General characteristics of 1,679 naturally occurring compounds in Citrullus lanatus. (A) Distribution of molecular weights of compounds comprising the catalog. Bins from 75 to 600 are sized by 25 units, from 600 to 1,000 by 50 units, and from 1,000 to 1,200 by 100 units. (B) Distribution of watermelon compounds containing atoms of nitrogen (N), phosphorus (P), and/or sulfur (S). The text “w/o” indicates without, e.g., compounds without phosphorus and sulfur in the leftmost column of the plot. (C) Distribution of watermelon natural products at different levels of calculated hydrophilicity and lipophilicity. Molecules were counted in bins of one unit of AlogP. Those predicted to be hydrophilic are plotted in light blue with the strongest predicted hydrophilicity at the extreme left of the plot. Lipophilic compounds are in orange with the most lipophilic entities at the far right of the plot. (D) Compounds with identifiers in standard chemical repositories. Two hundred ninety-eight compounds have identifiers in all seven of these resources.
