摘　　要：目的:探讨利用基质辅助激光解吸电离飞行时间质谱(MALDI-TOF-MS)技术快速鉴定灵芝的可行性。方法:采集灵芝菌丝、子实体、孢子样本后,用Autof ms800全自动微生物质谱检测系统检测,Autof Acquirer进行分析处理。结果:经过检测,得到了灵芝的蛋白指纹图谱。其蛋白指纹图谱可以分为四部分:菌丝图谱、产孢子前子实体图谱、产孢子后子实体图谱、孢子图谱。以此初步建立数据库后,可快速鉴定未知样本是否为本品种灵芝。结论:MALDI-TOF-MS技术快速鉴定灵芝具有可行性。Objective: To explore the feasibility of rapid identification of Ganoderma lucidum by using MALDI-TOF-MS technique. Methods: The samples of Ganoderma lucidum mycelium, fruiting bodies, and spores were collected first and then detected by Autof ms800 automatic microbial mass spectrometry system and analyzed by Autof Acquirer finally. Results: After testing, the protein fingerprint of Ganoderma lucidum was obtained. Its protein fingerprint can be divided into four parts: hyphal profile, pre-sporulation fruiting body profile, post-sporulation fruiting body profile, and spore profile. After initially establishing a database with this, it is possible to quickly identify whether unknown samples are of this variety of Ganoderma lucidum. Conclusion: It is feasible for rapid identification of Ganoderma lucidum by MALDI-TOF-MS technique.
