본 연구는 산수유 고유의 붉은색과 신맛, 쓴맛을 유지하기 위해 당 함유량을 줄인 산수유잼을 제조하였다. 고형분 농도가 일정한 산수유 퓨레를 제조한 후 이를 이용하여 저당 산수유잼 제조 배합비를 조사하였다. 산수유 퓨레는 과육 무게의 동량 멸균증류수를 첨가하여 제조하였으나 수분 함량은 20~30% 정도만 증가하였다. 펙틴 함량은 0.14%로 매우 낮게 나타나 잼 제조 시 겔화제의 첨가가 필요하였다. 퓨레는 과육에 비해 당도가 30% 수준으로 감소하였으나 pH는 차이가 없었다. 펙틴 첨가로 인한 잼의 pH 변화는 없었다. 퓨레의 L값, a값 및 b값 모두 성숙과 퓨레가 완숙과 퓨레에 비하여 높게 나타났다. 또한 잼 제조 시 성숙과의 함량이 증가할수록 L값, a값 및 b값 모두 증가하였다. 기계적 경도는 펙틴 함량이 증가할수록, 완숙과의 함유량이 증가할수록 산수유잼의 gel strength 및 hardness가 증가하였다. 산수유 성숙과 및 완숙과 퓨레의 DPPH 라디칼 소거능은 100 ppm 농도에서 각각 50.96%, 47.92%의 소거 활성을 보였으며, 산수유잼은 1,000 ppm 농도에서 41.24~49.98%의 소거 활성을 보였다. 총 폴리페놀 함량은 92.70~158.52 mg GAE/g으로 완숙과의 첨가량이 증가할수록 폴리페놀 함량은 감소하는 경향으로 산수유 과육이 농후해지면서 폴리페놀 함량은 감소하였다. 전반적인 기호도 평가에서는 펙틴 2.0%가 5.43, 성숙과 및 완숙과를 동량 첨가했을 때 5.03으로 가장 높은 점수를 보였다. 이와 같은 결과를 통해 건피에 국한되었던 산수유 가공품이 생과를 활용한다면 다양한 제품 개발이 가능할 것으로 생각된다.

In the recent, increased concern has been focused on the pharmacology and clinical utility of herbal extracts and derivatives as a drug or adjunct to chemotherapy and immunotherapy. Here we investigated the role of the extract of Anethi Fructus in the expression of inflammatory mediators, surface molecule, and related receptors in vitro. In murine macrophage RAW 264.7 cells and peritoneal macrophages of C57BL/6N mice, water extract of Anethi Fructus increased the production of secretary tumor necrosis factor (TNF)-a and Nitric oxide (NO), and the expression level of CD14, LPS co-receptor and CD86, co-stimulatory molecule compared to negative natural extract ex vivo. The water extract of Anethi Fructus increased the production of interferon (IFN)-g from splenocytes. Also, water extract of Anethi Fructus increased ConA-induced cell proliferation. These results suggest that water extract of Anethi Fructus may enhance the immune response through immune modulation of macrophage and lymphocytes.

By analysing the benzo(a)pyrene concentration using HPLC-FLD and LC-MS/MS, pollution levels of herbal medicines without permitted benzo(a)pyrene specification were investigated. Average benzo(a)pyrene concentrations were 38.30, 37.46 and 21.22 ㎍/kg for Amomi Tsao-ko Fructus, Mume Fructus and Coptidis Rhizoma, respectively, which are 4 to 7 times higher than maximum permitted benzo(a)pyrene concentration of Rehmanniae Radix Preparata and Rehmanniae Radix, i.e. 5.0 ㎍/kg. Proportion of detected samples exceeding 5.0 ㎍/kg benzo(a)pyrene concentration was 22% for Cimicifugae Rhizoma and Scrophulariae Radix, 44% for Forsythiae Fructus, 67% for Mume Fructus, 100% for Amomi Tsao-ko Fructus and Coptidis Rhizoma, and collectively 29% (36 out of 125 samples) in average. In terms of risk characterization results, human exposure of benzo(a)pyrene were 7.96, 3.49 and 1.61 ng/kg b.w./day and the margin of exposure(MOE) were 1.25 × 10⁴, 2.86 × 10⁴ and 6.20 × 10⁴ for Mume Fructus, Amomi Tsao-ko Fructus and Coptidis Rhizoma, respectively. MOE banding of those herbal medicines was categorized to 'low concern'. However, considering that human exposure of benzo(a)pyrene for food is legislated to 1.4~2.5 ng/kg b.w./day, it was urgent to set up the guideline of benzo(a)pyrene in herbal medicines.

Objectives : The objective of the paper was to study cutting method of Gardeniae frutus, that tends to show symptom of separations in a packing, in accordance with the comparison experiment of quantification and antioxidant effect proceed with the intact Gardeniae fructus(Gf), seed of Gardeniae fructus (Gs) and the pericarp of Gardeniae fructus (Gp) separately. Methods : The Gf, Gs, and Gp were extracted using 80% MeOH, followed by quantizing geniposide contained in each group. A MTT assay was conducted and ROS generation and NO production were measured for comparing its antioxidant effect. Results : As a result of quantizing geniposide contained in the Gf, Gp, and Gs, respectively, the geniposide content was shown to be the highest in the Gs. MTT assay showed that no cytotoxicity was observed in the groups treated with Gf, Gp, and Gs, respectively, at a dose of 500 ${\mu}g/ml$. The ROS generation was shown to have more significantly decreased in the group pretreated with Gf 500 ${\mu}g/ml$ than in the group treated with LPS. The NO level was shown to have more significantly decreased in the group pretreated with Gp 500 ${\mu}g/ml$ than in the group treated with LPS. Conclusion : As the geniposide content and antioxidant effect of Gf varies according to its each part, it is recommended that Gf should be distributed as an intact form other than segregation in packing.
