Novel Indoloquinoline Alkaloid Glycosides from Cryptolepis Sanguinolenta (lindl.) Schltr.
Natural product research(2023)
摘要
To explore the phytochemistry of the African ethnomedicinal plant Cryptolepis sanguinolenta (Lindl.) Schltr. (Apocynaceae) for rare indoloquinoline alkaloids, two novel indoloquinoline alkaloid glycosides, namely Cryptospirosanguine A (1) and B (2), were isolated from an ethanolic extract of the root. Their structures were elucidated based on spectral evidence. Furthermore, two known terpenoids were isolated from this plant for the first time.
