This study aims to determine the phytochemical composition and antioxidant activity of air-dried Cordia dichotoma seeds. Total polyphenolic content was analyzed via the Folin-Ciocalteu method. Total triterpenoid content and amino acids was analyzed colorimetrically. The rosmarinic acid content was examined using high-performance liquid chromatography tandem mass spectrometry. The ethanolic extracts contained polyphenolic compounds (1.0%), triterpenoids (0.075%), amino acids (1.39%), and rosmarinic acid (0.0028%). The results from this study indicate that C. dichotoma seeds are a rich source of polyphenolic compounds and amino acids, which can be used for quality assessment. The ethanolic extract of C. dichotoma seeds has good antioxidant capacity.
