Monoterpenoids (3 and 4), sesquiterpenoid (2), diterpenoid (1) and four phenethyl glucosides (5-8), together with fourteen known compounds, were isolated from the whole herb of Hyssopus cuspidatus. Their structures were determined by spectroscopic means. The abietane-type diterpenoids (1, 9, 10), rosmarinic acid (15) and salvigenin (17) inhibited leukotriene (LT) C(4) secretion from primary alveolar cells of Wistar rats.
