1′S-1′-Acetoxyeugenol acetate: A new chemotherapeutic natural compound against MCF-7 human breast cancer cells by Nagoor, Noor Hasima, In, Lionel Lian Aun, Azmi, Mohamad Nurul, Aziz, Ahmad Nazif, Thirthagiri, Eswary, Ibrahim, Halijah, Awang, Khalijah

“…In this report, we describe the cytotoxic and apoptotic properties of 1′S-1′-acetoxyeugenol acetate (AEA), an analogue of 1′S-1′-acetoxychavicol acetate (ACA), isolated from the Malaysian ethno-medicinal plant Alpinia conchigera Griff (Zingiberaceae) on human breast cancer cells. Data from MTT cell viability assays indicated that AEA induced both time- and dose-dependant cytotoxicity with an IC50 value of 14.0 μM within 36 h of treatment on MCF-7 cells, but not in HMEC normal control cells. …”

Essential Oil Constituents of Alpinia scabra and Alpinia murdochii, Two Wild Highland Species from Peninsular Malaysia and Their Anti-Microbial Activity by Syamsir, Devi Rosmy, Tohar, Norsita, Ibrahim, Halijah, Mohamad Ali, Nor Azah, Mokhtar, Mastura, Sivasothy, Yasodha, Awang, Khalijah

“…This study investigates the chemical constituents of essential oils and their anti-microbial activity of Alpinia scabra and Alpinia murdochii, two wild Zingiberaceae species. The essential oils were obtained by hydrodistillation and the chemical components of the oils were determined by GC-FID (retention indices, RI) and GC/MS analysis. …”
