title: Cytotoxic and antioxidative sesquiterpenoids from Heterotheca inuloides.
abstract: Four sesquiterpenoids, beta-caryophyllene, beta-caryophyllene 4,5 alpha-oxide, 7-hydroxy-3,4-dihydrocadalin, and 7-hydroxycadalin, isolated from the dried flower of Heterotheca inuloides Cass. (Asteraceae), have been found to exhibit cytotoxic activity against several solid tumor cell lines. Among them, 7-hydroxy-3,4-dihydrocadalin and 7-hydroxycadalin have also been found to inhibit autoxidative and microsomal lipid peroxidation.
