Abstract
  1. Suitable conditions have been determined for growing the fungus Phoma foveata in culture for optimum production of pigments. 2. The pigments have been extracted and fractionated according to their solubility in aqueous bicarbonate, carbonate and alkali. 3. The carbonate- and alkali-soluble pigments have been further separated by chromatography and shown to consist of anthraquinone derivatives. 4. The alkali-soluble fraction, which comprised the bulk of the pigment, consists of pachybasin (1-hydroxy-3-methylanthraquinone; II) and chrysophanol (1,8-dihydroxy-3-methylanthraquinone; III) by comparison with authentic samples. 5. The carbonate-soluble fraction contains emodin (1,6,8-trihydroxy-3-methylanthraquinone; V) and a hitherto unrecorded pigment for which the name phomarin and the structure 1,6-dihydroxy-3-methylanthraquinone (IV) are put forward. 6. The identification of emodin and the structural determination of phomarin are based largely on their ultraviolet, visible, infrared, nuclear-magnetic-resonance and mass spectra.
摘要
  1. 已确定了适合培养黄斑茎点霉以实现色素最佳产量的条件。2. 已根据色素在碳酸氢盐水溶液、碳酸盐溶液和碱中的溶解度进行提取和分级分离。3. 可溶于碳酸盐和碱的色素通过色谱法进一步分离,并显示由蒽醌衍生物组成。4. 与标准样品相比,占色素大部分的碱溶性部分由粗糠醛(1-羟基-3-甲基蒽醌;II)和大黄酚(1,8-二羟基-3-甲基蒽醌;III)组成。5. 可溶于碳酸盐的部分含有大黄素(1,6,8-三羟基-3-甲基蒽醌;V)和一种迄今未记录的色素,为此提出了“茎点菌素”这一名称以及结构1,6-二羟基-3-甲基蒽醌(IV)。6. 大黄素的鉴定和茎点菌素的结构测定主要基于它们的紫外光谱、可见光谱、红外光谱、核磁共振光谱和质谱。
