The results obtained from qualitative analysis of phytochemical compounds among all extracts are shown in Table 3. The total phenolic content (TPC) which experiences a steady increase in both leaves and stem extracts ranges from 0.000221 to 0.000902 mg/g. Meanwhile, the total flavonoid content ranged from 0.000202 to 0.000905 mg/g. In contrast to phenolic compounds, the total flavonoid content (TFC) in leaves and stems shows different responses as the extraction time increases. TFC in the leaf extracts fluctuates over time while a slight drop is observed in the stem extracts. These results are in line with some previous works on the topic, which reported that alteration on phytochemical compound happens throughout the plant organs. A study on phytochemical compound of Momordica charantia (Malik, 2019) revealed that the occurrence of some bioactive compounds differs in each extraction time intervals. Similar results were also found by Fajfri (2021), Permatasari (2020), and Dewi (2022...
