Abstract

Musa acuminata plant is known for its edible fruits and the uses of its leaves as food wrapper in industries. Exploring it medicinal values will be an advantage because it can easily grow in Malaysia. The non-edible part which is the leaves of Musa acuminata ‘Dwarf Cavendish’ plant is analysed to determine the phytochemical constituents and antimicrobial properties. Two types of organic solvents used namely hexane and methanol. The antimicrobial properties of the extract produced were tested against Staphylococcus epidermidis and Trichophyton mentagrophytes by using disc-diffusion method. Phytochemical screening done on the sample showed that the methanolic extract contained bioactive components such as tannins, alkaloids, flavonoids, phenols, terpenoids and saponins whereas hexane extract indicated the presence of alkaloid. The methanolic extract of the leaves showed positive effects towards tested microorganisms whereas hexane extract showed vice versa. The best concentration of methanolic extract against S. epidermidis was 60 mg/ml and T. mentagrophytes were 40 mg/ml forming inhibition zone with diameter of 4.0 mm and 5.0 mm, respectively. Methanolic extract against S. epidermidis is comparable to ampicillin. Meanwhile, it is remarkable that methanolic extract of M. acuminata leaves showed stronger antifungal properties as compared to nystatin. As a conclusion, the methanolic extract of the leaves of M. acuminata ‘Dwarf Cavendish’ can be nominated as potential drug due to their antifungal properties.

Abstrak

Musa acuminata merupakan tumbuhan yang dikenali dengan buah yang boleh dimakan dan kegunaan daun sebagai pembungkus makanan dalam industri. Meneroka nilai perubatannya akan menjadi satu kelebihan kerana ia senang tumbuh di Malaysia. Bahagian yang tidak boleh dimakan iaitu daun tumbuhan Musa acuminata 'Dwarf Cavendish' dianalisis untuk menentukan juzuk fitokimia dan antimikrob. Dua jenis pelarut organik yang digunakan ialah heksana dan metanol. Sifat-sifat antimikrob ekstrak yang dihasilkan telah diuji terhadap Staphylococcus epidermidis dan Tricophyton mentagrophytes menggunakan kaedah cakera resapan. Penyaringan fitokimia dilakukan pada sampel menunjukkan bahawa ekstrak metanol mengandungi komponen bioaktif seperti tannin, alkaloid, flavonoid, fenol, terpenoid dan saponin manakala ekstrak heksana menunjukkan kehadiran alkaloid. Ekstrak metanol daun menunjukkan kesan positif terhadap mikroorganisma diuji manakala ekstrak heksana menunjukkan sebaliknya. Kepekatan terbaik ekstrak metanol terhadap S. epidermidis adalah 60 mg/ml dan T. mentagrophytes adalah 40 mg/ml membentuk zon perencatan dengan diameter masing-masing 4.0 mm dan 5.0 mm. Ekstrak metanol terhadap S. epidermidis adalah setanding dengan ampicillin. Sementara itu, ekstrak metanol daun M. acuminata jelas menunjukkan ciri-ciri antikulat lebih kuat berbanding nystatin. Kesimpulannya, ekstrak metanol daun M. acuminata 'Dwarf Cavendish' boleh dicalonkan sebagai ubat yang berpotensi berdasarkan sifat antikulatnya.
