| Description | Arnicolide C exhibits significant antiallergy activity. |
| In vitro | One of the sesquiterpenes, 6-O-senesioylplenolin (2), is a new pseudoguaianolide sesquiterpene lactone, which was isolated along with known pseudoguaianolide, Arnicolide C (1). The two sesquiterpenes exhibited significant antiallergy activity in passive cutaneous anaphylaxis (PCA) tests. An amide isolated along with the sesquiterpenes was identified as aurantiamide acetate (3). |
