Authorship and data citation: Phurpa Wangchuk, John B. Bremner, Bryan W. Skelton. CCDC 1574634: Experimental Crystal Structure Determination, 2017,  DOI: 10.5517/ccdc.csd.cc1pvjnq

Method: Virescenine hydrochloride was isolated from a Bhutanese medicinal plant, Aconitum orochryseum. Needle-like colourless crystals were obtained from acetone/diethyl ether. This compound had a melting point of  76.7-79.8oC and  an optical rotation of  [α]D24 = +16.9o (c 1.095, EtOH). Its single crystal X-ray crystallographic structure was presented here for the first time. X-ray diffraction images were measured on a Nonius KappaCCD diffractometer (Mo Kα radiation, graphite monochromator, λ=0.71073 Å) and data extracted using the DENZO package (Otwinowski and Minor, 1997). Structure solution was by direct methods (SUPERFLIP, SIR92) (Altomare et al., 1994, Palatinus and Chapuis, 2007). The structure was refined using the CRYSTALS program package (Betteridge et al., 2003). Atomic coordinates, bond lengths and angles and displacement parameters have been deposited at the Cambridge Crystallographic Data Centre (CCDC).

Crystal data: The crystal structure of virescenine hydrochloride has been assigned CCDC no. 1574634  (DOI: 10.5517/ccdc.csd.cc1pvjnq). Molecular formula: C23H38ClNO6. Chemical formula weight = 459.
