This study investigated the color change, enhancement of dye uptake, washing fastness, and light fastness of cotton and silk when dyed with Juniperus chinensis and Terminalia chebula (combination dyeing) using various methods. The dyeing methods were 1) dyeing Juniperus chinensis extract and Terminalia chebula Retzius extract sequentially (J-T), 2) dyeing Terminalia chebula Retzius extract and Juniperus chinensis extract sequentially (T-J), 3) dyeing Juniperus chinensis extract and Terminalia chebula Retzius extract simultaneously (J+T), and 4) dyeing Juniperus chinensis extract 4 times repeatedly and followed by a dyeing Terminalia chebula Retzius extract in sequence. In terms of increased dyeing uptake, combination dyeing (dyeing 2 times like method 1, 2, 3) had the same impact as the repeated dyeing (method 4). The color of J, T combination dyeing showed wide range of mixed YR series, Y series resulting from Terminalia chebula Retzius, and R series resulting from Juniperus chinensis. In cotton, J-T dyeing method showed superior enhancement of dye uptake, and T-J method in silk. In both of the cases, Y series color from Terminalia chebula Retzius extract was mainly shown (Y series color was superior to R series color after dyeing). Therefore, it is recommended for cotton to implement T-J method and for silk to implement J-T method in order to enhance both dyeing uptake and emphasize the color of R series. The K/S value of combination dyed fabrics was decreased by increasing washing time; however, the K/S value of combination dyed fabrics was increased by increasing UV irradiation time. But after repeated washing and longer UV irradiation, ${\Delta}E$ value of combination dyed fabric became smaller compared to fabric dyed with Juniperus chinensis only. Thus, it was found that after J, T combination dyeing, fabric became less prone to fading by washing and UV than after Juniperus chinensis single dyeing was done.

Cancer is an abnormal growth of cells in body which leads to death. These cells are born due to imbalance in cell proliferation mechanism. In 2018, WHO released new statistics on cancer incidence, mortality, and prevalence worldwide i.e., GLOBOCAN 2018 estimates for 28 types of cancer in which more prevalence of cervix and breast cancer. According to survey, in India about 7.8 million cancer deaths and 11.5 million new cases arise in 2018, which will increase to 19.3 million new cases per year by 2025. Though breast cancer as such is not explained anywhere in Ayurvedic compendia, correlations can be done with the Stana Arbuda. Ayurveda, the ancient system of medicine came into existence 1000's of years ago with an objective of maintaining the health of people and treating diseases. Many herbs used in Ayurveda have been screened for activity against cancer and in-vitro and in-vivo studies have given promising leads. The plant, called as "Mother of Medicine", Haritaki has been extensively studied for its various ailments because of its extraordinary healing potency. Haritaki (Terminalia chebula Retz.), Family: Combretaceae have a great therapeutic value and is widely distributed in India. Dried fruit of Terminalia chebula contains high quantities phenolic compounds consist of ellagic acid, gallic acid and chebulic acid. The fruit extract of T. chebula is having different biological properties like anticancer, antioxidant, hepatic and renal protective activities etc. In this study, we focus on the use of CO₂ extract of Terminalia chebula, on the breast cancer cell line MDA-MB-231. All tests proved that CO₂ extract of Terminalia chebula containing active chemical component, therefore our experiment showed the positive results for CO₂ extract of Terminalia chebula against breast cancer cell line cancer MDA-MB-231. The MTT assay results were used to evaluate the anti-cancer activity of the extract. The percentage of cell growth and cell viability were calculated from tabulated result values of MTT assay. Cell viability MTT assay also showed significant growth inhibition, at the same time statistical analysis of MTT assay also proved significant results.

This study was undertaken to test for antiviral activity of the aqueous extracts prepared from 4 medicinal plants of Korea (Terminalia chebula, Sanguisorba officinalia, Rubus coreanus, Rheum palmatum). Aqueous extracts were assayed for the inhibition of hepatitis B virus (HBV) replication by measurement of HBV DNA and surface antigen (HBsAg) levels in the extracellular medium of HepG2 2.2.15 cells. All extracts decreased the levels of extracellular HBV virion DNA at concentrations ranging from 64 to $128{\;}\mu\textrm{g}/ml$ and inhibited the production of HBsAg dose-dependently. Among the 4 tested plants, Terminalia chebula exhibits the most prominent anti-HBV activities. Our findings suggest that these 4 medicinal plants may have potential to develop as specific anti-HBV drugs in the future.

The present communication attempts to evaluate the physicochemical and preliminary phytochemical studies on the fruit of Terminalia chebula Retz. Combretaceae family. Haritaki is one of the most celebrated herbs in the Indian traditional medicine system, Ayurveda. Terminalia chebula is known to exhibit different properties like anticancer, anti-inflammatory, anti-protozoal, antimicrobial, antioxidant, hepato and renal protective activities, and in the management of metabolic syndrome. As there is no detailed standardisation work reported on fruit, the physicochemical parameters, preliminary phytochemical constants, heavy metals, analysis are carried out. The phytochemical screening indicated the presence Tannin, Alkaloid, Phenol, Carbohydrate, Steroids, Protein and Resin compounds in CO₂ extract of Haritaki. The present investigation will helpful in assessing the quality and purity of a crude drug. Thus, the study provides facts that CO₂ extract of Haritaki contains medicinally important bioactive phytochemical compounds which justifies the use of plant species as conventional medicine for treatment of many diseases.

본 연구에서는 Terminalia chebula Retz.의 성숙열매인 가자 메탄올 추출물(TCME)을 이용하여 HAT 활성을 억제함으로써 AR의 아세틸화 감소를 유도하여 전립선암세포의 성장을 억제하였다. TCME의 처리는 HAT 활성을 100 ${\mu}g/mL$의 농도에서 50% 이상 저해하였으며, p300과 CBP 등의 특이적 HAT 단백질에서도 유의적인 저해활성을 보였다. TCME를 0~100 ${\mu}g/mL$로 안드로젠 수용체 의존적 전립선 암세포인 LNCaP에 처리한 결과, reporter assay에서 AR 매개 전사를 억제하고 AR target gene의 mRNA 발현을 억제하였다. 동일 농도에서 AR의 아세틸화가 감소한 결과를 보였으며, 결국 전립선암세포주의 성장억제를 유도하였다. 이같은 결과에서 가자 메탄올 추출물은 HAT 활성을 억제하며, AR의 아세틸화를 감소시킴으로써 효과적인 전립선암 치료소재로 개발될 수 있는 가능성이 있음을 제안한다.

We investigated the effect of aqueous extract of Terminalia chebula (Combretaceae)(TCAE) on the immediate hypersensitivity reaction in vivo and in vivo. TCAE (0.01 to 1 g/kg) dose-dependently inhibited compound 48/80 induced systemic anaphylaxis in mice. When TCAE was pretreated at concentrations ranging from 0.01 to 1 g/kg, the plasma histamine levels were reduced in a dose-dependent manner. TCAE (0.1 and 1 g/kg) significantly inhibited local immunoglobulin E (IgE)-mediated passive cutaneous anaphylactic reaction. TCAE (0.001 to 1 mg/ml) also dose-dependently inhibited the histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80 or anti-dinitrophenyl (DNP) IgE. TCAE (0.01 to 1 mg/ml) had a significant inhibitory effect on anti-DNP IgE-induced tumor necrosis $factor-{\alpha}$ production from RPMC. These results indicate that TCAE inhibits immediate hypersensitivity reaction in vivo and in vitro.
