"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.

Background: One of the major challenges in developing an antifungal against Candida albicans as a therapeutic strategy for oral candidiasis, an opportunistic oral fungal infection, is its resistance towards antimicrobial agents. Currently, medicinal plants are 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, is known to have antifungal properties. However, extract quality as well as cultivation site of a medicinal plant may affect its’ effectivity as a therapeutic agent. Up until now, there hasn’t been any datas that explain how these factors affect Javanese turmeric ethanolic extract as a C. albicans strategy. Objective: To analyze the effect of Javanese turmeric cultivation site against its’ ethanolic extract ability to inhibit 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 between the extracts. Despite so, both extracts’ MBIC50 differences were insignificant 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: There were no significant differences between the MBICs of both extracts against C. albicans biofilm. More research needs to be done to confirm the role of other factors such as storage time on their MBIC."

"Latar belakang: Temulawak adalah tanaman obat asli Indonesia yang mengandung zat aktif xanthorrhizol dan memiliki efek antifungal. Dengan membentuk biofilm, Candida albicans menjadi virulen dan semakin virulen ketika mencapai fase maturasi. Tujuan: Mengetahui potensi ekstrak etanol temulawak dalam menghambat biofilm C. albicans isolat klinis dan C. albicans ATCC 10231 pada fase maturasi. Metode: Pemaparan ekstrak etanol temulawak berbagai konsentrasi pada biofilm C. albicans dimulai pada 1.5 jam setelah inkubasi dan dilanjutkan selama 48 jam. MTT assay digunakan untuk mengukur persentase viabilitas sel C. albicans pada biofilm yang kemudian dikonversi menjadi persentase inhibisi biofilm oleh ekstrak temulawak. Hasil: Terhadap C. albicans isolat klinis, Kadar Hambat Minimum KHM dan Kadar Bunuh Minimum KBM ekstrak etanol temulawak adalah 15 dan 30, sedangkan terhadap C. albicans ATCC 10231 adalah 20 dan 35. Nilai Kadar Hambat Biofilm Minimum KHBM50 ekstrak etanol temulawak adalah 35 terhadap C. albican isolat klinis dan 40 terhadap C. albicans ATCC 10231. Dibutuhkan konsentrasi ekstrak etanol temulawak yang lebih tinggi untuk menghambat C. albicans ATCC 10231 daripada untuk menghambat C. albicans isolat klinis. Kesimpulan: Baik terhadap C. albicans isolat klinis maupun C. albicans ATCC 10231, ekstrak etanol temulawak berpotensi menghambat biofilm C. albicans fase maturasi.

"Latar Belakang: Ekstrak etanol temulawak (Curcuma xanthorrhiza Roxb.) telah terbukti secara in vitro memiliki khasiat sebagai anti Candida albicans (C.albicans). Dalam upaya pengembangan tanaman obat tersebut sebagai obat herbal terstandar anti C.albicans, ekstrak etanol temulawak telah diformulasikan menjadi obat tetes oromukosa. Temulawak mengandung kurkumin yang merupakan senyawa polifenolik berwarna kuning yang dapat menyebabkan diskolorasi gigi. Tujuan: Mengetahui pengaruh paparan obat tetes ekstrak etanol temulawak terhadap warna email gigi. Metode: Gigi premolar tanpa karies dan defek struktural dicelupkan dalam obat tetes ekstrak etanol temulawak, CHX 0,2%, dan akuades selama 1 menit kemudian dibilas dan direndam dalam akuades selama 10 menit pada suhu 37oC. Tahapan dilakukan sebanyak 42 siklus (simulasi penggunaan 2 minggu) dan 63 siklus (simulasi penggunaan 3 minggu). Analisis warna dilakukan menggunakan colorimeter pada 3 tahap waktu yaitu sebelum paparan, setelah paparan, dan setelah penyikatan gigi. Nilai yang didapatkan berupa ΔE yang menunjukkan selisih nilai pengukuran warna email sebelum dan setelah paparan obat serta sebelum dan setelah penyikatan. Hasil: Pada tahap waktu T1-T3 simulasi penggunaan 2 minggu dan 3 minggu, nilai ΔE>3.3 pada ketiga kelompok sehingga terlihat adanya perubahan warna yang signifikan antara warna gigi awal dan setelah penyikatan gigi. Terdapat perubahan warna gigi yang signifikan setelah dilakukan penyikatan dengan pasta gigi. Kesimpulan: Obat tetes ekstrak etanol temulawak mengakibatkan perubahan warna email gigi yang signifikan. Penyikatan gigi dapat mengurangi efek perubahan warna pada email gigi.
