从甲醇溶液中提取l -抗坏血酸（C6H8O6，即维生素C），在平板玻璃培养皿上进行了晶体生长的形态图。l -抗坏血酸在甲醇溶液中不同的湿度和初始浓度，观察到三种不同的生长模式：均匀盘状、同心圆状和枝晶状。此外，在较高的浓度下，在任何低于90%的湿度下都能生长出清晰的小单晶。从一种模式到另一种模式的交叉也被观察到。
Morphological diagram with respect to crystal growth of L-ascorbic acid (C6H8O6; so-called vitamin C) from methanol solution on a flat glass dish is presented. Varying humidity and initial concentration of L-ascorbic acid in methanol solution, the following three distinct kinds of growing patterns have been observed: homogeneous disk, concentric ring and dendrite. In addition, in higher concentration clearly faceted small single crystals grow in any humidity less than 90%. Crossovers from one pattern to another were observed, too.
