In Vitro and In Silico Investigation of Diterpenoid Alkaloids Isolated from Delphinium chitralense
This study reports the isolation of three new C20 diterpenoid alkaloids, Chitralinine A–C (1–3) from the aerial parts of Delphinium chitralense. Their structures were established on the basis of latest spectral techniques and single crystal X-rays crystallographic studies of chitralinine A described...
