• Indonesia's tropical forest is widely used as a source of raw materials for traditional medicine. Pulai (Alstonia scholaris R.Br) is one of forest medicinal plants widely spread in the Indonesia forest to treat various diseases. Phytochemical compounds play an important role in the pharmacology effect depending on many factors such as age, geographical site, solvents, and extraction methods. This research aimed to investigate the phytochemical content of A. scholaris' bark from a different region in Indonesia and to study the effect of the maceration and reflux extraction method on the yield of crude extract. A. scholaris barks were extracted by maceration and reflux method to get the yield. Then they were tested for phytochemical content for alkaloids, flavonoids, tannins, steroid saponins, and triterpenoids. The results showed that pulai bark extracted by maceration was bigger in yield than that of the reflux method, as stated follows: Palembang, Cifor, Banjar Baru, and Ngebel, which were 5.2%, 7.92%, 3.35%, 4.19, respectively. The phytochemical test showed that all samples of positive flavonoids and alkaloids. A. scholaris' bark from Cifor-Bogor had the strongest flavonoids content of all, and it had potential activity as an antioxidant.
