Scientific studies on health uses and benefits of pink torch ginger
• Antioxidative Constituents:
Phytochemical studies on the rhizomes of Etlingera elatior isolated compounds found to inhibit lipid peroxidation in a more potent manner than a-tocopherol.
• Antimicrobial / Cytotoxic:
A study on the ethanol extracts of 19 Malaysian traditional vegetables (ulam) for antimicrobial and cytotoxic activities. Etlingera elatior showed antimicrobial activity and cytotoxic activity against human cervical carcinoma cell line.
• Antioxidant / Antibacterial:
Methanolic extracts from the fresh leaves of Etlingera species were screened for total phenolic content, antioxidant and antibacterial activity. Significant antioxidant activity was found in the leaves of E. elatior; total phenolic content and antioxidant activity were highest in the leaves, followed by inflorescences and rhizomes. Leaves of Etlingera species exhibited antibacterial activity against Gram-positive bacteria.
• Volatile Oils:
The major components identified in the oils of inflorescence and inflorescence axis of E. elatior were dodecanol, dodecanal and a-pinene.
• Volatile Oils:
Phytochemical study showed the essential oils depended on the part of the paltn studied–sesquiterpenes hydrocarbons were highest with the essential oils of the leaves; in the stems and rhizomes, oxygenated monoterpene derivatives; in the flowers, monoterpene hydrocarbons.
Study of 12 Thai medicinal plants for anti-fungal potential showed the flower buds of E elatior demonstrated high inhibitory activity against C gloeosporioides mycelial growth and suggests a potential for the control of anthracnose diseases.
