Chemical composition of marigold (Calendula officinalis L.) cultivated in Republic of Macedonia, as well as the fatty acid content in the extracts of marigold whole flower, petals and repectables, were determined. The dry petals are characterised with the lowest content of total proteins, ash and sand. In dry receptacles the content of ash and proteins is the highest. Total sugars and sand contents in marigold dry whole flowers are higher then in dry petals and repectables. The highest extract yield is obtained by dichloromethane extraction of dry whole flowers. The extract yield obtained from dry petals with /i-hexane extraction is higher then those obtained from dry whole flowers and dry receptacles, under the same conditions. The content of myristic (C14:0). palmitic (C16:0). stearic (C18:0), cis-oleic (C18:l), linoleic (C18:2) and linolenic acid (CI8:3) was determined in the Calendula extracts. It is determined that in all extracts linoleic acid has the highest content. Calendula extracts are rich in oleic and linoleic acids. The content of palmitic acid is the highest compared with other saturated acids founded in the extracts.
