Malformin was identified, by its biological activity and chromatography, in acetone extracts of the outer scales of onion bulbs infected with Aspergillus niger. Malformin was not detected in tissue underlying the infected areas or in the central portions of the bulbs, nor was malformein liberated from extracts or extracted tissues after reduction with zinc in acetic acid. This is the first report of naturally occurring malformin.
通过生物活性和色谱法，在感染黑曲霉的洋葱鳞茎外层鳞片的丙酮提取物中鉴定出了缩苹果酸。在感染区域下方的组织或鳞茎的中心部分未检测到缩苹果酸，在用锌在乙酸中还原后，提取物或提取的组织中也未释放出缩苹果素。这是关于天然存在的缩苹果酸的首次报道。
