Terpenoids and phenethyl glucosides from Hyssopus cuspidatus (Labiatae)

► The constituents of the EtOH extracts of Hyssopus cuspidatus were studied. ► Eight terpenoids and glucosides were isolated along with fourteen known compounds. ► Inhibitory activity of isolated compounds on the release of LTC4 was investigated. ► Abietane-type diterpenoids inhibited the secretion of LTC4 from primary alveolar cells of Wistar rats.
