BelSU Scientists Discover Valuable Compounds in Aggressive Weed Sprouts

RIA Novosti recently reported on the findings of this study, which focused on the levels of resveratrol – a well-known antioxidant – in the leaves of this invasive plant.

Japanese knotweed (Reynoutria japonica), native to the Far East, is recognized as one of the most dangerous invasive species by the International Union for Conservation of Nature. Its robust root system can damage asphalt, undermine building foundations, and compromise light structures. The plant’s powerful shoots grow at an astonishing rate of 1 cm every three days, reaching heights of up to 3 meters. In Japan and the Korean Peninsula, knotweed is not only used in cooking but also in traditional medicine for treating various ailments.

Under the guidance of Dr. Viktor Deineka, a Professor of Chemical Sciences, scientists from BelSU’s Department of General Chemistry investigated the properties of Japanese knotweed sprouts found in Belgorod. Their analysis revealed that the vibrant red color of the leaves is due to a high concentration of anthocyanins – natural pigments known for their antioxidant benefits.

‘The colour of the leaves is linked to the accumulation of anthocyanins based on cyanidin, which are believed to have preventive effects against cardiovascular diseases and certain types of cancer,’ explained Professor Deineka.

The researchers specifically examined young knotweed sprouts, where they discovered a significant concentration of piceid, a form of resveratrol recognized for its anti-inflammatory and neuroprotective properties. The results suggest that the leaves of Japanese knotweed sprouts could serve as a promising source of biologically active compounds. As Dr. Deineka noted, the shift from synthetic drugs to natural alternatives represents a positive trend in contemporary science.
