Description

Gitingensine is a steroidal alkaloid which occurs in Kibatalia gitingensis, being found mainly in the leaves. It is optically active with a specific rotation of [α]31D - 65° (CHCI3). The hydrochloride has m.p. 281°C; [α]23D - 59.8° (CHCI3) and is more readily obtainable in the pure form than the free base. Deamination of the alkaloid by diazotization gives the deamino derivative, m.p. 235°C. The amino group may be methylated to yield the N-methyl compound, m.p. 223-4°C but the base cannot be methylated further.

Definition

ChEBI: Gitingensine is a steroid. It has a role as a metabolite.
