Variation of eurycomanone content within and among populations of E. apiculata A.W. Benn.

Abstract

Abstract Information on the eurycomanone content of E. apiculata A.W. Benn from natural populations in Indonesia is unknown. This study aimed to assess the variation of eurycomanone content within and among populations of E. apiculata, determine the correlation of eurycomanone content with environmental factors, and determine the collection sites of genetic material for the establishment of the breeding base population of E. apiculata. The analysis of eurycomanone content was carried out using High-Performance Liquid Chromatography. This study found that the highest eurycomanone content was observed in the Rumbio population (9.86 mg/g) and the lower value was observed in the Pokomo population (4.44 mg/g). The average variation of eurycomanone content within the population was 25.72%. The coefficient of eurycomanone differentiation among populations was 84.33%, indicating that the variation of eurycomanone content among populations of E. apiculata was higher than the variation of eurycomanone content within-population (15.67%). Pearson correlation of eurycomanone content with population environmental factors showed no significant correlation. Based on the eurycomanone content and clustering, the Rumbio population can be selected as a source of the genetic material of E. apiculata for eurycomanone production via the breeding program in the future.
