Abstract

The bajakah (Spatholobus littoralis Hassk.) is one of the typical plants from Kalimantan Island, which has potential as a drug, one of which using as an antioxidant is due to the secondary metabolites contained therein. The aims of the research are to estimate the total phenolic content, total flavonoid content, and antioxidant capacity of the bajakah by different methods. Extraction was carried out by reflux method using a solvent gradient of n-hexane, ethyl acetate, and ethanol 96%. Phenols and flavonoid content were calculated using spectroscopy. Antioxidant capacity was measured against ascorbic acid and Trolox using the CUPRAC, DPPH, and FRAP methods and reported as mg Trolox equivalent (TEAC) and ascorbic acid equivalent (AEAC) per gram extract. The ethanol extract showed the highest antioxidant capacity for the CUPRAC and FRAP methods, the n-hexane extract for the DPPH method on both varieties of bajakah tampala. Each method provides significantly different antioxidant capacity values. The CUPRAC and FRAP methods found the highest antioxidant capacity in the white variety of bajakah ethanol extract. Meanwhile, in the DPPH method, saw the highest antioxidant capacity in the red variety of n-hexane bajakah extract. DPPH and CUPRAC give a positive correlation with TPC, where CUPRAC assay produced higher values than FRAP and DPPH assays.

Abstract

Introduction: Xenograft models play a pivotal role in preclinical studies for assessing the efficacy of anticancer medications. In this comprehensive review, we present an overview of current advancements and future prospects in xenograft research, focusing on their significance in guiding drug development and clinical translation. Aim: Our aim is to conduct an in-depth review of xenograft models, their utility in evaluating anticancer drug effectiveness and ultimately improve patient outcomes. Methods We conducted an in-depth literature search using databases such as ScienceDirect, Google Scholar and PubMed with keywords including "xenograft model, cancer CDX PDX." We then reviewed and analyzed relevant studies that utilized xenograft models in order to highlight key findings and contributions made through such models. Results: Our analysis showcases the essential role of xenograft models in assessing the efficacy of anticancer drugs. We discuss the benefits and limitations of these models, emphasizing their importance in guiding drug development and clinical decision-making. Conclusion: Xenograft models remain invaluable tools in preclinical cancer research despite their inherent limitations, with researchers continually striving to refine and enhance these models to ensure their reliability in an ever-evolving field of cancer therapeutics. Utilizing xenograft models allows researchers to evaluate anticancer drug activity more accurately while striving for improved patient outcomes.

Abstract

Pendahuluan: Rosella merupakan salah satu tanaman obat tradisional yang memiliki berbagai khasiat diantaranya meredakan batuk, sebagai antidiabetes, antikolesterol, antibakteri, dan meningkatkan sistem imun. Bahan aktif yang terdapat pada bunga rosella adalah grossypeptin, antosianin, gluside hibiscin dan flavonoid. senyawa tersebut diketahui dapat menurunkan kadar kolesterol. Tujuan: Penelitian ini bertujuan untuk mengetahui potensi penurunan kadar kolesterol dengan menggunakan ekstrak Bunga Rosella yang dibuat dalam bentuk biskuit. Metode: Penelitian ini menggunakan mencit yang dibagi kedalam empat kelompok. Kadar kolesterol ditingkatkan dengan induksi kuning telur. Bunga rosela dibuat dalam bentuk biskuit kemudian diberikan pada mencit secara peroral. Hasil: Setelah pemberian selama tujuh hari, kadar kolesterol masing-masing mencit menunjukkan penurunan yang signifikan. Kesimpulan: Biskuit ekstrak bunga rosella dapat menurunkan kadar kolesterol pada mencit. Kata kunci: Bunga rosella, biskuit, antikolesterol
