Mulberry is an important economic crop plant and traditional medicine. It contains a huge array of bioactive metabolites such as flavonoids, amino acids, alkaloids and vitamins. Consequently, mulberry has received increasing attention in recent years. MMHub (version 1.0) is the first open public repository of mass spectra of small chemical compounds (<1000 Da) in mulberry leaves. The database contains 936 electrospray ionization tandem mass spectrometry (ESI-MS2) data and lists the specific distribution of compounds in 91 mulberry resources with two biological duplicates. ESI-MS2 data were obtained under non-standardized and independent experimental conditions. In total, 124 metabolites were identified or tentatively annotated and details of 90 metabolites with associated chemical structures have been deposited in the database. Supporting information such as PubChem compound information, molecular formula and metabolite classification are also provided in the MS2 spectral tag library. The MMHub provides important and comprehensive metabolome data for scientists working with mulberry. This information will be useful for the screening of quality resources and specific metabolites of mulberry. Database URL: https://biodb.swu.edu.cn/mmdb/.

MMHub,桑树代谢组的数据库。

桑树是重要的经济作物和传统药物。它含有大量的生物活性代谢物,例如类黄酮,氨基酸,生物碱和维生素。因此,桑树近年来受到越来越多的关注。MMHub(1.0版)是桑树叶片中第一个小型化合物(<1000 Da)质谱图的开放式公共数据库。该数据库包含936个电喷雾电离串联质谱(ESI-MS2)数据,并列出了91种桑树资源中化合物的特定分布,其中有两个生物学重复。ESI-MS2数据是在非标准化和独立的实验条件下获得的。总共鉴定或初步注释了124种代谢物,并将90种具有相关化学结构的代谢物的详细信息存储在数据库中。MS2光谱标签库中还提供了支持信息,例如PubChem化合物信息,分子式和代谢物分类。MMHub为从事桑树研究的科学家提供重要而全面的代谢组学数据。这些信息将有助于筛选优质资源和桑树的特定代谢产物。数据库URL:https://biodb.swu.edu.cn/mmdb/
