Herbal water is obtained from steam-distillate of herbs. Some of them, e.g. rose, rosemary and orange flower are used as natural origin perfume. Most of them, however, have usually been discarded without any use. In order to develop a new usage of the herbal water as food and cosmetics from the viewpoint of medical functions, we examined collagenase and tyrosinase inhibitory activities related to the skin by 95 species of herbal water in vitro.The contents of phenolic compounds were measured by BCA test, respectively.As a result, each herb-water derived from Clary Sage (Salvia sclarea L.), Jew's marrow (Corchorus olitorius) and Lemon glass (Cymbopogon citrutus) showed prominent collagenase inhibitory activities, and those of Rose (Hybrid perretual), Sage (Salvia officinalis L.) and Lemonberm (Melissa officinalis L.) moderate tyrosinase inhibitory activities. Phenolic compounds were detected in herbal waters from almost all species, and especially the waters from so-called odorous plants such as laurel (Laurus nobilis), African blue basil (Ocimum basilicum uar.) and bergamots (Monada fistulosa mentaefolia, Monada didima) contained larger amounts of phenolic compounds than in others.From the calculation result of hydration energy and LogP of certain compounds in essential oil and herbal water with the computer, it was suggested that the compounds with high hydration energy have shifted from the essential oil to the herbal water. In addition, that new components generated it in the herbal water were detected by gas chromatography.If the correlation of the individual herbal water might be relized, the quality of the water may simply be evaluated and the herbal water can be expected to use widely in the field of medicine and cosmetics. |
