During routine screening of illegal adulterants in health supplements, a novel sildenafil analogue was discovered, and subsequently isolated by recrystallization. Its structure was elucidated by extensive analyses of high resolution mass spectrometry (HRMS), one-dimensional (1D) and two-dimensional (2D) nuclear magnetic resonance (NMR) data. The analogue was finally determined as hydroxycarbodenafil, featuring a hydroxyethyl group instead of an ethyl group on piperazine ring in comparison with carbodenafil.

一种新西地那非类似物羟基卡地那非的分离和鉴定，该类似物在健康补品中被掺假。

在常规筛查健康补品中的非法掺假品期间，发现了一种新型西地那非类似物，随后通过重结晶进行了分离。通过对高分辨率质谱（HRMS），一维（1D）和二维（2D）核磁共振（NMR）数据的广泛分析，阐明了其结构。最终将该类似物确定为羟基卡地那非，与卡本地那非相比，其特征在于羟乙基而不是哌嗪环上的乙基。
