Abstract

Background

Pu-erh tea, a dark tea from China, is classified into raw and ripened types. Both have significant anti-obesity effects. Polyphenols are among their major bioactive components. This study aimed to explore the anti-obesity properties and mechanisms of raw (R-TP) and ripened (F-TP) Pu-erh tea polyphenols.

Results

The results showed that R-TP and F-TP significantly reduced body weight, improved insulin resistance, and enhanced glucose and lipid metabolism in high-fat-diet (HFD)-induced obese mice. Mild differences were observed in their impact on fat metabolism, carbohydrate metabolism, and inflammation levels. Both R-TP and F-TP were able to restore the disrupted intestinal flora caused by HFD treatment, returning them to a composition and levels similar to those of normal mice. Interestingly, the gut microbiota of all the mice could be reclassified into three enterotypes (enterotype Type-1, Type-2, and Type-HFD). Lactobacillaceae predominated in Type-1. Lactobacillaceae, Muribaculaceae, and Lachnospiraceae were the most common in Type-2. Type-HFD was primarily composed of Atopobiaceae, Lachnospiraceae, Lactobacillaceae, Ruminococcaceae, and Erysipelotrichaceae. The small differences in the effects of R-TP and F-TP may be due to variations in enterotypes.

Conclusion

These findings indicate that R-TP and F-TP can alleviate obesity by regulating the enterotype of gut microbiota, suggesting that they possess the potential for application in the treatment of obesity and the development of anti-obesity agents. © 2025 Society of Chemical Industry.

期刊介绍： The Journal of the Science of Food and Agriculture publishes peer-reviewed original research, reviews, mini-reviews, perspectives and spotlights in these areas, with particular emphasis on interdisciplinary studies at the agriculture/ food interface. Published for SCI by John Wiley & Sons Ltd. SCI (Society of Chemical Industry) is a unique international forum where science meets business on independent, impartial ground. Anyone can join and current Members include consumers, business people, environmentalists, industrialists, farmers, and researchers. The Society offers a chance to share information between sectors as diverse as food and agriculture, pharmaceuticals, biotechnology, materials, chemicals, environmental science and safety. As well as organising educational events, SCI awards a number of prestigious honours and scholarships each year, publishes peer-reviewed journals, and provides Members with news from their sectors in the respected magazine, Chemistry & Industry . Originally established in London in 1881 and in New York in 1894, SCI is a registered charity with Members in over 70 countries.
