Essential Oil Composition and Bioactivity of Amomum Subulatum

Microwave-assisted hydrodistillation extracted essential oil from Amomum subulatum seeds in 70 minutes, 50 minutes faster than conventional hydrodistillation. The yield increased from 3% to 3.35%, and the oil showed improved antibacterial and antioxidant activity. This data was contributed by Sekar Nethi of the Institute of Chemical Technology.

Use Cases

• Compare extraction efficiency based on yield percentage and time metrics.
• Analyze chemical composition shifts based on the reported percentages of 1,8-cineole and α-pinene.
• Evaluate antibacterial efficacy based on activity against gram-positive and gram-negative bacteria.
• Assess antioxidant potential based on DPPH radical scavenging and IC50 values.

Strengths

• Direct comparison of two extraction methods with specific time (70 min vs 4 hr) and yield (3.35% vs 3%) metrics.
• Reports specific bioactivity results, including compound percentages (e.g., 1,8-cineole at 88-89%) and IC50 values.
• Clear methodological description of microwave-assisted and conventional hydrodistillation techniques.
