  A facile method for the preparation of α-methylene-γ-butyrolactones from tulip tissues by enzyme-mediated conversion

  摘要：

  We developed a facile method of enzyme-mediated conversion of 6-tuliposide to alpha-methylene-gamma-butyrolactone (tulipalin). We used a tuliposide-converting enzyme for the conversion of 6-tuliposides extracted from tulip tissues into the corresponding tulipalins in high yields within 2 h at pH 7.0. The resulting tulipalins were selectively extracted by using several organic solvents. (C) 2009 Elsevier Ltd. All tights reserved.

  The present invention relates to a method for the production of sugars, in particular glycosides, from bulbs, comprising the steps of a) inducing gummosis in a bulb;b) optionally separating the gum from the bulb to obtain the gum;c) optionally extracting the sugar from the gum under polar or semipolar conditions.
