The total alkaloid content and individual alkaloid composition were determined by colorimetry and high performance liquid chromatography, respectively, for Canadian triticale and barley ergot (Claviceps purpurea). The total alkaloid content was highly variable between individual sclerotia from the same or different sources and ranged from 0.042 to 0.752% for triticale and from 0.082 to 1.04% for barley; average values were 0.239% for Ottawa triticale, 0.289% for Prairie triticale, and 0.264% for barley. Ergocristine and its isomer ergocristinine were the major constituents in both grains. On average, Canadian ergot pooled from rye, wheat, triticale, and barley consists of ergocristine (31%), ergocristinine (13%), ergocristinine (13%), ergotamine (17%), ergotaminine (8%), ergocryptine (5%), ergocryptinine (3%), ergometrine (5%), ergometrinine (2%), ergosine (4%), ergostinine (2%), ergocornine (4%), ergocorninine (2%), and unidentified alkaloids (3%), and an average total alkaloid content of 0.236%. With the exception of rye and barley ergot from the maritime regions, Canadian rye, wheat, triticale, and barley ergot is fairly uniform in individual alkaloid composition.
分别采用比色法和高效液相色谱法测定了加拿大小黑麦和大麦麦角菌（麦角菌）中的总生物碱含量和单个生物碱成分。同一来源或不同来源的单个菌核之间，总生物碱含量差异很大，小黑麦的总生物碱含量在0.042%至0.752%之间，大麦的总生物碱含量在0.082%至1.04%之间；渥太华小黑麦的平均值为0.239%，草原小黑麦的平均值为0.289%，大麦的平均值为0.264%。麦角新碱及其异构体麦角新宁是两种谷物中的主要成分。平均而言，从黑麦、小麦、小黑麦和大麦中收集的加拿大麦角菌由麦角新碱（31%）、麦角新宁（13%）、麦角新宁（13%）、麦角胺（17%）、麦角胺宁（8%）、麦角隐亭（5%）、麦角隐亭宁（3%）、麦角新碱（5%）、麦角新宁（2%）、麦角生碱（4%）、麦角生宁（2%）、麦角柯宁碱（4%）、麦角柯宁宁（2%）和未鉴定的生物碱（3%）组成，总生物碱平均含量为0.236%。除了来自沿海地区的黑麦和大麦麦角菌外，加拿大黑麦麦角菌、小麦麦角菌、小黑麦麦角菌和大麦麦角菌在单个生物碱成分上相当均匀。
