Abstract

ABSTRACT

Ficus deltoidea or locally known as Mas cotek is one of the common medicinal plants used in Malaysia. Our previous studies showed that this plant have blood glucose lowering effect. Glucose uptake into muscle and adipocytes cells is one of the known mechanisms of blood glucose lowering effect. This study was performed to evaluate the effect of Ficus deltoidea on glucose uptake activity into muscle cells. The cells were incubated with Ficus deltoidea extracts either alone or combination with insulin. Amount of glucose uptake by L6 myotubes was determined using glucose tracer, 2-deoxy-[1-3H]-glucose. The results showed that Ficus deltoidea extracts at particular doses enhanced basal or insulin-mediated glucose uptake into muscle cells significantly. Hot aqueous extract enhanced glucose uptake at the low concentration (10 µg/ml) whereas methanolic extract enhanced basal glucose uptake at high concentrations (500 and 1000 µg/ml). Meanwhile, ethanolic extract enhanced glucose uptake at low and high concentrations. Methanolic extract also mimicked insulin activity during enhancing glucose uptake into L6 muscle cells. Glucose uptake activity of Ficus deltoidea could be attributed by the phenolic compounds presence in the plant. This study had shown that Ficus deltoidea has the ability to enhance glucose uptake into muscle cells which is partly contributed the antidiabetic activity of this plant.

Abstrak

Ficus deltoidea atau tempatan yang dikenali sebagai Mas cotek merupakan salah satu tumbuhan ubatan yang biasa digunakan di Malaysia. Kajian ini dijalankan sebelumnya menunjukkan bahawa tumbuhan ini mempunyai kesan merendahkan glukosa darah. Penyerapan glukosa ke dalam sel-sel otot dan adipocytes merupakan salah satu mekanisma yang dikenali glukosa darah mengurangkan kesan. Kajian ini telah dilaksanakan untuk menilai kesan Ficus deltoidea aktiviti penyerapan glukosa ke dalam sel-sel otot. Sel-sel yang telah incubated dengan Ficus deltoidea ekstrak sama ada bersendirian atau kombinasi dengan insulin. Jumlah penyerapan glukosa oleh L6 myotubes adalah ditentukan dengan menggunakan pengesanan glukosa, 2 - deoxy-[1-3H]-glukosa. Hasil kajian menunjukkan bahawa ekstrak Ficus deltoidea pada dos tertentu dipertingkatkan penyakit atau sel-sel penyerapan glukosa diantarai insulin ke dalam otot dengan ketara. Ekstrak air panas meningkatkan penyerapan glukosa pada kepekatan rendah (10 µg/ml) manakala ekstrak methanolic meningkatkan penyerapan glukosa penyakit pada kepekatan yang tinggi (500 dan 1000 µg/ml). Sementara itu, ekstrak ethanolic meningkatkan penyerapan glukosa rendah.
