Abstract：
Plant dyes have the advantages of green environmental protection and high safety, but due to the shortage of resources, high cost and low color fastness, the industrial application of plant dyes is limited. Baiyi people have the traditional custom of plant dyeing in Heqing, Yunnan Province, and there are rich local dye plant resources and traditional dyeing technology. In order to investigate, and study Baiyi people plant dyeing and related traditional knowledge, meanwhile aim to expand plant dye resources and promote the development and utilization of plant dyes, we conducted ethnobotanical investigation on plant dyeing and related traditional knowledge of Baiyi people in Liuhe Yi nationality Township, Heqing County, Dali Prefecture. From September 2019 to March 2020, 288 reporters of information were interviewed by semi-structured interviews in Dali prefecture heqing county liuhe yi township of four villages; local dye plants were investigated by field research; traditional plant dyeing crafts were recorded by participatory observation; traditional knowledge of plant dyeing was analysed through quantitative analysis (f value, CIIs value, ICF value). The results were as follows: (1) The Baiyi people use 11 species of dye plants in Heqing, belonging to 10 families and 11 genera; (2) People of different region, age, gender, the cognition of traditional knowledge of plant dyeing is different; (3) The use frequency and cultural importance index of Viburnum cylindricumBuch.-Ham. ex D. Don and Buddleja officinalis Maxim. are higher, and the cognition of Baiyi people was highly consistent on dye plants of blue; (4) Moreover Baiyi people often use dye plants to dye their own traditional cloth (folk cloth made from Gerbera delavayi). This research reveals that Baiyi people have a relatively complete knowledge system of traditional plant dyeing in Heqing, but it is gradually lost with the development of the times. This study provides scientific clues for the exploitation of dye plant resources and the research of traditional plant dyeing technology, promotes the industrial application of dye plants of minority. It has a great significance and application value for the economic development in minority areas.

Abstract：
Prinsepia utilis is a perennial deciduous shrub of an edible medicine in the ethnic communities of Northwest Yunnan. It is widely applied in traditional culture, medicine and food in that area. With the development of modern society, P. utilis and its related traditional knowledge face the danger of disappearing. The purpose of this study was to explore the protection and inheritance of resources and related traditional knowledge of P. utilis in native area. Based on ethnobotanical field investigation, the substance basis of the main traditional functions of P. utilis and skin-care activities were preliminarily studied by using the methods of chemical and pharmacological activity testing of natural drugs. The results were as follows: (1) P. utilis is widely used for fencing protection, wind prevention, soil fixation, the treatment of skin injury, food and other traditional usages in ethnic communities of Northwest Yunnan; (2) Ten individual compounds with skin care activities were detected from the extracts of different parts of P. utilis, such as gallic acid, quercetin; (3) The total flavonoid content of the extracts from the leaves of P. utilis was higher than that of the fermentation products and the extracts from the fruit of P. utilis.(4) The fruit oil of P. utilis with the highest frequency of traditional utilization showed great DPPH radical scavenging activity, and the antioxidant activity was different among different producing areas and processes. The results of this study preliminarily confirmed the correlation between the substence basis and the related activities of the traditional skin care efficacy of P. utilis, and provided a preliminary application basic research for the further research and development of the protection and traditional inheritance of resources and related traditional knowledge of P. utilis.
