In this study, fingerroot (Boesenbergia pandurata) and ginger (Zingiber officinale Roscoe) were extracted with water, 70% and 100% ethanol, respectively. The contents of polyphenols, flavonoids and ascorbic acid, antioxidant and antimicrobial activities of these extracts were measured. With respect to the polyphenol compound content, both fingerroot and ginger extract showed the highest in 70% ethanol extract, and the fingerroot extract showed a generally higher content than the ginger extract. The content of flavonoids, fingerroot and ginger extracts showed values of 1,247.14~1,259.93 ㎍%, and there was no big difference between extracts. The content of ascorbic acid was the highest in 100% ethanol extract in both fingerroot and ginger. Fingerroot extract was slightly higher than ginger extract in all extracts. The DPPH radical scavenging activity of fingerroot and ginger extracts showed the highest antioxidant activity in 100% ethanol extract, and fingerroot showed a slightly higher activity than ginger. The ABTS radical scavenging activity was high in 70% and 100% ethanol extracts of both fingerroot and ginger. In the activity between fingerroot and ginger extracts, ginger was higher in water extract and fingerroot was slightly higher in ethanol extract. Fingerroot and ginger extracts showed antimicrobial activity against Staphylococcus aureus and Bacillus cereus.

The skin plays a key role in protecting the body from the environment and from water loss. Cornified envelope (CE) and natural moisturizing factor (NMF) are considered as the primary regulators of skin hydration and barrier function. The CE prevents loss of water from the body and is formed by cross-linking of several proteins. Among these proteins, filaggrin is an important protein because NMF is produced by the degradation of filaggrin. Proteases, including matriptase and prostasin, stimulate the generation of filaggrin from profilaggrin and caspase-14 plays a role in the degradation of filaggrin. This study elucidated the effects of an ethanol extract of Boesenbergia pandurata (Roxb.) Schltr., known as fingerroot, and its active compound panduratin A on CE formation and filaggrin processing in HaCaT, human epidermal keratinocytes. B. pandurata extract (BPE) and panduratin A significantly stimulated not only CE formation but also the expression of CE proteins, such as loricrin, involucrin, and transglutaminase, which were associated with $PPAR{\alpha}$ expression. The mRNA and protein levels of filaggrin and filaggrin-related enzymes, such as matriptase, prostasin, and caspase-14 were also up-regulated by BPE and panduratin A treatment. These results suggest that BPE and panduratin A are potential nutraceuticals which can enhance skin hydration and barrier function based on their CE formation and filaggrin processing.

Boesenbergia pandurata (Roxb.) Schltr. has been reported to possess anti-oxidative and anti-inflammatory properties. The aim of this study was to investigate the effect of Boesenbergia pandurata extract (BPE) in a high-fat diet (HFD)-induced obese mice model. C57BL/6J mice were fed with either the high-fat diet or a 0.5% BPE-supplemented HFD for 8 weeks. The BPE-containing HFD significantly reduced body weight gain and the accumulation of visceral fat mass in mice model without altering the amount of food intake. Moreover, mice fed with BPE-containing HFD had lower concentrations of lipids in their blood, lower hepatic lipid accumulation, and lower serum leptin levels compared with the HFD-fed mice. RT-PCR analysis showed that the expression levels of peroxisome proliferators-activated receptor ${\gamma}2$ ($PPAR{\gamma}2$) and CCAT/enhancer binding protein ${\alpha}$ ($C/EBP{\alpha}$) genes in the epididymal fat tissue of mice fed the BPE-containing HFD increased 1.16- and 1.30-fold, respectively, compared to mice fed HFD only. In conclusion, BPE attenuated visceral fat accumulation and improved dyslipidemia in a mice model with HFD-induced obesity.

The objective of this study was to examine the effects of dietary Boesenbergia rotunda (L.) Mansf. rhizome extract on the growth performance, intestinal histology, digestive enzymes, hematological, and biochemical indices of hybrid catfish (Clarias macrocephalus × C. gariepinus). The phytochemicals and antioxidant activity of a methanolic extract from the rhizome of B. rotunda were also evaluated. Hybrid catfish, with an average weight of 5.24 ± 0.26 g, were given diets containing B. rotunda extract at concentrations of 0 (control), 250, and 500 mg/kg for a duration of 8 weeks. Upon completion of the trial, various factors were assessed including growth performance, intestinal histology, digestive enzymes, hematology, and biochemical indices. The presence of phenolics, saponins, alkaloids, flavonoids, steroids, and tannins was identified in the extract of B. rotunda. The inclusion of B. rotunda in the diet resulted in a substantial improvement in final weight, weight gain, specific growth rate, and average daily gain (p < 0.05). The fish that were given diets containing B. rotunda showed a significant increase in the activity of digestive enzymes in their intestines (p < 0.05). Fish that were fed B. rotunda diets exhibited improved histoarchitecture of intestines (p < 0.05). The experimental fish exhibited a considerable increase in white blood cells, red blood cells, hemoglobin, and hematocrit compared to the control group (p < 0.05). Fish that were fed B. rotunda diets showed a significant increase in serum glucose levels, whereas serum cholesterol levels decreased (p < 0.05). The study found that a diet containing 250 mg of B. rotunda/kg had the potential to improve the growth performance and physiological features of hybrid catfish.
