Abstract

Phytochemical study on the roots of Croton argyratus (Euphorbiaceae) has been carried out. Isolation and purification of the methanolic extract afforded a styryldehydropyrone, (+)-goniothalamin and a clerodane-type diterpene, (-)-junceic acid. The structures of these compounds were determined by spectroscopy methods such as mass spectrometry (MS), 1H and 13C NMR and by comparison with those of previously reported data. This paper report s the isolation and elucidation of theabove compounds.

Kajian fitokimia telah dilakukan ke atas akar Croton argyratus (Euphorbiaceae). Isolasi yang dilakukan ke atas ekstrak metanol spesies ini telah berjaya memencilkan dua sebatian iaitu (+)-goniothalamin (sebatian stirildehidropairon) dan (-)- asid junsik (sebatian diterpena jenis klerodan). Elusidasi struktur sebatian-sebatian ini ditentukan menggunakan kaedah spektroskopi seperti spektrometri jisim (SJ), resonan magnet nukleas (RMN) 1H dan 13C dan juga perbandingan dengan literatur. Kertaskerja ini membincangkan tentang pemencilan dan penentuan struktur bagi sebatian-sebatian di atas.
