Alkaloids from Pulai (Alstonia scholaris (L.) R. Br.) leaves of Lombok Island on the basis of GC-MS analysis

Alstonia scholaris R. Br., (Apocynaceae) is widely distributed in Indonesia and in Lombok Island, the plant locally known as ";lolon nita"; has been used to treat malaria. To locate potential bioactive compounds, acid-base extraction was carried out. From the base fraction, two new indole alkaloids with diastomeric structure, named Mataranine A and B, were isolated. The structures of the two alkaloids were elucidated on the basis of UV, NMR and mass spectral data. Keywords: alkaloids, Alstonia scholaris, Lombok, mataranine

Lombok Island

Buah Makasar [Brucea javanica (L) Merr] is one of the local plants in Lombok Island that is traditionally used for diabetic medication. The purpose of this research was to identify the chemical constituents containing in methanol leaves and seed extract of Buah Makasar. The methods used were phytochemical screening for some groups of chemical compounds and GC-MS analysis. The result of phytochemical screening showed that methanol extract of B. javanica seed contains alkaloids, terpenoids, and tannin with a high intensity; while the leaves extract contains alkaloids, flavonoids, steroids, tannin, and saponin. The differences of chemical compositions in the leaves and seed extract may give them have different bioactivities. GC-MS analysis showed some fatty acids containing in the seed extract such as stearic acid and palmitic acid.
