"The rhizome of white galangal (Alpinia galanga) is one of the cultivated remedies traditionally administered for skin disease, asthma and anabolism troubles such as colic, food poisoning, and convulsions. A part of the chemical composition of white galangal rhizome is essential oil. The aim of this study was to determine the antibacterial effect of the essential oil of white galangal rhizome against the growth of Staphylococcus aureus 302 resistant to ampicillin, amoxicillin, penicillin G, kanamycin, mecillinam, and ceftazidime. Fifty ul essential oil of white galangal rhizome in concentrations of 5, 7.5, 10, 12.5 or 15 % were dropped into 6 mm of diameter well in MHA media given to S. aureus 302. Propylene glycol (5% vol) was used as negative control and solvent. The treatment to each concentration group was repeated fifteen times. The diameter of radical zone of the growth of S. aureus 302 was measured using sliding calipers. The results of ANOVA (p<0.05) showed that the essential oil of white galangal rhizome had a significant antibacterial effect against S. aureus 302. The result of LSD test (p<0.05) showed a significant difference between the concentration groups, except for the 10 and 12.5% concentrations which had the same effect."

"ABSTRAKLengkuas (Alpinia galanga L.) banyak digunakan sebagai penyedap masakan, minuman, dan obat tradisional. Salah satu komponen kimia lengkuas yaitu sesquiterpene, bahkan telah terbukti sebagai antitumor dan antikanker. Penelitian dilakukan untuk mengetahui pengaruh pencekokan ekstrak lengkuas pada mencit (Mus musculus L.) dengan dosis 6,25; 12,5; 25; 50; 100 mg/kg bb selama 7 hari berturut-turut terhadap kerusakan sitogenetik yang diinduksi oleh mitomisin C melalui uji mikronukleus. Penghitungan mikronukleus dilakukan pada 1.000 eritrosit polikromatik. Hasil uji statistik menunjukkan bahwa ekstrak lengkuas memiliki aktivitas antimutagenik, terbukti pada dosis 6,25; 12,5; 25; 50; clan 100 mg/kg bb ekstrak lengkuas dapat menghambat kerusakan sitogenetik yang diinduksi oleh mitomisin C pada enitrosit polikromatik sumsum tulang mencit. Walaupun demikian, pencekokan ekstrak lengkuas dengan dosis yang semakin meningkat tidak menyebabkan penurunan jumlah mikronukleus. Perlu dilakukan penelitian lebih lanjut untuk mengetahui komponenkomponen kimia pada lengkuas yang memiliki aktivitas antimutagenik dan mekanisme antimutageniknya."

"ABSTRAKThe rubra variety of Alpina galanga rhizoma extract were compatible to the fibroblast tissue, non toxic, and potent in inhibiting Candida albicans growth. The purpose of this study was to find out the effect of the rubra variety of Alpina galanga rhizome extract as a treatment to oral candidosis. The patients involved in this study were 20 diabetic patients, men and woman. There were sixteen patients showed white patches or flecks on the tongue surface. After clinical examination, a direct smear was made and there were mass of candidal hyphae on Periodic Acid Schiff staining. For patient comfort, the extract of Alpinia galanga 30% was prepared as a cream in a tube. The cream was used topically on the fleck, 4-5 times daily for 14 days. In case of the flecks persisted, the treatment was continued to 21 days. Mc Nemar test showed a significant difference between the group before and after treatment (p<0,05). It was concluded that 30% rubra variety of Alpina galanga rhizome extract could be used as an alternative treatment for oral candidosis."
