Anthemis cotula

Examples of other antimicrobial flavonoids from the Anthemideae tribe also included those from the Argentinian Tagetes [236], from Anthemis cotula L. [237], six flavonols isolated from Helichrysum conglobatum (Viv.) Steud. growing in Egypt [238] and another Helichrysum species, Helichrysum compactum Boiss., which yielded several flavonoids with antibacterial and antifungal activity [239]. 

An epidemic of bullous irritant dermatitis (and one with erythema multiforme) was seen in 14 farm workers whose work included pulling weeds (chiefly Anthemis cotula) in a field of sugar beets [146]. The eruption began the second day in which they worked in the specific field and manifested as erythematous macules to blisters on the lower legs, wrists, forearms and abdomen. One patient experienced erythema multiforme. This parallels the report of a single case in 1921 [147]. The weed gets its name from its tendency to bloom in May in many geographic locations. 

These types have been encountered in higher plants, bryophytes and marine organisms. Examples from higher plants are calacone (374) from essential oil of Acorus calamus (404), keto-lactone (375) from Anthemis cotula (55), and artemone (376) from davna oil (ex Artemisia pallens) (289).
