  • The purpose of this study was to examine the effects of dietary green tea powder supplementation on bone metabolism in streptozotocin-induced diabetic rats. Thirty-two male Sprague-Dawley rats (body weight $210{\pm}3g$) were divided into two groups, diabetic and non-diabetic groups. Each group was randomly divided into two subgroups which were fed with the control and 1% green tea powder diets. The serum and urine concentrations of calcium and phosphorus were determined. Serum osteocalcin and ALP and urinary DPD crosslinks value were measured in order to monitor bone formation and resorption. Bone mineral density (BMD) and bone mineral content (BMC) were estimated using PIXImus in the spine and femur. Body weight gain and FER were lower in the diabetic group than in the non-diabetic group regardless of diets. The serum concentration of calcium and phosphorus were not changed among all groups. Urinary calcium and phosphorus excretion were higher in the diabetic group than in the non-diabetic group regardless of diets; however, they were not significantly different by green tea powder intake. Serum alkaline phosphatase (ALP) was increased in the diabetic group than in thenon-diabetic group. Further, there were no significant differences in serum osteocalcin and urinary deoxypyridinoline crosslinks value among all groups. The levels of spine and femur bone mineral density of the diabetic group were significantly lower than that of the non-diabetic group. Within the diabetic group, spine BMD was significantly higher in rats fed with the green tea powder diet than in rats fed the control diet. Therefore, this study suggests that green tea powder has a beneficial effect on bone health, although it is not directly applicable to humans.

  • The ash content, mineral composition, total phenolics, antioxidant capacity, and neuroprotective effect of the antlers of deer fed with herb-incorporated feedstuff (HFS) or normal feedstuff (NFS) were comparatively evaluated. The contents of ash and mineral of the antler of deer fed with HFS were significantly lower than its counterpart. The ash and mineral contents of deer antlers decreased generally from the upper section toward the tip section. The ratios of Ca/ash, Ca/P, and Ca/Fe of antler of deer fed with HFS were lower than those of antler of deer fed with NFS. Antlers of deer fed with HFS had higher total phenolics, nitrite scavenging capacity, and antioxidant capacity than those of deer fed with NFS. Antlers of deer fed with HFS or NFS showed in vitro neuronal protection of PC-12 cells against oxidative stress in a dose-dependent manner, where antler of deer fed with HFS generally had higher cellular viability than NFS. These results above suggest that the incorporation of the medicinal herbal complex into feedstuff may improve the biological effects of deer antlers.

  • The effective components of Schisandra chinensis are lignans (schizandrins and gomisins), which have various physiological functionalities such as anti-cancer, anti-inflammatory, and antioxidant activities. This study was carried out to determine the different parts of fruits in Schisandra chinensis to elevate their usefulness. Schisandra chinensis was separated into skin (epicarp), pulp (mesocarp), and seeds, and raw Omija and hot-dried Omija (HDO) were used as control. The most abundant component was nitrogen free extract (6.88~56.70%) followed by crude lipids (1.65~19.04%). The main mineral was K (383.10~2,024.10 mg/100 g), except in seeds where P was the main mineral. The main lignan in all parts of fruit was schizandrin, and the highest content of schizandrin was 9.46 mg/g in dried seeds. Total lignan content was 25.97 mg/g and 14.97 mg/g in dried seeds and HDO, respectively. A total of 17 components of fatty acids in seeds and HDO were detected, of which linoleic acid (72.66~73.78%), oleic acid (14.78~17.39%), palmitic acid (2.88~3.54%), and capric acid (1.70~4.93%) were determined as the major components. Main lignans and fatty acids of Schisandra chinensis fruit contain mainly seeds. Therefore, it is more efficient to use seeds than pulp and extract of fruit itself to use the components of Omija.

  • Background: Angelica gigas Nakai is a perennial herb belonging to the family Umbelliferae. Its roots are utilized in traditional medicine. The aim of this study was to increase the yield of and the content of two indicator components (decursin and decursinol angelate) in A. gigas Nakai. Methods and Results: The roots of A. gigas Nakai were harvested 4-times from late August to late October in 2017. Two agents (trace element-TE, and plant hormone-HM) were applied 4 times at intervals of 2 weeks. The content of the two indicator components were analyzed by high performance liquid chromatography. The HM treatment showed the greatest increase in underground part yield and root diameter. The content of the two indicator components in the control (non-treatment) group was the highest in the underground part, but was higher in the aerial parts in the agent treatment group. After treatment with the agents, the content of the indicator components tended to decrease in the underground part. However, the total content of the indicator components in the two agent treatment groups exceeded the level of 6% set by the Korean Pharmacopoeia. Conclusions: The highest underground part yield was found in the HM treatment group, while the highest content of decursin and decursinol angelate were found in the control group. This study provides basic information for yield improvement in A. gigas.

  • Chrysanthemum boreale M. is an important medicinal plant that has been historically used in herbal medicine and in the health food throughout East Asia. This study was conducted to investigate the influence of abscisic acid (ABA) and salicylic acid (SA) on plant growth, mineral content and effective components, such as essential oil, amino acid and cumambrin A, by means in order to increase the productivity and the quality of flowerheads in the plant. Yields of flowerheads were increased by 12.7%, 21.7% and 15.5% by ABA, SA and both treatments, respectively, as compared with the control. Inorganic nutrient content was changed by PGRs; SA treatment was increased by nitrogen, phosphorus and magnesium content but decreased by potassium of C. boreale M. flowerheads. Total content of amino acid was increased by SA but decreased by ABA treatment. Essential oil content and yields were increased to 9.7% and 33.8% by SA treatment. Moreover, the content of terpene, monoterpenoids and sesquiterpenoids, were improved by ABA treatment, especially, germacrene-D content was increased by 39.1%, as compared to control. In addition, yields of cumambrin A, sesquiterpene compound exhibiting blood-pressure activity, increased in all PGRs treatments, but its concentration in the C. boreale M. flowerheads only increased by ABA and both treatment. The experiment suggests that PGRs using ABA and SA could increase the yields and quality of C. boreale M. flowerheads.

  • Background: Ginseng is a perennial crop grown for more than four years in the same place. Therefore, it is highly affected by the soil environment, especially nutrients in the soil. The present study was carried out to investigate to the influence of boron and iron concentrations on the physiological status, growth, and mineral uptake of ginseng to obtain the basic information for diagnosing a physiological disorder in ginseng plants. Methods and Results: The boron and iron concentrations were controlled at 3, 30, 150, 300 and 2, 20, 100, $200mg/{\ell}$, respectively. When treated with $150mg/{\ell}$ of boron, the ginseng plants showed yellowing or necrosis symptoms at the edge or end of their leaves. Compared with the $3mg/{\ell}$ treatment, the root weight decreased by 13 and 24% in the 150 and $300mg/{\ell}$ treatments, respectively. When treated with $20mg/{\ell}$ of iron, the ginseng plants showed yellowing between the veins of the leaves followed by the formation of brown spots. The root weight gradually decreased with increasing iron concentration. Approximately 55% decrease in root weight was observed upon treatment with $200mg/{\ell}$ of iron. Conclusions: The boron toxicity occurs in the leaves of ginseng at the boron concentration of approximately 1,900 mg/kg or more. The iron toxicity occurs at the iron concentration of approximately 120 mg/kg for leaves and 270 mg/kg for roots.
