In Ayurvedic medicine, for example, plants are often administered daily as decoctions for various practical reasons, including the availability of water and the concurrent need of sterilization for both herbal drugs and solvent, an hygienic prophylaxis that must not be overlooked when operating in some geographic and socio-cultural contexts.

Of resveratrol metabolites and estrogenic activity

The road from the food source to the active phytochemical is a long and tricky one. Take wine and resveratrol: there is likely too little of this stilbene in wine to extert its purported health benefits through dietary intake. Moreover, it is generally studied as the unconjugated aglycone, while following intestinal absorption in humans, trans-resveratrol and its glucoside -which are naturally present in wine and other food sources- are converted to sulphate and glucuronide metabolites. At present, few studies have been made on these substances and while an estrogenic activity has previously...

From a fruit to a commercial juice: the phytochemical profile of pomegranate

So, we like pomegranate a lot: it’s tasty, healthy and promising. Pomegranate fruit and pomegranate juices have recently received great attention for their health benefits, mainly due to their high polyphenols content and the related antioxidant capacity. Nevertheless, the pomegranate processing and its effects on juice composition has been only little investigated. In our latest paper, expanding our expertise on pomegranate research, we considered two important steps of pomegranate juice production, the separation of arils from peels (cleaning) and the enzymatic clarification of the...

Predicting the functional role of essential oils

Many biological activities are usually ascribed to essential oils, and most of them are related to potential benefits in different areas of human interest: food and cosmetics preservation, funcional role in toiletries, bioactive ingredients and so on. In our latest paper on this regard, different lavender essential oils were evaluated in order to develop a predictive method based on GC/GC-MS and multivariate data analysis, starting from a limited number of parameters. This approach could represent a useful tool to suggest which phytochemical profile could offer the best overall results in...
