Comparison of the Flavonoid Contents of Bajakah Plants from Tropical Forest in Kalimantan, Indonesia

Yudi Firmanul Arifin, Siti Hamidah, Gusti Muhammad Hatta


Kalimantan tropical forests have very high biodiversity wealth and are natural resources that need to be conserved and researched for human use. One type that is still a mystery for its benefits to humans is the type of liana, a type of climbing plant. These types have been used in local wisdom, namely one of the Bajakah types of plants as an anti-cancer. This research was conducted in two provinces in Kalimantan, Indonesia, namely Central Kalimantan in the tropical peat-swamp forest and South Kalimantan in the KHDTK ULM, a highland tropical forest. The content of flavonoids as antioxidants that act as anti-cancer for humans will be compared from each plant. The method used is a quantitative method, according to Robinson, 1995. The research goals are to find the Bajakah plant species with the highest flavonoid content and plant parts with the highest flavonoid content. The results showed that there were four species of Bajakah plants which local wisdom used by the community, namely yellow Bajakah (Jasminum elongatum (PJ Bergius) Wild.) and Balaran (Merremia peltata (L.) Merr) in highland tropical forests in South Kalimantan and yellow Bajakah (Fibraurea tinctoria Laur.) and red Bajakah (Uncaria acida (Hunter) Roxb) in the tropical peat-swamp forest in Central Kalimantan. The scientific novelty of research found that the content of each species and each part of the plant (stems, twigs, and leaves) contained flavonoids. In contrast, the highest content of flavonoids was found in red Bajakah leaves (Uncaria acida (Hunter) Roxb) from a topical peat-swamp forest in Central Kalimantan of 140.17 mg/ml, the highest of flavonoids in the stem is the species of yellow Bajakah (Jasminum elongatum (PJ Bergius) Wild.) from upland tropical forests in South Kalimantan at 83.00 mg/ml.


Keywords: Bajakah, flavonoids, stems, twigs, leaves.
