Seven flavonoid glycosides, including one new (1) and five previously uncharacterized (3−7), were obtained from the seeds of lychee (Litchi chinensis Sonn. cv. Heiye) by means of repetitive column chromatography and high-performance liquid chromatography (HPLC) preparation. They were identified as litchioside D (1), (−)-pinocembrin 7-O-neohesperidoside (2), (−)-pinocembrin 7-O-rutinoside (3), taxifolin
