Fresh leaves of Lunasia amara yield 0.1 - 0.15% of an essential oil which is almost entirely sesquiterpenoid in nature. The principal sesquiterpenes are 'GAMMA'-elemene (0.7 - 19%), germacrene-D (18 - 51%) and bicyclogermacrene (7 - 26%). There are lesser amounts of bicycloelemene (1 - 2%), 'BETA'-bourbonene (0.7 - 3%), 'BETA'-elemene (4 - 9%), 'ALFA'-farnesene (1 - 3%) and 'DELTA'-cadinene (3 - 5%)[

Some 13 alkaloids have been identified from several parts of the plant. Of these, lunacrine (which is the principle alkaloid found in the leaves) and lunasin (a related quaternary furoquinoline) both show a distinct action on muscles, evidenced by a continually increasing tone and a rapid diminution of the power of response of the muscle to stimulation. This action on muscular tone is seen not only upon isolated voluntary and smooth muscles but also upon the blood vessel walls, where a distinct contraction occurs, and upon the heart where a distinct diminution in the contractions was observed. The lethal effect of both alkaloids is due to stoppage of respiration simultaneously with that of the circulation[
