Abstract
- Two new sesquiterpenoids, 4-methylazulene-1-carbaldehyde and 4-methylazulene-1-carboxylic acid, were isolated from cultures of Calypogeia azurea . Their structures were established by spectroscopic analysis. The sodium salt of 4-methylazulene-1-carboxylic acid was a naturally occurring water-soluble azulene that displayed anti-inflammatory and anti-ulcer activity.
