Gitingensine is a natural product found in Kibatalia laurifolia belonging to Apocynaceae which is a steroid having the activities such as anti-inflammatory, anti-spasmodic and anti-cancer activity. Cevadine is used as an internal standard for chromatographic analysis. The elution was performed on BEH C18 (2.1 × 50 mm, 1.7 µm) column at 30 °C with a mobile phase distribution Acetonitrile: 0.1% orthophosphoric acid (60: 40) respectively. The flow rate was well- kept at 0.3 mL min-1. Retention times for Gitingensine and Cevadine were found to be 2.005 and 1. 395 min, respectively. The regression equation was found to be linear in the range of 12.5 – 75 µg/mL with a high correlation coefficient (0.999). Recovery of Gitingensine was obtained as 100.04%. Validation was done as claimed by ICH guidelines with respect to accuracy, sensitivity, robustness, and precision studies. From the insignificant variations in the analysis by changing the mobile phase, temperature, and flow rate, the robustness was studied. All the validation parameters were found to be within the specifications. Forced degradation studies revealed that when the influence of acid, alkali, peroxide, thermal, photolytic, and hydrolytic conditions were applied on the drug, it was stable. Hence, it can be concluded that the developed RP-UPLC method is economical, precise, and robust and can be adopted in regular Quality control analysis.","PeriodicalId":14317,"journal":{"name":"International Journal of Pharmaceutical Chemistry","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75639119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ABP is one tool in a kit of intelligent anti-doping practices meant to deter and detect the use of prohibited substances in sport. In 2013, the WADA Athlete Biological Passport Guidelines introduced a second module, the Steroidal Module, which became operational since January 1, 2014. The Steroidal Module monitors an athlete’s steroidal variables over time that may be indicative of steroid abuse. This paper summarized the details of samples requested for confirmation on GC/C/IRMS in year 2015 & 2016 to understand the pattern of generation of Atypical Passport Finding Confirmation Procedure Request (ATPF-CPR). Interestingly, out of total 26 cases of ATPF-CPR received by NDTL, three samples with normal steroid profile showed exogenous origin of endogenous steroids on GC/C/IRMS analysis,\u0000which proves the effectiveness of Steroidal Module.

These microbes effects humans, animals and plants and produces diseases. As per the recent report of World Health Organization (WHO), the cases of Antimicrobial resistance (AMR) is continuously rising, which causes ineffective treatment and prevention of infections caused by bacteria, viruses, fungi and parasites. AMR occurs when these microbes gets resistance and the medications gets ineffective against these microbes, which makes treatment of common infections difficult and consequently increases the risk of severe illness, spread of disease and death. Because the medicines\u0000becomes purposeless, infections continue to exist in the body and increases the likeliness of spread to others. WHO recommends reduced use of synthetic antibiotics and raised use of herbal antimicrobial drugs. These are the ways by which the AMR can be controlled or abolished. Herbal drugs can be used for this purpose because these are considered to be effective with no or less side effects. In the present article we discussed about peptic ulcer, causative agent of peptic ulcer and the medicinal plants which can be used to treat this disease. Twenty medicinal plants were listed which contains both antibacterial and antiulcer activity.
