Process to manufacture 4-methoxybenzoic acid from herbal anethole and the use of 4-methoxybenzoic acid in cosmetic and dermatologic products as well as foodstuffs.[Reference: WebLink]

METHODS AND RESULTS:
A process to manufacture 4-Methoxybenzoic acid from anethole. This raw material can be obtained from a variety of plant materials and thus offers a renewable alternative to fossil raw materials. Another aspect of the present invention is the use of 4-Methoxybenzoic acid gained from vegetal anethole as raw material in cosmetic and dermatologic products and/or aroma components in foodstuffs.

Antioxidant and radical scavenging properties of Malva sylvestris.[Pubmed: 19731587]

Antioxidant capacity of the aqueous extract of Malva sylvestris was measured by its ability to scavenge the DPPH and superoxide anion radicals and to induce the formation of a phosphomolybdenum complex.
METHODS AND RESULTS:
Analysis of the extract, carried out by different chromatographic techniques, led to the isolation of eleven compounds: 4-hydroxybenzoic acid, 4-Methoxybenzoic acid, 4-hydroxy-3-methoxybenzoic acid, 4-hydroxycinnamic acid, ferulic acid, methyl 2-hydroxydihydrocinnamate, scopoletin, N-trans-feruloyl tyramine, a sesquiterpene, (3R,7E)-3-hydroxy-5,7-megastigmadien-9-one, and (10E,15Z)-9,12,13-trihydroxyoctadeca-10,15-dienoic acid.
CONCLUSIONS:
The antioxidant activities of all these compounds are reported.
