Phytochemical study of the bark of some plants of the Elaeagnaceae family as a natural source of β-carboline indole alkaloids.

We have studied the qualitative and quantitative composition of β-carboline indole alkaloids that have been isolated for the first time from bark of Hippophaë rhamnoides L., Elaeagnus angustifolia L., E. orientalis L., E. umbellata Thunb., E. multiflora Thunb., and E. argentea Pursh. occurring in Russia. Results of a phytochemical study showed that the bark of all these plants contains β-carboline alkaloids and that the first four of them can be promising sources of β-carboline alkaloids for the creation of drugs.
