Introduction: C. albicans is a normal flora in oral cavity that can be pathogenic that
causing oral candidiasis. Curcuma xanthorrhiza ethanoic extract has a main
component, xanthorrhizol that was reported to be able to inhibit and eradicate C.
albicans biofilms at a 15% concentration and reduce the activity of phospholipase and
proteinase enzymes of C. albicans. Furthermore, curcuma xanthorrhiza ethanoic extract
is formulated and developed into microemulsion oromucosal drops. In the development
of the drug, it is necessary to determine the formulation and test the stability in
biological, physical, and chemical. Objective: Determining the formulation and
evaluating the physical and chemical stability of microemulsion oromucosal drops
containing 15% curcuma xanthorrhiza ethanoic extract. Methods: Curcuma
xanthorrhiza ethanoic extract is formulated into microemulsion oromucosal drops
containing 15% curcuma xanthorrhiza ethanoic extract. Then, the physical and
chemical stability are evaluated for 2-4 weeks in 3 different temperature, that is 4 ±
2oC; 28 ± 2oC; and 40 ± 2oC. Furthermore, the physical stability in the form of
organoleptic, homogeneity, pH, viscosity, and flowing type are evaluated. Chemical
stability is evaluated the xanthorrhizol level using the GC-MS method. Results:
Microemulsio oromucosal drops containing 15% curcuma xanthorrhiza ethanoic
extract have organoleptic; brownish-yellow solution, bitter taste, and smells like herb,
homogeneity; there is a separation between the oil and water phase, pH ranges from
6,3-6,9, and flowing type are pseudoplastic. The viscosity value decreases with the
increasing of storage temperature. Xanthorrhizol level are decreasing after 2-4 weeks
of storage in the 3 different temperature. Conclusion: The separation between the oil

"Background: One of the major challenges in developing an antifungal against Candida albicans as a therapeutic strategy for oral candidiasis is its resistance towards antimicrobial agents. Currently, medicinal plants are continuously being developed as a therapeutic agent, including Javanese turmeric (Curcuma xanthorrhiza Roxb.), an Indonesian plant widely used as a traditional medicine. Its main active compound, xanthorrhizol, as well as the Javanese turmeric Ethanol Extract (EET) had been reported to have antifungal properties. However, extract quality as well as cultivation site of a medicinal plant may affect its’ effectivity as a therapeutic agent. Objective: To analyze the influence of Javanese turmeric cultivation site against its’ ethanolic extract effectivity in inhibiting C. albicans biofilms. Methods: 2 Javanese turmeric ethanolic extract were collected from different cultivation sites, which were Bogor, West Java and Malang, East Java. The extracts were tested for inhibitory activity against C. albicans biofilm using OD600, TPC, and MTT assay measurements. Results: There were concentration differences of xanthorrhizol content in between the two extracts. Despite so, both extracts showed insignificant MBIC50 differences at roughly 0,10 µg/mL, while their MBIC90 were measured to be constant at all biofilm development phases, at 0,30 µg/mL. Conclusion: The different cultivation site of Javanese turmeric in Java island does not influence the effectivity of JtET in inhibiting C. albicans biofilm.
