Chemical constituents of Citrus sinensis var. Shukri from Pakistan.
The variety 'Shukri' is a new hybrid of Citrus sinensis and is frequently grown for its sweet edible fruits in the southern part of Pakistan. The leaves of this hybrid variety have been investigated in search of secondary metabolites for the first time. As a result of chromatographic analysis of the methanolic extract, a new ceramide along with a flavonone glycoside and two steroids has been isolated, which were spectroscopically characterized as (E)-N-(1,3,4,5-tetrahydroxyhexadecan-2-yl)dec-4-enamide (1), atripliside B (2), beta-sitosterol (3), and beta-sitosterol-3-O-beta-D-glucopyranoside (4), respectively. Compound 1 was found to be a new addition in the list of natural products, whereas, to the best of our knowledge, compounds 2-4 have been isolated for the first time from this source.
