Substances found in hop leaves could help fight dental disease

Natural Health News – Hop that are discarded during the brewing leaves they are full of antioxidants polyphenols that may protect against dental disease, according to Japanese researchers.

In a new study Journal of Agricultural and Food Chemistry , Yoichi Shibusawa of the Tokyo University of Pharmacy and Life Sciences and colleagues say his previous research suggested that proanthocyanidins antioxidant jump ( Humulus lupulus ) leaves known as bracts, can help fight gum disease and tooth decay.

extract bracts stopped the bacteria responsible for these dental conditions sticking to surfaces and prevented the release of some bacterial toxins , suggesting “a possibility the beneficial owner and the industrial use of hop bracts that are not used for brewing beer. ”

In his latest research that has identified various substances present in the extract of the bracts that could be responsible for these health benefits.

going to lose?

Each year the EU, which is responsible for 50% of world production, about crops 57,000 tons of hops . US farmers harvested about 23,000 tons. China and Ethiopia are also important hop producers

But the bracts are not used for making beer and generally discarded (although it has been suggested that could be used as a component of animal feed or as soil improvers ).

Therefore, there is potentially a lot of bracts that will waste that could reused and previous studies have confirmed that these are higher in antioxidants than tea.

However, very few of the potentially hundreds of compounds in the bracts have been reported. Tanaka’s group decided to investigate what substances in these leaves could cause such health effects.

New compounds

Using a laboratory technique called chromatography, found three new compounds, a compound already known that first identified in plants and 20 compounds and acquaintances who met for the first time in hops. In all over 100 different components were isolated form a sample of bracts

were also found

bracts to contain substantial amounts of proanthocyanidins, which are antioxidants healthy.

The team suggests that new studies now the biological effects of the compounds newly identified in order to maximize the industrial potential of hop bracts are needed.
