A total of 184 Stevia leaf samples taken from herbarium specimens, representing 110 species and 121 taxa, were screened organoleptically for their taste sensation. Fragments of a 62-year-old leaf of S. rebaudiana exhibited a potent and prolonged sensation of sweetness, thereby indicating the stability of its sweet ent-kaurene glycoside constituents to drying, preservation, mounting and storage. No other leaf samples exhibited an intensity of sweetness equivalent to that of S. rebaudiana, though 18 species and varieties were considered to exhibit a sweet taste. These taxa appear to be promising candidates for future phytochemical investigation for new and known ent-kaurene glycosides.
从植物标本馆标本中采集了总共184份甜叶菊叶片样本，代表110个物种和121个分类单元，通过感官对其味觉进行了筛选。一株62年生的甜叶菊叶片碎片呈现出强烈且持久的甜味，这表明其甜贝壳杉烯糖苷成分在干燥、保存、装裱和储存过程中具有稳定性。没有其他叶片样本呈现出与甜叶菊相当的甜度，不过有18个物种和变种被认为具有甜味。这些分类单元似乎是未来针对新的和已知的贝壳杉烯糖苷进行植物化学研究的有前景的候选对象。
