Flavonoids from the Aerial Part of Pelargonium graveolens and Their Antoxidant Activity.

This article discusses a study on the antioxidant activity of flavonoids found in Pelargonium graveolens, a plant commonly used in perfumes, cosmetics, and pharmaceuticals. The study focuses on the aerial part of the plant, which was collected in Yunnan Province, China, and extracted using methanol. Ten compounds, including kaempferol, quercetin, apigenin, and icariin, were identified through chromatographic and purification techniques. The research highlights the antioxidant capabilities of these flavonoids, with quercetin, quercetin-3-O-β-D-galactopyranoside, myricitrin, and (–)-epigallocatechin-3-gallate showing particularly strong antioxidant activity. The authors express gratitude to the State Key Laboratory of Phytochemistry and Plant Resources for their assistance. [Extracted from the article]
