【摘要】 本文介绍了我国南海两种海参——棕环海参(Holothuria fuscocinerea Jaegar)和紫伪翼手参(Pseudocolochirus violaceus Theel)中生物活性成分的研究。本研究以稻瘟霉模型作为活性监测手段,应用正相硅胶、反相硅胶、葡聚糖凝胶以及高效液相色谱法等多种色谱分离技术,对两种海参所含的抗肿瘤和抗真菌活性成分进行了系统的分离纯化和药理研究。共分离得到单体化合物24个(棕环海参11个,紫伪翼手参13个),应用现代波谱技术和化学手段鉴定了其中21个化合物的结构,均为首次从上述海参中获得,其中新化合物8个。 从棕环海参中分离鉴定了10个化合物,包括6个海参皂苷和4个其它化合物。6个海参皂苷的化学结构为:3-O-[3-O-甲基-β-D-吡喃葡萄糖-(1→3)-β-D-吡喃葡萄糖-(1→4)-β-D-吡喃奎诺糖-(1→2)-4-O-硫酸钠-β-D-吡喃木糖]-海参烷-9(11)-烯-3β,12α-二醇(HF-1,pervicoside C),3-O-[3-O-甲基-β-D-吡喃葡萄糖-(1→3)-β-D-吡喃葡萄糖-(1→4)-β-D-吡喃奎诺糖-(1→2)-4-O-硫酸钠-β-D-吡喃木糖]-25-乙酰氧基-海参烷-9(11)-烯-22-酮-3β,12α-二醇(HF-2,fuscocineroside A),3-O-[3-O-甲基-β-D-吡喃葡萄糖-(1→3)-β-D-吡喃葡萄糖-(1→4)-β-D-吡喃奎诺糖-(1→2)-4-O-硫酸钠-β-D-吡喃木糖]-海参烷-9(11)-烯-22-酮-3β,12α-二醇(HF-3,fuscocineroside B),3-O-[3-O-甲基-β-D-吡喃葡萄糖-(1→3)-β-D-吡喃葡萄糖-(1→4)-β-D-吡喃奎诺糖-(1→2)-4-O-硫酸钠-β-D-吡喃木糖]-22,25-环氧-海参烷-9(11)-烯-3β,12α-二醇(HF-4,fuscocineroside C),3-O-[3-O-甲基-β-D-吡喃葡萄糖-(1→3)-β-D-吡喃葡萄糖-(1→4)-β-D-吡喃奎诺糖-(1→2)4-O-硫酸钠-β-D-吡喃木糖]-22,25-环氧-海参烷-9(11)-烯-3β,12α,17α-三醇(HF-5,holothurin A)和3-O-[β-D-吡喃奎诺糖-(1→2)-β-D-吡喃木糖]-22,25-环氧-海参烷-9(11)-烯-3β,12α,17α-三醇(HF-6,DS-holoturin B);4个其它化合物为:尿嘧啶(HF-7),胸腺嘧啶(HF-8),胸腺嘧啶脱氧核苷(HF-10)和尿嘧啶脱氧核苷(HF-11)。 从紫伪翼手参中分离鉴定了1 1个化合物,包括7个海参皂苷和4个甾醇苷。7个海参皂苷的化学结构为:3-O-[3-O-甲基-β-D-吡喃葡萄糖-(1→3)-β-D-吡喃木糖-(1→4)-β-D-吡喃奎诺糖-(1→2)-4-O-硫酸钠-β-D-吡喃木糖]-16β-乙酰氧基-海参烷-7,24-二烯-3β-醇(PV-1,philinopside A),3-O-[3-O-甲基-β-D-吡喃葡萄糖-(1→3)-β-D-吡喃木糖-(1→4)-β-D-吡喃葡萄糖-(1→2)-4-O-硫酸钠-β-D-吡喃木糖]-16β-乙酰氧基-海参烷-7,24-二烯-3β-醇(PV-2,violaceside A),3-O-[3-O-甲基-β-D-吡喃

【Abstract】 Holothuria fuscocinerea and Pseudocolochirus violaceus are abundant sea cucumbers distributed in South China Sea. No chemical works have been performed on these sea cucumbers up to date. Guided by Pyricularia oryzae bioassay model, the anticancer and antifungal constituents of H. fuscocinerea and P. violaceus have been investigated by various chromatography methods including LPLC, MPLC, HPLC on silica gel, ODS RP C18 and Zorbax SB C18 respectively. Twenty-four compounds were isolated and chemical structures of twenty-one were elucidated by chemical and spectral analysis (IR, EI-MS, ESI-MS, HRESI-MS, 1H NMR, 13C NMR, 1H-1H COSY, DQCOSY, TOCSY, HMQC, HMBC, NOESY, etc).From the ethanolic extracts of H. fuscocinerea, ten compounds were isolated and identified, including six triterpene glycosides: 3-O-[3-O-methyl-β-D-glucopyranosyl-(1→3) -β-O-glucopyranosyl-(1→4)-β-D-quinovopyranosyl-(1→2)-4-O-sodiumsulfate-β-D-xylo-pyranosyl]-holosta-9(11)-ene-3β, 12α-diol (HF-1, pervicoside C), 3-O-[3-O-methyl-β-D-glucopyranosyl-(1→3)-β-D-glucopyranosyl-(1→4)-β-D-quinovopyranosyl-(1→2)-4-O-sodiumsulfate-β-D-xylopyranosyl]-25-acetoxy-holosta-9(11)-ene-22-one-3β, 12α-diol (HF-2), 3-O- [3-O-methyl-β-D-glucopyranosyl-(1→3)-β-D-glucopyranosyl-(1→4)-β-D-quinovo-pyranosyl-(1→2)-4-O-sodiumsulfate-β-D-xylopyranosyl]-holosta-9(11)-ene-22-one-3β, 12α -diol (HF-3), 3-O-[3-O-methyl-β-D-glucopyranosyl-(1→3)-β-D-glucopyranosyl-(1→4)-β-D-quinovopyranosyl-(1→2)-4-O-sodiumsulfate-β-D-xylopyranosyl]-22,25-epoxy-holosta-9(11)-ene-3β, 12α-diol (HF-4), 3-O-[3-O-methyl-β-D-glucopyranosyl-(1→3)-β-D-gluco-pyranosyl-(1→4)-β-D-quinovopyranosyl-(1→2)-4-O-sodiumsulfate-β-D-xylopyranosyl]-22,25-epoxy-holosta-9(11)-ene-3β, 12α, 17α-triol (HF-5, holothurin A) and 3-O-[β-D-quinovopyranosyl-(1→2)-β-D-xylopyranosyl]-22,25-epoxy-holosta-9(11)-ene-3β,12α, 17α-triol (HF-6, DS-holothurin B); and four other type compounds: uracil (HF-7), thymine (HF-8), thymidine (HF-10) and 2’-deoxyuridine (HF-11).From the ethanolic extracts of P. violaceus, the chemical structures of eleven compounds were elucidated, including seven triterpene glycosides: 3-O-[3-O-methyl-β-D-glucopyranosyl-(1→3)-β-D-xylopyranosyl-(1→4)-β-D-(1→2)-quinovopyranosyl-4-O-sodiumsulfate-β-D-xylopyranosyl]-16p-acetoxy-holosta-7, 24-diene-3β-ol (PV-1, philinop-side A), 3-O-[3-O-methyl-β-D-glucopyranosyl-(1→3)-β-D-xylopyranosyl-(1→4)-β-D-glucopyranosyl-(1→2)-4-O-sodiumsulfate-β-D-xylopyranosyl]-16β-acetoxy-holosta-7, 24-diene-3β-ol (PV-2), 3-O-[3-O-methyl-β-D-glucopyranosyl-(1→3)-β-D-xylopyranosyl-(1→
