Determination of Oil Quality and Antifungal Effect of Selected Citronella Accessions (Cymbopogon nardus, Cymbopogon winterianus) to Formulate an Anti-Dandruff Shampoo

Abstract

Citronella is an aromatic grass of the family Poaceae which can be classified into two categories Ceylon Citronella (Cymbopogon nardus) and Java Citronella (Cymbopogon winterianus). The Citronella oil was extracted from five selected Ceylon Citronella (HP T1, HP T2 and HP T3) and Java Citronella (MP T1 and MP T2) accessions using steam distillation and hydrodistillation methods. Citronella oil quantity extracted by hydrodistillation with Xylene from Ceylon Citronella was higher (2.45-2.67 mL/100 g) than the Java Citronella (1.57-1.64 mL/100 g). The oil quantity of Ceylon Citronella (HP T1-5.52 %, HP T2- 1.40 %, HP T3- 1.05 %) and the quantity of Java Citronella (MP T1- 1.25%, MP T2- 1.79%) extracted by hydrodistillation showed a significant difference (P100 mL), dirt dispersion (no ink in foam), viscosity, low wetting time and solid content (HP T3-14.750.12%; MP T2-12.330.19%) in acceptable specification range. This study exhibits that Ceylon Citronella oil HP T1 has the highest oil quantity from all selected accessions. Hydrodistillation can be used to extract high oil quantity than the steam distillation method from both Java and Ceylon Citronella types. Compared to Ceylon Citronella oil, Java oil has significant potential industrial applications with high Geraniol content and with the highest antifungal activity against C. albicans. Also, the tested Citronella oil of all selected accessions of both Java and Ceylon types meet the organoleptic and physiochemical requirements specified by the ISO and SLS quality standards with excellent antifungal activity against C. albicans, which provides prospective to use Citronella oil as a natural, safe, and eco-friendly fungicide in future product formulations.
