Abstract

Burahol (Stelechocarpus burahol (Blume) Hook & Thomson) is one of fruit tree that originally was founded in Indonesia. Traditionally burahol is used as natural deodorance, but due to low economic value, the cultivation program of this plant species is almost abandoned. Regarding to this situation, currently this plant species could be categorized as one of endangered species. At present, economic value of this fruit is almost neglected and this is the main reason why not many people interested to cultivate this plant. In order to change the people opinion on this plant and to improve it economic value, study on the chemical content of this plant had been carried out. From the research work, it was founded that burahol fruit have a significant content of anti-oxidative compound. From the anti-oxidative analysis using DPPH (1,1-diphinil pycril hidrazil) method, the lowest IC50 was showed by n-buthanol extract of flower (22.44 ppm) and ethyl acetate extract of fruit (29.12 ppm). Flower part also showed low IC50 of ethyl acetate extract (35.07 ppm). Further purification through fractionation process of the plant extract was surprisingly followed by the decrease of anti-oxidative activity. © 2006 Jurusan Biologi FMIPA UNS SurakartaKey words: anti-oxidative, 1,1-diphinil pycril hidrazil , burahol.

Abstract

Kedawung (Parkia roxburgii G. Don.) is one of plants that originally could be found in almost all parts of Java Island. Due to lack of attention, at present situation this plant could be categorized as an endangered species. This plant species distributed widely in Africa. In several African countries, this plant has an important position either as food resource or alternative medicine. In Indonesia, traditionally kedawung tree often use as medicine, especially as part of “jamu gendong” formulation. This work was focused on the study of phytosterol content and it distribution. The research result show that almost all parts of kedawung tree have a significant content of phytosterol, which is dominated by beta-sitosterol. The highest beta-sitosterol content was founded in the stem of leaf (35.24% (w/w) and pod (29.67% (w/w). © 2006 Jurusan Biologi FMIPA UNS SurakartaKey words: endangered plant species, phytosterol, beta-sitosterol, traditional medicine.
