Background. Purple sweet potato leaves (PSPL) are widely grown and are considered a healthy vegetable in Taiwan. PSPL contain a high content of flavonoids, and the boiling water-extracted PSPL (PSPLE) is believed to prevent metabolic syndrome. However, its efficacy has not yet been verified. Therefore, we investigated the effect of PSPLE on adipocytes.Methods. The differentiated 3T3-L1 cells used in this study were derived from preadipocytes that were differentiated into adipocytes using an adipogenic agent (insulin, dexamethasone, and 3-isobutyl-1-methylxanthine); approximately 90% of the cells were differentiated using this method.Results. Treating the differentiated 3T3-L1 cells with PSPLE caused a dose-dependent decrease in the number of adipocytes rather than preadipocytes. In addition, treatment with PSPLE resulted in apoptosis of the differentiated 3T3-L1 cells as determined by DAPI analysis and flow cytometry. PSPLE also increased the expression of cleaved caspase-3 and poly ADP-ribose polymerase (PARP). Furthermore, PSPLE induced downregulation of interleukin-6 (IL-6) and tumor necrosis factor-α(TNF-α) gene expression in the differentiated 3T3-L1 cells.Conclusions. These results suggest that PSPLE not only induced apoptosis but also downregulated inflammation-associated genes in the differentiated 3T3-L1 cells.

Purple sweet potato leaves (PSPLs) are healthy vegetable that is rich in anti-oxidants. A solution of boiling water extract of PSPL (PSPLE) is believed to be able to prevent obesity and metabolic syndrome in the countryside of Taiwan, but its efficacy has not yet been verified. The purpose of this study was to investigate the possible anti-adipogenesis effect of PSPLE in vitro. PSPLE was used to treat the 3T3-L1 cells, and the effects on cell proliferation and adipogenesis were investigated. The results showed that PSPLE caused a dose-dependent decrease in the cell proliferation of 3T3-L1 preadipocytes, but did not alter the cell viability. In addition, PSPLE induced ERK inactivation in the 3T3-L1 preadipocytes. Furthermore, pre-treatment of confluent 3T3-L1 cells with PSPLE led to reduced lipid accumulation in differentiated 3T3-L1 cells. The inhibition of lipogenesis could result from the PSPLE-induced down-regulation of the expression of the C/EBPα and SREBP-1 transcription factors during 3T3-L1 adipocyte differentiation. These results suggest that PSPLE not only inhibits cell proliferation at an early stage but also inhibits adipogenesis at a later stage of the differentiation program.

The administration of high-fat diets can increase the body's lipid level and damage the organs. Purple sweet potato leaf (Ipomoea batatas L.) was reported as an antioxidant against free radicals. This study aimed to observe the sweet potato leaf extract's activity on decreasing lipid profile and hepatoprotective effect in high-fat diet fed rats. The treatment animals were divided into five groups, namely normal control, high-fat diet (HFD) control, the treatment group of purple sweet potato leaf extract (SPLE) doses 100 mg/kg BW, 200 mg/kg BW and 400 mg/kg BW which fed with high-fat diet for 14 days and SPLE for 28 days. After treatment was completed, the blood was collected for the detection of cholesterol, triglyceride, serum glutamic oxaloacetic transaminase (SGOT), and serum glutamic pyruvate transaminase (SGPT). After that, the animals were sacrificed, and a liver histopathology observation was conducted using Haematoxylien and Eosin staining. The result showed a significant decrease in cholesterol and triglyceride levels (p≤0.05) compared to the negative group in all treated groups. The SGOT and SGPT enzymes in all of treatment groups were also found to decrease compared with HFD control. The result was confirmed by the histopathological observations. The finding suggested the potency of SPLE for antihyperlipidaemic and hepatoprotective agent.
