A silychristin isomer and variation of flavonolignan levels in milk thistle (Silybum marianum) fruits.
A new natural product has been isolated from silymarin, the hepatoprotective extract of milk thistle (Silybum marianum) fruits. This was shown by NMR spectroscopy to be silychristin B (8), a diastereoisomer of the known silychristin (7). Levels of these and the other flavonolignans varied markedly in fruits of different S. marianum samples.
