Etlingera maingayi, the Malay rose, is a species of herbaceous, perennial, flowering plant in the ginger family, Zingiberaceae.[2][3][4] This species occurs in southern Thailand, where its flowers are eaten as vegetables, and Malaysia.[5] It grows along forest edges and in disturbed areas.[4]
Description[edit]
Etlingera maingayi grows to less than 2 m (6 ft 7 in) high.[6] Its leaves are variable, with undulating fringes, and emit a sour scent when crushed.[7] Young leaves are translucent and reddish on both sides.[5]
Chemistry[edit]
Leaves of E. maingayi displayed ferrous ion chelating ability and lipid peroxidation inhibition activity that were much higher than young leaves of Camellia sinensis.[7] 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.
