The increasing number of population causes increasing food needs too. The market is one place where food needs are available. One of the plants that has economic value and can be used is jonggol (Erechtites valerianifolia Wolf.). The objective of this study is to determine the morphology, forms of use and chemical compounds found in the jonggol plant. This research was conducted on October 2017 until March 2018. The methods used in this study were preliminary surveys, market area selection, morphological observations, interviews, chemical compound detection, and data analysis. The selection of market areas was carried out in 5 sub-districts of Malang City, with each sub-district selected by one market, they are Sawojajar Market, Sukun Market, Malang Big Market, Blimbing Market, and Dinoyo Market. The results of the study show that jonggol is a herbaceous plant. Jonggol has a taproot type with a hairy and grooved stem surface. The jonggol leaves are obovate, pointed ends, tapered base with a leaf surface with adaxial and abaxial hair. The flowers are cup-shaped compound flowers and they are located at the end of the stem. The petals are modified into pappus. The crown is reddish yellow, the pistil head is brownish red, and the stamens are purple. The fruit type is achene which is brown. Jonggol has a UVs value of 3.0 meaning that it is an important species or priority species, this is due to Jonggol plants often used as vegetables.
