        abstract = {Potential of secondary metabolism (production, persistence and effectiveness) of an organism has diversity that is commonly caused by genetic or environmental factors. The diversity of secondary metabolites potential can be occur because of differences in population, life cycle, time of cultivation, soil, climate, and geographic condition. In the process of cultivation, to obtain effective secondary metabolite compounds, it must be supported by appropriate habitat. The aim of this study was to determine the content of phenolic compounds in Pluchea indica from some altitude habitats. This study was a descriptive research. P.indica leaves samples was obtained from Bangkalan for lowland (28.3-31,72 m asl), Dlundung - Trawas for middle-altitude land (727-937 m asl), and in Coban Talun ? Batu for highland (1303-1322 m asl). Simplicia of P.indica leaves was macerated and extracted by dissolving in methanol, ethyl acetate, distilled water, and n?butanol. Total polyphenol (gallic acid/GAE) contents was determined using UV - VIS spectrophotometer. Result of the study showed that content of phenolic compounds (gallic acid) on P. indica in Bangkalan/lowland (0.441 mg/g) was higher than P. indica growing in Trawas/middle-altitude land (0.364 mg/g) and in Batu/highland (0.303 mg/g). Phenolic compound characteristic was mostly semi-polar which was indicated by the largest total phenol in ethyl acetate fraction (0.412mg/g bk).}
