  • There is great demand of nutraceutical secondary metabolites in the world so as to feed the population by improving agricultural production with new varieties of food crops but what is still more important is to add nutrition into the food. Physalis minima, plant of Solanaceae family, contain certain secondary metabolites which enhance the over all metabolic functions of the body. Withasteroids are one of such phytochemicals that are generally regarded as safe. These chemicals are almost monopoly of the plants of Solanaceae. The leaves, stem and roots of P. minima have been examined to yield several steroids, identification of which has been discussed in this paper. These withasteroids contribute to the potential nutraceutical and health function value since incorporation of withanolides in the diet may prevent or decrease the growth of tumors in humans.

  • To develop health-functional food ingredients for improvement of diabetes, we examined biological activities, including total contents of polyphenols and flavonoids, antioxidant activity, and inhibition of ${\alpha}$-glucosidase and pancreatic lipase activities of ethanol extracts from unripe fruit of Momordica charantia L. cultivated in Hamyang, Korea. Ethanol extracts were tested using different ethanol concentrations (0%, 30%, 50%, and 70%) and temperatures ($50^{\circ}C$ and $70^{\circ}C$). Experimental results showed that total polyphenol and flavonoid contents were achieved concentrations of 7.77 mg/g (tannic acid), 7.66 mg/g (gallic acid), and 10.66 mg/g (rutin). The hydroxyl radical scavenging, ABTS cation radical scavenging, and FRAP activities were 82.19%, 42.82%, and 0.19 under the same conditions, respectively. The highest inhibitory activities of ${\alpha}$-glucosidase and pancreatic lipase were achieved in the 70% ethanol extract at $70^{\circ}C$. These results will be useful for development of health functional foods for anti-diabetes using 70% ethanol extract from unripe fruit of bitter melon.

  • This study was performed to determine by the ability of the mixed culture of Lactobacillus bulgaricus and Streptococcus thermophilus to ferment Dioscorea opposita Thunb. (yam) and to evaluate the nutraceutical value of fermented yam. The titratable acidity (TA) value increased from 2 to 6% with increased concentrations in both raw yam and extracted lactic acid bacteria (LAB) fermented yam (LFY). The viable cell counts and the allantoin and diosgenin contents were higher in raw LFY at large concentrations (6%) than in extracted LFY samples at all fermentation periods up to 32 h. Based on these data, it confirmed that raw yam fermented by the combination culture of L. bulgaricus and S. thermophilus for various fermentation periods favors the symbiotic growth of LAB and results in higher nutraceutical content.

  • Obesity is a complex metabolic disorder that increases the risk for type 2 diabetes, hyperlipidemia, hypertension, and atherosclerosis. In this study, we evaluated the anti-obesity effects of Nelumbo nucifera leaf (NL) extract in 3T3-L1 adipocytes and obese db/db mice. NL extract among various parts (leaf, seed, and root) of N. nucifera most effectively reduced adipogenesis via inhibiting CCAAT enhancer binding protein α (C/EBPα) and peroxisome proliferator activated receptor γ (PPARγ) expression in 3T3-L1 adipocytes. The addition of NL extract enhanced the protein expression of uncoupling protein 2 (UCP2) as compared to untreated 3T3-L1 adipocytes. The oral administration of NL extract (100 mg/kg BW) significantly reduced food efficacy ratio, body weight, and face or total cholesterol level in obese db /db mice. Also, administration of NL extract significantly decreased adipocyte size and C/EBPα or PPARγ expression in the adipose tissues as compared with control (obese db/db mice). Therefore, our results suggest that NL extract among various parts of N. nucifera could be used as a functional food ingredient for the prevention and treatment of metabolic diseases including obesity and diabetes.

  • This study was designed to determine optimal extraction conditions of Chrysanthemum zawadskii (CZ) with high yield of bioactive compounds (linarin, polyphenols, and flavonoids) and improved in vitro activities. Ethanol extracts were examined at different concentrations (0, 30, 50, 70, and 95%) and temperatures (50 and $70^{\circ}C$). The recommended extraction conditions were 50% ethanol at $70^{\circ}C$ for 4 h, which gave the highest yield of linarin, polyphenols, and flavonoids. This extract appeared to have the greatest ABTS and DPPH radical scavenging activities (87.81% and 51.42% at $500{\mu}g/mL$, respectively) and ${\alpha}$-glucosidase (74.59%) and pancreatic lipase inhibitory activities (90.44%). As contents of linarin increased, antioxidative activity, inhibitory effects of carbohydrates and lipid absorption of CZ extracts increased as well. From these results, CZ extracts can be used in functional food industries.

  • The plant kingdom is considered to be a repository of modern medicine, attributable to their rich source of bio-active molecules and secondary metabolites. It is indeed the Nutraceuticals that enhance immunity and ensure a healthier life because of their prophylactic and therapeutic values. Over centuries, papaya [Caricaceae; (Carica papaya Linn.)] is a renowned nutritious and medicinal plant. Each part of the papaya like root, stem, leaf, flower, fruit, seed, rinds, and latex has its own nutraceutical properties. It serves as food, cooking aid, and Ethnomedicine to prevent and treat wide-range of diseases and disorders. It has also been traditionally used as appetite enhancer, meat tenderizer, purgative, medicinal acne, abortifacient and vermifuge. Over decades, a series of scientific attempts were made to authenticate the nutraceutical properties of papaya. These studies validated that the papaya has antiplasmodial, antitrichochramal, antitrichomonal, antidengue, and anti-cancer activities. They have also exhibited that papaya possesses antiseptic, antiparasitic, anti-inflammatory, antidiabetic, and contraceptive features, and it helps in the management of sickle-cell anaemia, HIV, heart diseases and digestional disorders too. Nevertheless, the responsible bio-active molecules and their mode of actions remain indistinct and imprecise, and this calls for further pharmacological and clinical research on them. Conclusively, papaya is one of the naturally gifted plants; though its nutraceutical properties as a food or as a quasi-drug are poorly understood or undervalued by people. Accordingly, this scrutiny, demand for instigation of public health awareness campaigns to promote papaya consumption, so that the society shall acquire optimal benefits of papaya and in turn prevent and alleviate various diseases and illness.

  • It is of utmost importance to feed the current world population by improving agricultural production with newer varieties of food crops, but what is still more important is to add nutrition into the food. Some of the plants, which are currently growing in the wastelands, contain certain phytochemicals which add to their neutraceutical and health value. These plants contain secondary metabolites which enhance the over all metabolic functions of the body. Withasteroids are one of such phytochemicals. These chemicals are almost exclusively found in plants of the Solanaceae family; one of which, Physalis minima, contains several with asteroids. The aerial parts and roots of P. minima have been found to contain several steroids, identification of which is been discussed in this paper. These with asteroids contribute to the functional value since incorporation of withanolides in the diet may prevent or decrease the growth of tumors in humans.

  • Resveratrol was incorporated into various combinations of single- and double-layer nanoemulsions, prepared by self-assembly emulsification and complex coacervation with chitosan, alginate, and ${\beta}$-cyclodextrin, respectively. Resveratrol nanoemulsions were composed of medium-chain trigacylglycerols (MCTs), $Tween^{(R)}$ 80, water, chitosan, alginate, and ${\beta}$-cyclodextrin. The corresponding mixtures were formulated for the purpose of being used as a nutraceutical delivery system. Resveratrol nanoemulsions were obtained with particle sizes of 10-800 nm, with the size variation dependent on the emulsification parameters including the ratio of aqueous phase and surfactant ratio. Resveratrol nanoemulsions were characterized by evaluating particle size, zeta-potential value, stability, and release rate. There were no significant changes in particle size and zeta-potential value of resveratrol nanoemulsions during storage for 28 days at $25^{\circ}C$. The stability of resveratrol in the double-layer nanoemulsions complexed with chitosan or ${\beta}$-cyclodextrin was higher, compared with the single-layer nanoemulsions.
