Tagetes minuta L. - Asteraceae - huacatay (span.), southern marigold, Mexican marigold, Mexikanische Studentenblume
Annual herb, 30-100cm high, native to South America, naturalized and cultivated elsewhere; leaves lanceolate to linear; flowers tiny, yellow-white.
„It is used as a culinary herb in Peru, Ecuador, and parts of Chile and Bolivia. It is called by the Quechua terms wakatay in Peru or wakataya in Bolivia… Wakatay paste is used to make the popular Peruvian potato dish called ocopa“ http://en.wikipedia.org/wiki/Tagetes_minuta
Main components of the essential oil of the flowers are β-ocimene (31-47%) and tagetenone (34-36%), furthermore dihydrotagetone (1-6%), tagetone (3-8%), limonene (4-6%) and β-phellandrene (1%).
The essential oil of the leaves contains dihydrotagetone (28-47%) as main component, with β-ocimene (12-17%), tagetenone (8-18%), tagetone (12-18%), limonene (11-13%) and β-phellandrene (2%).

„The essential oil from the leaves of Tagetes minuta L., growing wild in Yemen, was obtained by hydrodistillation and analyzed by gas chromatography–mass spectrometry. A total of 28 compounds were identified representing 74.2% of total oil composition. Major components of the essential oil were (Z)-ocimenone (15.9%), (E)-ocimenone (34.8%), (Z)-β-ocimene (8.3%), limonene (2.3%), (Z)-tagetone (1.8%), dihydrotagetone (1.4%) and an unidentified dimethylvinylketone derivative (20.6%). The oil showed moderate cytotoxic activity against MCF-7 breast tumor cells, … and .. potent antiradical activity. Antimicrobial activity was also investigated on several microorganisms, and the essential oil exhibited high activity against methicillin-resistant Staphylococcus aureus (MRSA) with aninhibition zone of 23 mm. It also exhibited remarkable antifungal activity against Candida albicans with an inhibition zone of 26 mm.“
