嵊山岛海洋药用生物资源状况调查

对嵊山岛礁生物资源以及邻近海域的微藻资源调查,共发现121种潮间带生物,其中有28种海洋药用生物,包括红条毛肤石鳖(Acanthochiton rubrolineatus)、马粪海胆(Hem icentiotus pulcherrimus)、海萝(Gloiopeltis furcata)等,其中多数是海洋中药或可制成中成药,嵊山岛丰富的海绵资源具有筛选天然活性物质的潜力。嵊山岛邻近海域的产毒藻类包括产麻痹性贝毒(PSP)的链状亚历山大藻(Alexandrium catenatum)、塔玛亚历山大藻(Alexandrium tamarens),产腹泻性贝毒(DSP)的倒卵形鳍藻(D inophysis forti)、具尾鳍藻(D inophysis caudata);产记忆缺失性贝毒(ASP)的尖刺拟菱形藻(Pseudo-Nitzschia pungens)、多列拟菱形藻(Pseudo-Nitzschia multiseries)和多纹拟菱形藻(Pseudo-Nitzschia multistriata);产神经性贝毒(NSP)的短凯伦藻(Kerina breve)以及红色裸甲藻(Gymnodinium sangium)、米氏凯伦藻(Kerina m ikim oto)、环状异甲藻(Heterocapsa circularisqua-ma)等能产生生理活性物质的藻类,其中嵊山岛邻近海域产石房蛤毒素和神经毒素的有毒藻类可能具有药用开发价值。

The Preliminary Investigation of Marine Drug Organisms in Shenshan Island

The marine organisms in the tideland and nearby sea area of Shenshan island have been investigated.There were 121 marine organisms on the tidelands including 28 species of marine drug organisms,such as Acanthochiton rubrolineatus、Hemicentiotus pulcherrimus、Gloiopeltis furcata etc.Many of them are marine Chinese crude drugs or capable of being produced to Chinese patent drugs and the abundant marine sponge resources in Shenshan island are potential to be screened for active materials.According to the preliminary investigation in nearby sea area of Shenshan island during 2003 and 2004,there were 11 toxic algae including PSP causing algae(Alexandrium catenatum,Alexandrium tamarens),DSP causing algae(Dinophysis acuminata,Dinophysis forti),ASP causing algae(kerina breve),NSP causing algae(Pseudo-Nitzschia pungens,Pseudo-Nitzschia multiseries,PseudoNitzschia multistriata),and other toxic algae may include active material(Gymnodinium sangium,kerina mikimoto,Chatenela marina,Heterisigma akashiwo,Heterocapsa circularisquama).Saxitoxin and brevetoxin producing algae are potential to pharmacy application.
