  Synergy Effect of Sodium Acetate and Glycosidically Bound Volatiles on the Release of Volatile Compounds from the Unscented Cut Flower (Delphinium elatum L. “Blue Bird”)

  摘要：

  Many modern floricultural varieties have lost their scent during traditional breeding programs. The factors that result in the nonscent emission of some cut flowers remain unclear. The objective of this study was to investigate whether the nonscent emission is due to one of the factors, the lack of suitable substrates (or precursors of scent compounds). Using solid-phase microextraction and dynamic headspace volatile sampling techniques, the supplement of nonvolatile compounds such as 2-coumaric acid glucoside to the unscented cut flower such as Delphinium elatum L. "Blue Bird" enhanced the emission of scent from the flower, which was sufficient for detection by the human olfaction. Interestingly, compared with feeding with each compound, the combination of sodium acetate and 2-coumaric acid glucoside showed the synergy effect on enhancement of coumarin, a cherry leaf-like scent emission from the flower, which is due to one of factors that sodium acetate enhanced the activity of beta-glucosidase being involved in the formation of the scent compound. These results suggest that some enzymes responsible for the formation of floral scents indeed occur in the unscented flowers such as Delphinium elatum L. "Blue Bird", and the non- or low-scent emission of the flowers are due to the lack of suitable substrates.

  A plant growth supporting body containing at least one of bactericide, antimold, insecticide and deodorant, and having a coating layer made of air-permeable, water-permeable and noncorrosive material for wrapping substantially occlusively the soil therein. This body does not allow the soil to leak out, prevents the growth of microbes and injurious insects, suppresses the soil smell to give a feeling of cleanness, improves the keeping quality of plants, and is suitable as an ornamental.

  一种植物生长支撑体，含有杀菌剂、防霉剂、杀虫剂和除臭剂中的至少一种，并具有由透气、透水和非腐蚀性材料制成的涂层，可将土壤基本包覆其中。本体不允许土壤渗漏，防止微生物和有害昆虫的生长，抑制土壤气味，给人以清洁的感觉，提高植物的保存质量，并适合作为观赏植物。

  The present invention provides a sustained-release aromatic, characterized in that the aromatic comprises at least one perfume derivative as an active component selected from glycosides of perfumes, phosphoric acid ester derivatives of perfumes, amino acid derivatives of perfumes and carboxylic acid derivatives of perfumes, and contains no enzyme or acid which decomposes the perfume derivative, wherein the perfume derivative is decomposed by bacteria usually present on the skin or yeast to release a perfume component to exhibit aroma. The present invention also provides a method for the detection of micro-organisms using the aforesaid sustained-release aromatic. As the sustained-release aromatic of the present invention releases a perfume component only when it is decomposed by micro-organisms such as bacteria usually present on the skin or yeast, the amount of perfumes to be used can be extremely reduced. The sustained-release aromatic of the present invention is also excellent in keeping aroma. The stability with the passage of time of the sustained-release aromatic of the present invention is much better than that of the prior art because the perfume component is contained in the form of derivative. The sustained-release aromatic of the present invention is useful for applications on the skin, head skin or hair of human beings or animals, on clothes, or in drinks and foods, or as an indicator for detecting micro-organisms.

  本发明提供了一种缓释芳香剂，其特征在于该芳香剂包含至少一种香水衍生物作为活性成分，该香水衍生物选自香水的糖苷、香水的磷酸酯衍生物、香水的氨基酸衍生物和香水的羧酸衍生物，并且不含有分解香水衍生物的酶或酸，其中香水衍生物被通常存在于皮肤上的细菌或酵母分解，释放出香水成分，从而表现出芳香。本发明还提供了一种使用上述缓释芳香剂检测微生物的方法。由于本发明的缓释芳香剂只有在被通常存在于皮肤或酵母上的细菌等微生物分解时才会释放香水成分，因此可以大大减少香水的用量。本发明的缓释芳香剂在保持芳香方面也非常出色。由于香水成分以衍生物的形式存在，本发明的缓释芳香剂随着时间推移的稳定性比现有技术要好得多。本发明的缓释芳香剂可用于人或动物的皮肤、头皮或毛发、衣服、饮料和食品，或用作检测微生物的指示剂。

  日期：1994.8

  2-Phenylethyl alpha-glucoside was synthesized from 2-phenylethanol and alpha-D-glucose in the presence of p-toluenesulfonic acid monohydrate at 75 degrees C and was isolated by continuous extraction, during which hexane was used to remove the excess 2-phenylethanol and then ethyl acetate was used to isolate the product. The spectral data including IR, H-1 NMR, C-13 NMR, and MS of this compound are presented.
