蘑菇含有多种必需营养素和促进健康的生物活性化合物，包括氨基酸L-麦角硫因。了解不同蘑菇品种的化学成分将有助于研究其促进健康的特性。我们比较了新鲜生白色按钮，crimini，portabella，狮子的马内，舞茸，牡蛎和香菇的代谢组使用非靶向液相色谱质谱（LC/MS）为基础的代谢组学。我们还定量了氨基酸浓度，包括L-麦角硫因，一种植物或动物不能合成的潜在抗氧化剂。在7个蘑菇品种中，检测到超过10，000种化合物。主成分分析表明，相同种类的蘑菇，双孢蘑菇（白色按钮，portabella，crimini），组相似。其他品种形成独立的，不同的集群。共检测到1344（520注释）化合物在所有7个蘑菇品种。每种蘑菇都有几十到几百种不同的化合物。这些数字从29个crimini到854个狮子的马内鬃毛不等。所有三个双孢蘑菇品种具有相似的氨基酸谱（包括检测到所有9种必需氨基酸），而其他品种的蛋氨酸和色氨酸较少。狮子的马内和平菇的L-麦角硫因浓度最高。检测到的数百种独特的蘑菇品种化合物强调了这些品种的食用菌的化学成分的差异。
Mushrooms contain multiple essential nutrients and health-promoting bioactive compounds, including the amino acid L-ergothioneine. Knowledge of the chemical composition of different mushroom varieties will aid research on their health-promoting properties. We compared the metabolomes of fresh raw white button, crimini, portabella, lion’s mane, maitake, oyster, and shiitake mushrooms using untargeted liquid chromatography mass spectrometry (LC/MS)-based metabolomics. We also quantified amino acid concentrations, including L-ergothioneine, a potential antioxidant which is not synthesized by plants or animals. Among the seven mushroom varieties, more than 10,000 compounds were detected. Principal Component Analysis indicated mushrooms of the same species, Agaricus Bisporus (white button, portabella, crimini), group similarly. The other varieties formed individual, distinct clusters. A total of 1344 (520 annotated) compounds were detected in all seven mushroom varieties. Each variety had tens-to-hundreds of unique-to-mushroom-variety compounds. These ranged from 29 for crimini to 854 for lion’s mane. All three Agaricus bisporus varieties had similar amino acid profiles (including detection of all nine essential amino acids), while other varieties had less methionine and tryptophan. Lion’s mane and oyster mushrooms had the highest concentrations of L-ergothioneine. The detection of hundreds of unique-to-mushroom-variety compounds emphasizes the differences in chemical composition of these varieties of edible fungi.
