There is a long history to the use of Rubus plants in China as wild berry and medicinal plants and so on. According to the investigations and studies on horticultural purpose, 23 species and 4 varieties are considered as excellent germplasm for selection and breeding of raspberry and blackberry. Some species with high fruit quality and vast reserves can be used directly for fresh market or processing. 45 species and 4 varieties are used as medicinal plants for more than 40 diseases. Investigation of the physical and chemical properties, stabilities and components of the pigments extracted from the fruits of some species reveals that the pigments in bramble fruit can be extracted more readily with alcohol than with water. Their anthocyanidins including cyanidin, pelargonidin, delphinidin as well as their glycosides are the principal pigments in the fruits of bramble. Some flavonoids exist in bramble fruits also. R. tephrodes Hance and R. lambertianus Ser. are considered good natural resources of edible pigments because of the good color and stability.
