Bottom Line: PTE administration (200 mg/kg) significantly suppressed body weight gain, liver weight, abdominal fat and triglycerides in serum and liver.Moreover, 4-week daily consumption of purple tea drink in humans improved obesity parameters compared to baseline, including body weight (79.9 ± 3.1 kg vs 80.8 ± 3.2, p<0.05), body mass index (BMI) (26.8 ± 0.6 vs 27.0 ± 0.6, p<0.05) and body fat mass (21.0 ± 1.4 kg vs 21.8 ± 1.5, p<0.01).In conclusion, PTE could control diet-induced weight gain by suppression of fat absorption and enhancement of hepatic fat metabolism.

ABSTRACT
A number of clinical trials have been completed using green tea and black tea to investigate their effect in controlling weight in overweight adults. The results of these investigations, however, have often been contradictory, with some trials reporting positive effects of tea supplementation and some trials reporting no effect. As a result, the use of these teas for weight loss is controversial. Purple tea is a variety of green tea developed in Kenya (called TRFK306), which in addition to certain tea constituents found in green tea, also contains anthocyanins. The major constituents in the leaves of purple tea are caffeine, theobromine, epigallocatechin (ECG), epigallocatechin gallate (EGCG) and 1,2-di-O-galloyl-4,6-O-(S)-hexahydroxydiphenoyl-β-D-glucose (GHG). We investigated the efficacy of purple tea extract (PTE) on diet-induced fat accumulation in mice. PTE administration (200 mg/kg) significantly suppressed body weight gain, liver weight, abdominal fat and triglycerides in serum and liver. Protein expression of carnitine palmitoyltransferase (CPT) 1A was also enhanced. In olive oil loaded mice, PTE (100 mg/kg) and caffeine (25 mg/kg) suppressed fat absorption. PTE (10 μg/mL) and GHG (10 μg/mL) also enhanced protein expression of CPT1A in HepG2 hepatoma. Moreover, 4-week daily consumption of purple tea drink in humans improved obesity parameters compared to baseline, including body weight (79.9 ± 3.1 kg vs 80.8 ± 3.2, p<0.05), body mass index (BMI) (26.8 ± 0.6 vs 27.0 ± 0.6, p<0.05) and body fat mass (21.0 ± 1.4 kg vs 21.8 ± 1.5, p<0.01). In conclusion, PTE could control diet-induced weight gain by suppression of fat absorption and enhancement of hepatic fat metabolism.

Effect of PTE on HFD-induced Bodyweight Gain in Mice. Each point represents mean with the S.E. (n=5-6). Asterisks denote significant differences from control at *p<0.05, **p<0.01, respectively. PTE (200 mg/kg) was given once a day for 17 days.

Figure 3: Effect of PTE on HFD-induced Bodyweight Gain in Mice. Each point represents mean with the S.E. (n=5-6). Asterisks denote significant differences from control at *p<0.05, **p<0.01, respectively. PTE (200 mg/kg) was given once a day for 17 days.

Mentions: The body weights of the control group exceeded those of normal group from day 7 to12 (Fig. 3). PTE (200 mg/kg) suppressed bodyweight gain from day 6 to 12 compared to control group. Final bodyweight in PTE group was significantly suppressed and the average body weight was same as normal group (Table 1). The weights of liver, epididymal fat and perirenal fat were also significantly suppressed by PTE. Regarding triglyceride content, serum TG and hepatic TG were also suppressed by PTE.
