| Abstract: | This paper studied the chemical constituents from the leaves of Malus torangoades(Rehd.) Hughes growing in Tibetan regions. The compounds were isolated and purified by various kinds of column chromatography,such as the silica gel column,MPLC,semi-preparative HPLC,and Sephadex LH-20. The structures were elucidated by NMR spectroscopicmethods in combination with MS experiments. The results showed that 12 compounds were isolated from Malus torangoades(Rehd.) Hughes,and identified as phloridzin(1),phloretin(2),sieboldin(3),3-hydroxyphloretin(4),trilobatin(5),quercetin(6),quercitrin(7),isoquercitrin(8),rutin(9),hyperoside(10),coumaric acid(11),Caffeic acid(12). Compounds 1 ~ 5 are dihydrochalcones,6 ~ 10 are flavonoids,while 11 ~ 12 are phenolic compounds,of which compounds 3 ~ 5 and 7 ~ 12 were isolated from this plant for the first time. |
