Natural product substances have historically served as the most significant also be prepared by source of new leads for pharmaceutical development. They can chemical synthesis(both semisynthesis and total synthesis) and have played a important role in the field of organic chemistry by providing synthetic targets. Rcently, they have also been extended for commercial purpose to refer to medicinal products, health functional foods, dietary supplements and cosmetics from natural sources. A large number of currently prescribed drugs have been either directly derived from or inspired by natural products. However, with the advent of robotics, bioinformatics, high throughput screening(HTS), molecular biology-biotechnology, combinatorial chemistry, in silico(molecular modeling) and other methodologies, the pharmaceutical industry has largely moved away from plant derived natural products as a source for leads and prospective drug candidates. The strategy for natural prduct industry is now changing from drug approaches to health foods by identifying effective natural products as preparations. In Korea, a lot of development of natural product based drugs have been done, but very few on health functional foods. The concept of natural product based health foods is not active components as lead compounds but standardized extracts or preparation mixed with other medicinal plants. The representative material has been recently known to be a standardized ginseng extract "Ginsana G 115" developed by Swiss Pharmaton company. The purpose of this presentation is to underline how natural products research continues to make significant contributions in the domain of discovery and development of new health functional foods. It is proposed to present the development of high value added health food or health functional foods through scientific investigation on efficacy and standardization of new materials form natural products.

The health function food law has been carried into effect from January 31, 2004 just after the proposal of 'a draft of a proposed law concerning the health function foods for the promotion of a nation health' on November 29, 2000 in Korea. After enforcement of health functional food law, there have been difficult market penetration with overall stagnancy of business activities and the current of health functional food within the country divided two groups. In standardized health functional foods the present condition, nutrition supplementary products (938 items) and red ginseng products (351 items) are prevalent and total 32 products are registered containing lactobacilli (297 items), glucosamine (295 items), ginseng (182 items), yeast(136 items) so on. In 2005, five products (products containing green tea extract, soybean protein, plant sterol, fructooligo sugar and Monascus sp. products are newly notified and raw material or component of total 21 products containing xylitol, teanin extract, sardine peptide are recognized as individual authorized health functional foods. Efficacies of ginseng are studied in many-sided researches but benefits of the ginseng in the health functional food law limited to 3 items (staminaresume, immune enhancement, nourishment robustness). To enlarge functionalities of ginseng it needs raw material and ingredient approval through data application to Korea Food and Drug Administration and this procedure acts as barrier of the functional food development in the ginseng industry. It is necessary to develop the authorized health functional foods for leading health functional food market in the future.

There is a growing consumer preference for self-medication, which has resulted in the growth of the Korean functional food market to \1.5 trillion in 2014. Functional foods that can modulate immune responses and enhance liver health are in the top 2 product-specific health functional food categories. The aim of this project was to develop and commercialize new health functional foods incorporated with Cordyceps militaris. Cordyceps genus includes about 400 species, many of which have been used as traditional medicines for many years in Asian countries. C. militaris belongs to the class Ascomycetes and has been used extensively as a crude drug and tonic food in East Asia. Owing to the various physiological activities of its main active constituent, cordyceptin, C. militaris is currently being used for multiple medicinal purposes. Recently, many studies have tried to elucidate the pharmacological mechanisms underlying the activities of Cordyceps spp., which include immune activation, anti-inflammatory, anticancer, and antiviral effects. After continuous attempts and research toward industrialization, C. militaris cultivated using brown rice was developed into a product by a standardized process and mass-cultivating system. It was successfully introduced into the market and was approved as a functional food ingredient for the first time in Korea. Based on this information, C. militaris containing functional food product for strengthening the immune system was released in August 2014 under the brand name "Dongchoong Ilgi." Dongchoong Ilgi is potentially beneficial for improving immune and liver functions and may enhance both the convenience and effectiveness of health functional foods taken by healthy people and patients with minor illness. In addition, the results of our study may be applicable for the development of health functional foods that could lower the risk of diseases such as the common cold and cancer.

Ophiocordyceps sinensis is a natural fungus that has been valued as a health food and used in traditional Chinese medicine for centuries. The fungus is parasitic and colonizes insect larva. Naturally occurring O. sinensis thrives at high altitude in cold and grassy alpine meadows on the Himalayan mountain ranges. Wild Ophiocordyceps is becoming increasingly rare in its natural habitat, and its price limits its use in clinical practice. Therefore, the development of a standardized alternative is a great focus of research to allow the use of Ophiocordyceps as a medicine. To develop an alternative for wild Ophiocordyceps, a refined standardized extract, CBG-CS-2, was produced by artificial fermentation and extraction of the mycelial strain Paecilomyces hepiali CBG-CS-1, which originated from wild O. sinensis. In this study, we analyzed the in vitro immune-modulating effect of CBG-CS-2 on natural killer cells and B and T lymphocytes. CBG-CS-2 stimulated splenocyte proliferation and enhanced Th1-type cytokine expression in the mouse splenocytes. Importantly, in vitro CBG-CS-2 treatment enhanced the killing activity of the NK-92MI natural killer cell line. These results indicate that the mycelial culture extract prepared from Ophiocordyceps exhibits immune-modulating activity, as was observed in vivo and this suggests its possible use in the treatment of diseases caused by abnormal immune function.

Changing health awareness has had an important effect on the functional food industry and is creating greater market opportunities. Unfortunately, there is no statement on functional dairy products in the Processing of Livestock Products Act. As a result, there is confusion in the market and legal difficulties with regard to the advertising of functional dairy products. This study was carried out to improve the current standardization of functional dairy products by comparing the domestic Health/Functional Food Act with the Japanese Health Promotion Law, and by investigating scientific data and articles from various literature and the Internet. In Japan, the Ministry of Health, Labor, and Welfare (MHLW) officially presented the Food with Health Claims (FHC) system that consists of Food with Nutrient Function Claims (FNFC), and innovated Food for Specified Health Uses (FOSHU). In 2005, the FOSHU system was changed to include several new subsystems: Current, Standardized, Reduction of disease risk, and Qualified FOSHU. Finally, to manufacture FOSHU, scientific evidence pertaining to such products must be examined by MHLW. Since FNFC was allowed, only 12 vitamins, ${\beta}-carotene$, and five minerals were approved, though without scientific evidence of efficacy. The Korean Health/Functional Food Act requires that health/functional foods (HFFs) be marketed in measured doses. There are two types of HFFs: generic and product-specific. There are 67 ingredients listed in the act for generic HFFs, and if an HFF has a new active ingredient, it is considered a product-specific HFF. Product-specific HFFs must be approved by the Korean Food and Drug Administration (KFDA). With the present standards, it is impossible to label and advertise functional dairy products with health/functional claims. Government agencies must cooperate to solve this problem, and standardization should be carried out by considering existing health/functional products and claims/indications from other countries.
