Crocetin from the tubular calyx of Nyctanthes arbor-tristis.
A carotenoid aglycone Ag-NY1 was isolated from the orange coloured tubular calyx of flowers of Nyctanthes arbor-tristis. The elucidation of the structure through a detailed spectroscopic study revealed that the carotenoid molecule is crocetin, which is the major aglycone present in the stigma of Crocus sativus. The compound exhibited a good membrane stabilising activity as compared to the corresponding glycoside crocin.
