Zusammenfassung:	The pigmentation response, coloration components and the metal elemental content of Yunnan Red Pear were studied. Light is indispensable for peel pigmentation. With increasing duration of illumination of fruit, the area of skin colour and colour intensity of peel increases due to the accumulation of anthocyanin. The red anthocyanin component of Yunnan Red Pear skin is cyanidin-3-O-galactoside. Other phenolic compounds in pear skin are chlorogenic acid, isorhamnetin-3-O-galactoside and isorhamnetin-3-O-6"-malonylgalactoside; or isorhamnetin-3-O-6"-malonylglucoside; or isorhamnetin-3-O-malonylgalactoside. The elements Ca, Mg and Fe are abundant in Yunnan Red Pear flesh; Zn, Mn, Cu were also identified.
