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.
