<b>Background and Objective:</b> The cat whiskers plant (<i>Orthosiphon aristatus</i> Blume Miq) is a plant that has been widely used as raw material for traditional medicine. The population of white-purple varieties of <i>O. aristatus</i> is decreasing efforts to maintain the white-purple <i>O. aristatus</i> need to be done keeping in mind its potential as raw material for traditional medicine. This study aims to determine the composition of a suitable medium in growing plantlet <i>O. aristatus</i> white-purple varieties and the content of its secondary metabolites. <b>Materials and Methods:</b> The internode explants were induced on MS medium added by various combinations of zeatin and 2,4-Dichlorophenoxyacetic acid (2,4-D). Root induction was carried out on shoots formed on MS medium with Indole-3-Butyric Acid (IBA). The acclimatization process was carried out using soil media. Determination of secondary metabolite levels was carried out on <i>O. aristatus</i> (<i>in vitro</i> culture) and wild-type plants aged ten months using high-performance liquid chromatography (HPLC). <b>Results:</b> MS+BAP 2ppm+NAA3 ppm media was the optimal medium for growing shoots in leaf explants. Media MS+zeatin 3 ppm+2,4-D 2 ppm produced good shoot growth on internode explants. The best root induction occurred in MS+IBA media of 0.75 ppm. The acclimatization process was successful on shoots originating from the internode, while those from leaf explants had not succeeded in growing and developing. <b>Conclusion:</b> The levels of rosmarinic acid and sinensetin in the white-purple variety <i>O. aristatus</i> (<i>in vitro</i> culture) were 1.08 and 1.62% w/w and higher than those of wild varieties.
