Description
The discarded tops of a prized medicinal orchid outperform its famous tuber in the test tube, Yuru Zhang and colleagues find in a 2026 metabolomics comparison. Six parts of Gastrodia elata, from stem and capsule shell above ground to seed and three tuber zones below, were profiled by mass spectrometry. Extracts were then assayed for antioxidant power and alpha-glucosidase blocking, a diabetes-relevant activity.
Chemical fingerprints split cleanly between above-ground and underground tissues. Stems and capsule shells, normally thrown away, showed the strongest antioxidant and enzyme-blocking activity, beating the conventional tuber. Two amino acids, L-arginine and L-aspartate, tracked the activity differences. The authors urge fuller use of the whole plant.
