Aqueous extraction and HPLC separation techniques were used to quantify two major bromophenols naturally present in the red algaNeorhodomela larix: lanosol (2,3-dibromo-4,5-dihydroxybenzyl alcohol) and its 1,4-disulfate ester. Maximum concentrations of each compound were as high as 1.5% on a wet mass basis. The within-plant distributions of lanosol and its ester were highly variable on centimeter scales: adjacent portions often varied by an order of magnitude in bromophenol content. Some bromophenol variation was related to algal phase, location within the algal thallus, and reproductive status. Bromophenol concentrations were higher in exterior vegetative regions and some reproductive structures (cystocarps and tetrasporangial branchlets) than in interior vegetative regions or male reproductive structures (spermatangial stichidia). In contrast to results reported for harvestedN. larix, there was no evidence that the intactin situ algae released either compound into seawater.
采用水提取和高效液相色谱分离技术，对红藻 Neorhodomela larix 中存在的两种主要溴酚进行定量分析：拉索醇（2,3-二溴-4,5-二羟基苄醇）及其 1,4-二硫酸盐酯。每种化合物的最高浓度高达湿重的 1.5%。在厘米尺度上，拉索醇及其酯在植物体内的分布高度可变：相邻部分的溴酚含量往往相差一个数量级。一些溴酚的变化与藻类阶段、藻类叶状体内部的位置和生殖状态有关。在外部营养区域和一些生殖结构（囊果和四分孢子枝）中的溴酚浓度高于内部营养区域或雄性生殖结构（精囊梗）。与已报道的收获的 N. larix 结果相反，没有证据表明完整的原位藻类将任何一种化合物释放到海水中。
