Asteraceae Family

Pot Marigold (Calendula officinalis L.) is an annual ornamental plant with yellow to orange flowers which belongs the the Asteraceae family, its flowers are used in the pharmaceutical, cosmetic and food industries. The commercial samples of seeds (n=24) of C officinalis were cultivated in home gardens in Estonia. Total carotenoid contents, determined spectrophotometrically (λ=455 nm) in the inflorescences, varied from 0.7 to 2.7%, the cultivar with the highest carotenoid content was ‘Dracon’. The total content of flavonoids, determined spectrophotometrically (λ=370 nm), varied from 0.8% to 1.7%. The best cultivar contained almost maximum amount of total carotenoids (2.5%) and flavonoids (1.7%) was ‘Radio”. The oil yields of eight cultivars of C officinalis obtained were from 0.10 to 0.43%, the highest yield (0.43%) of the oil was obtained from the cultivar ‘Double Ball’. A total 70 compounds were identified and analysed by GC-MS in the essential oil of C officinalis, representing over 95% from total oil. The major components of the oils (>5%) of C. officinalis cultivars were α-cadinole (18.4-32.0%), γ-cadinene (9.7-18.9%), viridiflorol (2.0-10.0%), τ-cadinole (4.7-7.9%), δ-cadinole (3.3-5.6%), and γ-muurolene (0.8-5.1%). There is no clear relation between the colour of the inflorescences of C. officinalis and the total content of flavonoids and carotenoids. The chemotypes of essential oils of C. officinalis were not found among the cultivars studied.

The aim of the present study was to investigate the content of total carotenoids in different collections of pot marigold ( Calendula officinalis L.) inflorescences. Commercial seeds (42 samples) of C. officinalis were obtained from nine countries and cultivated in private gardens in three different counties of Estonia. The content of total carotenoids, determined spectrophotometrically (Λ=455 nm) varied in the investigated collections from 0.20 to 3.51%. The amount of pigments may depend on the type of plants, the importing company, the color of the ligulate and tubular florets, and the place and time of cultivation. For medicinal purposes, C. officinalis with brownish-yellow ligulate and tubular florets should be preferred. The best was found to be ‘Golden Emperor’ from Finland.
