Title	Toward better annotation in plant metabolomics: isolation and structure elucidation of 36 specialized metabolites from Oryza sativa (rice) by using MS/MS and NMR analyses
Description	We isolated and elucidated the structures of specialized metabolites from rice by using MS/MS and NMR. Thirty-six compounds, including five new flavonoids and eight rare flavonolignan isomers, were isolated from the rice leaves. The MS/MS spectral data of the isolated compounds, with a detailed interpretation of MS fragmentation data, will facilitate metabolite annotation of the related phytochemicals by enriching the public mass spectral data depositories, including the plant-specific MS/MS-based database, ReSpect.

Title	Plant material
Description	Rice plants (cultivar Habataki) were grown in plastic pots containing granular soil (Bonsoru No.2; Sumitomo Chemical, Tokyo); after approximately 10 weeks of incubation, shoots were collected, lyophilized, and stored at -80℃ until use (Matsuda et al. 2012).
