HPLC chromatogram of ginger oleoresin (A), of plasma from control subjects (B) and of plasma from subjects received ginger drinks for 30 days (C). All samples were extracted with ethanol and injected in Lichosphere 5m OD2 column.

55 CONCLUSSION In human study, using male adult healthy subjects, there is improvement in T cells proliferation activities and percentage. Improvement on T cells was accompanied by resistance of lymphocyte cells against oxidative stress. This improvement was demonstrated by the cells obtained from the subjects drinking ginger Resistance of the lymphocytes was not accompanied by decrease in MDA cell Beside the role of ginger compounds as protectant against oxidative stress, they appeared to have other immunoenhancement activity, notably in improving NK cell activity. This improvement in NK cell activity had been observed in the male student studied receiving ginger drink for 30 days analysis of ginger substances in the plasma reveal the presence of the assumed gingerol group in the plasma of subjects drinking ginger, higher than that of the control group. Since NK cells are known to have specific activity in lysing mutated or infected cells, the results of this research has shown the scientific support of the traditional beliefs that ginger can improve body resistance to common cold.

HEALTHY DESSERT MAKANAN PENCUCI MULUT SEHAT MAKANAN PENCUCI MULUT FUNGSIONAL PANGAN (PENCUCI MULUT) FUNGSIONAL AKTIFITAS ANTI KANKER GEL CINCAU HIJAU (Cyclea barbata L.Miers) Fransiska Rungkat-Zakaria, Endang Prangdimurti, Edna Ananta, Albertus Seno Pandoyo

58 PENDAHULUAN Secara tradisional, tanaman cincau hijau (Cyclea barbata L. Miers) digunakan sebagai obat penurun panas, obat radang lambung, mual, dan penurun tekanan darah tinggi. Minuman cincau merupakan produk olahan yang berbentuk gel dan dibuat dari daun cincau hijau melalui proses extraksi dingin. Beberapa laporan hasil penelitian menunjukkan bahwa tanaman cincau mempunyai aktivitas sitotoksik dan antimalaria (Guinaudeau, 1993). Aktivitas sitotoksik ini dihipotesiskan dapat menghambat proliferasi sel kanker atau sel tumor di dalam tubuh..

59 Informasi ilmiah mengenai khasiat gel cincau hijau akan mendukung perkembangan produk pangan fungsional yang berbentuk “healthy dessert”, yang akhir-akhir ini amat digemari karena dapat mengimbangi konsumsi diet mengandung lemak dan protein hewani tinggi dan kadar serat rendah. Kanker merupakan penyakit yang diawali dari mutasi gen seluler, yang diketahui sebagian besar disebabkan oleh faktor external seperti polutan kimia baik pada makanan maupun lingkungan, virus, dan radiasi. Mekanisme pencegahan mutasi gen dapat terjadi melalui aktifitas antioxidan, perbaikan imunitas, atau sitotoksik (WCRF&AICR, 1997; Zakaria-Rungkat et al., 2001)

60 METODA PENELITIAN Extraksi air daun segar dengan aquades dilakukan secara manual karena terbentuk gel yang kemudian didinginkan untuk memperoleh cairan sineresis. Extrak air daun, akar dan batang dikeringbekukan. Extrak etanol dan hexan dilakukan pada daun, akar dan batang keringbeku. Extrak di tambahkan pada media kultur sel-sel kanker K562 (turunan sel leukimia) dan Hela (turunan sel kanker servix) dan pada kultur sel limfosit yang diisolasi dari darah tepi seorang mahasiswa sehat, dengan 5 tingkat konsentrasi: C1 (1/2 C2); C2 (setara dengan konsumsi segelas minuman cincau), C3 (2xC2); C4 (4xC2); C5 (8xC2).

61 Gambar 1. Efek sitotoksik extrak air (ai), etanol (et) dan hexan (he) dari daun (d), batang (b) dan akar (a) tanaman cincau hijau terhadap pertumbuhan sel leukemia (K562). Extrak air akar mempunyai persentase penghambatan diatas 61%, air batang diatas 30%, sedang air daun diatas 37% setelah konsentrasi diatas C3. Peningkatan konsentrasi > C3 (2x 2 gelas muniman gel cincau) tidak nyata menaikkan aktifitas sitotoksik.

62 Gambar 2. Aktifitas sitotoksik extrak air (ai), etanol (et) dan hexan (he) dari daun (d), batang (b) dan akar (a) tanaman cincau hijau terhadap kehidupan sel kanker servix (Hela).Ekstrak Aia hingga konsentrasi C4 (setara 4 gelas minuman gel cincau) menghambat pertumbuhan sebesar 31%, extrak aid 22% pada konsentrasi C4.
