Traditional markets play an important role in the exchange of plant resources and the preservation of traditional food knowledge. This study documents the diversity of food plants traded in Renmin Market, located in Youjiang District, Baise City, Guangxi, China, and evaluates their cultural importance using the Cultural Food Significance Index (CFSI). Field surveys were conducted through market observations and interviews with vendors and local informants. All edible plant species were recorded, including their scientific names, vernacular names, used parts, and modes of consumption. A total of 104 food plant taxa were documented, representing a wide range of plant families and growth forms. The recorded plants were used in four main utilization categories: vegetables, spices, fruits, and beverages. Frequently used plant parts included fruits, leaves, shoots, and underground organs such as roots, rhizomes, and tubers. The CFSI values showed considerable variation in cultural importance among species, ranging from 21.6 to 1764. The highest CFSI values were recorded for Cucurbita pepo, Allium cepa, Cucurbita maxima, and Houttuynia cordata, reflecting their frequent consumption and versatility in local cuisine. Comparative analysis with previous studies in Baise City indicated that 38 species were shared among three markets, while 30 species were recorded exclusively in Renmin Market. These findings highlight the diversity of food plants available in local markets and their importance in maintaining regional culinary traditions and plant-based dietary diversity.
