棘皮动物门由约6,000种生物组成，分布于从热带到南极的所有海域，分为五类：海百合(海百合和羽星)、海参总科(海参或海参)、海胆总科(海胆)、海星总科(海星或海星)和蛇夫总科(脆星)。在棘皮动物中，海参和海星总是含有皂苷，而皂苷通常是造成它们毒性的原因。皂苷是一种复杂的水溶性化合物，由附着在类固醇或三萜苷元上的碳水化合物部分组成，已从大量陆生植物中分离出来，但却是罕见的动物成分。在动物界，它们几乎普遍存在于海参和海星中(1)，而在海豚(2)、柳珊瑚(3-5)、海绵(6-10)和鱼类(11)中很少发现。海参皂苷的化学成分为三萜苷，而海星皂苷的化学成分为甾体苷。
The phylum Echinodermata, which comprises about 6,000 living species distributed in all seas from the tropics to the antarctic zone, is divided into five classes: Crinoidea (sea lilies and feather stars), Holothuroidea (sea cucumbers or holothurians), Echinoidea (sea urchins), Asteroidea (sea stars or starfishes) and Ophiuroidea (brittle stars). Among the echinoderms, sea cucumbers and starfishes invariably contain saponins which are generally responsible for their toxicity. Saponins, complex water soluble compounds composed of a carbohydrate moiety attached to a steroid or triterpenoid aglycone, have been isolated from a great number of terrestrial plants, but are uncommon animal constituents. In the animal kingdom they are almost ubiquitous in sea cucumbers and starfishes (1), while found only rarely in alcyonarians (2), gorgonians (3-5), sponges (6-10) and as potent shark-repelling compounds in fishes (11). Chemically, saponins from sea cucumbers are triterpenoid glycosides whereas those from starfishes are steroidal glycosides.
