Biological Activity

Description

Croomine is a tuberostemospironine-type alkaloid. Croomine can be found in Stemona tuberosa, Croomia heterosepala, and Croomia japonica^[1].

In Vitro

Croomine (compound 2) (95% ethanol, 4% HCl, 35% aqueous NH₃, hexane:EtOAc (1:1); 2 h ethanol reflux, repeated 2 times) is a naturally occurring tuberostemospironine-type alkaloid isolated from Stemona tuberosa, with a total isolated yield of 840 mg, a retention time of 9.26 min in HPLC-ELSD analysis, and fully assigned NMR spectroscopic data in deuteropyridine solvent^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
