This study aimed to investigate the effects of Centella asiatica powder on the quality characteristics and storage stability of goat meat Tteokgalbi. The goat meat Tteokgalbi samples were prepared with four different quantities (0, 0.5, 1, and 1.5%) of Centella asiatica powder. The moisture content of the samples containing Centella asiatica powder was significantly lower than that of the control (p<0.05). The protein content of the samples containing Centella asiatica powder was significantly higher than that of the control (p<0.05). As the proportion of Centella asiatica powder increased, the pH, L^*, and a^* values of the uncooked and cooked samples decreased (p<0.05). The water holding capacity and the cooking yield of the uncooked and cooked samples were higher in the samples containing Centella asiatica powder than in the control (p<0.05). Also, with the increasing amounts of the Centella asiatica powder, the thiobarbituric acid reactive substance (TBARS) levels decreased. The 1-1.5% Centella asiatica powder group showed lower levels of volatile basic nitrogen (VBN) than the other groups as per the assay (p<0.05). The results indicate that Centella asiatica powder could enhance the quality characteristics and storage stability of goat meat Tteokgabi.

Periodontal regeneration requires the migration and proliferation of gingival fibroblasts and periodontal ligament cells. These cellular events are influenced and regulated by growth factors and some drugs. The purpose of this study is to examine the effect of Rhizoma coptidis and Centella asiatica extracts on human gingival fibroblasts. Gingival fibroblasts were primarily cultured from extracted premolar with non-periodontal diseases. Cells were cultured with ${\alpha}-MEM$ at $37^{\circ}C$, 5% $CO_2$, 100% humidity incubator for 2 or 3 days, as a measure of cell proliferation potential, it was examined that the DNA synthesis using $[^3H]-thyrnidine$ incorporation, the cell numbers (with or without dye), and cell viabilities. Rhizoma coptidis is increased the proliferation of gingival fibroblasts at concentration of $10^{-9}g/ml$, but Centella asiatica is decreased the proliferation at all concentrations. This study demonstrated that Rhizoma coptidis is a potential mitogen for human gingival fibroblasts in vitro, and we can expect the usefulness of this drug in periodontal regeneration.

Effects of titrated extract of Centella asiatica (TECA) and epidermal growth factor (EGF) isolated from the urine of pregnant horse on the proliferation of human epidermal keratinocyte in culture were studied. An increase in the number of keratinocyte was observed with the treatment of TECA at the concentration ranges from 1 $\mu\textrm{g}$/mι to 100 $\mu\textrm{g}$/mι. Effects of low molecular weight EGF (LEGF) and high molecular weight EGF (HEGF) on the proliferation of keratinocyte in culture were also studied. The number of keratinocyte in culture was significantly increased with LEGF and HEGF respectively at the concentration of 10 ng/mι. Simultaneous treatment of the keratinocyte with LEGF, HEGF and TECA led to the increased proliferation of keratinocytes resulting 96% of the effect of a positive control, EGF isolated from mouse submaxillary glands.

Septoria centellae associated with leaf spot of Centella asiatica is reported for the first time in Korea. The fungus is described and illustrated in detail. It is also compared with related species of Septoria present on Centella and Hydrocotyle spp. with taxonomic comments. Two monoconidial isolates from Jeju and Wando were successfully cultured and have been deposited in the Korean Agricultural Culture Collection.

Centella asiatica (Linn.) Urban (Umbelliferae) which is also known as 'pegaga' is highly consumed and eaten raw as 'ulam' in Malaysia. C. asiatica is used in traditional medicines to treat various health conditions such as rheumatism, inflammation, syphilis, skin diseases and diarrhoea. Various reports exhibited that the crude extracts and isolated bioactive compounds of C. asiatica possessed a broad range of pharmacological activities such as anti-oxidant, anti-diabetic, anti-tumor, wound healing, anti-microbial, anti-inflammatory, immunomodulatory, hepatoprotective and memory enhancing properties. The pharmacological validation on anti-microbial and immunomodulatory of C. asiatica is very limited and several existence review papers related for this plant had not been focused for both activities. This review therefore attempts to combine the existing literature to offer immense scope for researchers engaged in validation of the traditional claims and bioactivities of this plant related with anti-microbial and immunomodulatory potential.

병풀(Centella asiatica) 추출물인 asiaticoside와 madecassoside는 항균성 및 피부재생 등의 효과로 인해 아시아 지역에서 치료용 연고에 사용되고 있으며, 병풀의 재배 및 추출효율을 높이기 위한 연구가 상업화를 위해 활발히 진행되고 있다. 본 연구에서는 환경 친화적인 추출 용매인 deep eutectic solvents(DESs)가 병풀에서 asiaticoside와 madecassoside의 추출 효율에 미치는 영향을 관찰하기 위하여 다양한 수소결합 받개(hydrogen bond acceptor, HBA)와 주개(hydrogen bond donor, HBD)의 혼합 몰비(HBA1: HBD2, HBA1:HBD3, HBA1:HBD4, 그리고 HBA1:HBD5)로 제조하여 추출용매로 사용하였며, 용매 추출에서 일반적으로 사용되고 있는 추출용매인 증류수(DW)와 methanol (MeOH)의 추출 결과를 최적화된 HPLC조건으로 분리하여 정량 분석하였다. 그 결과, DW와 DES를 3:7로 혼합하여 사용한 경우가 단일 MeOH를 사용한 경우보다 약 1.4배 높은 추출 효율을 보였다. 반대로 MeOH과 DES를 3:7로 혼합하여 사용하는 경우에서는 단일 MeOH를 사용하는 경우보다 약 6 % 낮은 추출 효율을 보였다.

To improve the shelf-life of Centella asiatica, Centella asiatica was treated with gel packs containing slow-released chlorine dioxide (ClO₂) gas at 3-5 ppm for 20 days at 4℃. The weight loss rate, as well as the changes in pH, color, and texture of the treated samples, were investigated. The weight of the control and ClO₂ gas-treated samples was decreased during the storage period. The change in weight of the control was slightly faster than that of the samples treated with 3 and 4 ppm ClO₂ gas. The pH of the control and the ClO₂ gas treated samples were decreased during the storage period and there was no significant difference between the control and ClO₂ gas treated samples. Concerning color (lightness, redness, and yellowness) changes of Centella asiatica during the storage period, there was no significant difference between the control and ClO₂ gas treated samples. The change in shear force in the leaf and stem of Centella asiatica during the storage period was slightly lower in the 4 ppm ClO₂ gas treated samples (in the leaf) compared to the control and 3 and 4 ppm ClO₂ gas treated samples (in the stem) compared to the control and 5 ppm ClO₂ gas treated sample.

A cDNA encoding farnesyl diphosphate synthase (FPS; EC2.5.1.1/EC2.5.1.10) was isolated from Centella asiacita (L.) Urban, using degenerate primers based on two highly conserved domains. A full-length cDNA clone was subsequently isolated by rapid amplification of cDNA ends (RACE) PCR. The sequence of the CaFPS (C. asiatica farnesyl diphosphate synthase) cDNA contains an open reading frame of 1029 nucleotides encoding 343 amino acids with a molecular mass of 39.6 kDa. The deduced CaFPS amino acid sequence exhibits 84, 79, and 72%, identity to the FPSs of Artemisia annua, Arabidopsis thaliana, and Oryza sativa, respectively. Southern blot analysis suggested that the C. asiatica genome contains only one FPS gene. An artificially expressed soluble form of the CaFPS was identified by SDS-PAGE. It had high specific activity and produced farnesyl diphosphate as the major isoprenoid.
