Abstract

C. asiatica cultivated using five types of composts namely (1) compost A; (2) compost B; (3) compost C; (4) commercial Biomart ; (5) control were extracted and asiaticoside content in the crude extract was analyzed. The highest crude extract yield was control with percentage yield of 42.80%. The identification and quantification analysis of asiaticoside was carried out using RP-HPLC. The RP-HPLC analysis of standard asiaticoside showed the retention time ranged from 9.798 min to 9.806 min. The asiaticoside content in the sample ranged from 3.57 mg/g to 10.55 mg/g, in which the samples cultivated using commercial biosmart had the highest content while the sample cultivated using compost A had the lowest content This method can be used to investigate the asiaticoside content in various sample of C. asiatica. The asiaticoside content has significant moderate correlation with the type of compost used (r= 0.692, p<0.05). This has led to a better way for C. asiatca cultivation to enrich the asiaticoside content for pharmaceutical uses.
