  Bioactive phloroglucinols from the brown alga Zonaria diesingiana	Three phloroglucinols with a C-20 acyl side chain were isolated from marine brown alga Zonaria diesingiana. The structures were determined on the basis of NMR spectral analyses and comparison with data in the literature. They all showed antibacterial activity against Bacillus subtilis and Staphylococcus aureus and cytotoxic activity by inhibiting cell division in fertilized sea urchin eggs (Echinometra mathaei). These activities suggest their possible for pharmacological purposes. These phloroglucinols also showed toxicity against brine shrimp (Artemia salina), guppy fish (Poecilia reticulata), rice-land shrimp (Macrobrachium lanchesteri) and the diatom Chaetoceros gracilis. They probably act as chemical defenses against herbivores and also reduce surface fouling by epiphytic algae and larvae, suggesting their important roles in the marine ecosystem.

  A New Glycolipid Isolated from Brown Algae Zonaria diesingiana	A new glycolipid 1, 3 -hexadecylcarbonyloxy-2-（16＂Z） - henicosylcarbonyloxy-glycerol -1-β-D-galatoside was isolated from brown algae Zonaria diesingiana collected from South China Sea. Its structure was characterized by spectroscopic analyses.	MENG, Liqiong,MA, Bo,ZHOU, Bihua,LIU, Lijuan,YAN, Sujun,MA, Lin,SU, Jingyu,ZENG, Longmei		상세보기
  A simple preparation of 17(R)-hydroxyeicosatetraenoic and eicosapentaenoic acids from the eicosanoylphloroglucinols, components of the brown alga, Zonaria diesingiana	Abstract The alkaline treatment of 17(R)-hydroxyeicosatetraenoylphloroglucinol and eicosapentaenoylphloroglucinol, which are the major components of the methanol extract of the brown alga, Zonaria diesingiana (Dictyota) afforded 17(R)-hydroxyeicosatetraenoic and eicosapentaenoic acids, respectively, in good yields. The conformation of methyl ester of the 17(R)-hydroxy acid in a solution was studied by using 2NMA, a chiral anisotropic reagent. The alkaline treatment of the title compounds afforded 17(R)-hydroxyeicosa-tetraenoic and eicosapentaenoic acids, respectively, in good yields.	Munakata, Tatsuo,Ooi, Takashi,Kusumi, Takenori		상세보기
