Influence of the aleanolic acid glycosides from Silphium perfoliatum L. (silphioside B, C, E and G) and their progenins on the amylase activity and total protein content in wheat seedlings was studied. Treatment of the Triticum aestivum L. seeds with 1-10 microM water solutions of mono- and diglycosides (mono- and bisdesmosines) elevated the alpha-amylase and total amylase activities in seedlings. Silphioside E containing three glucose moieties in its molecule did not change alpha-amylase activity, but it did if bis-triglycoside acetylated carbohydrate (as in silphioside C). Effects of 5-10 microM solutions of the active glycosides was comparable with that of exogenous gibberellin A3 and 6-benzylaminopurine.
研究了串叶松香草中的齐墩果酸苷（串叶松香草苷B、C、E和G）及其衍生物对小麦幼苗淀粉酶活性和总蛋白含量的影响。用1-10微摩尔/升的单糖苷和二糖苷（单和双去甲猪毛菜碱）水溶液处理普通小麦种子，可提高幼苗中的α-淀粉酶和总淀粉酶活性。分子中含有三个葡萄糖部分的串叶松香草苷E不会改变α-淀粉酶活性，但双三糖苷乙酰化碳水化合物（如串叶松香草苷C）则会改变。5-10微摩尔/升活性糖苷溶液的作用与外源赤霉素A3和6-苄基腺嘌呤相当。
