Biological Activities of Essential Oils Hydrodistillated from Two Closely Related Ginger Species: Alpinia malaccensis var. nobilis and Alpinia latilabris leaves
The essential oils of A. malaccensis var. nobilis and A. latilabris were initially screened for antimicrobial activity against eleven microbes using the qualitative BacTiter GloTM kit followed by IC50 determination using the quantitative protocol of the same kit. The antioxidant activities were dete...

The antioxidant activities were determined using DPPH radical scavenging test, ABTS and FRAP analysis. A. malaccensis var. nobilis showed inhibition of growth of 10 out of 11 microbes tested, with the most significant result observed for C. tropicalis and C. neoformans having IC50 of 1.75 mg/mL and 1.97 mg/mL, respectively. A. latilabris inhibited the growth of 8 out of 11 microbes, with the highest inhibition against K. pneumonia, having IC50 of 18.83 mg/mL. A. malaccensis var. nobilis also had a better antioxidant activity compared to A. latilabris.
