Two novel organic amide alkaloids, 4-[(<i>E</i>)-<i>p</i>-coumaroylamino]butan-1-ol (<b>1</b>) and 4-[(<i>Z</i>)-<i>p</i>-coumaroylamino]butan-1-ol (<b>2</b>), together with a rare pyridoindole alkaloid, hippophamide (<b>3</b>), were isolated from the seed residue of <i>Hippophae rhamnoides</i> Linn. subsp. <i>sinensis</i> Rousi. Their structures were determined by spectroscopic means. The results show that compounds <b>1</b> and <b>2</b> are (<i>E</i>/<i>Z</i>)<i>-</i>isomers, compound <b>3</b>, a pyridoindole alkaloid concerted with <i>γ</i>-lactam ring.
