Introduction: Idat (Cratoxylum glaucum Korth.), belonging to the genus Cratoxylum, is known to contain xanthone, quinone, flavonoids, and other phenolic compounds. Objectives: to analyze total phenolic, flavonoid, antioxidant activity, and inhibitory xanthine oxidase activities of leaves, stem, and cortex of idat. Methods: Extraction of leaves, stem, and cortex of idat was carried out by reflux using n-hexane, ethyl acetate, and ethanol as a solvent. Antioxidant activity was tested by the DPPH method and calculated to get the antioxidant activity index (AAI). Determination of total phenolic and flavonoid levels by ultraviolet-visible spectrophotometry. Results: Spectrophotometers measured the inhibitory activity on xanthine oxidase in 96-well plates with allopurinol as standard. Total phenolic and flavonoid content from C. glaucum extracts varied from 6.62 to 48.77 g GAE/g extract and 1.54 - 25.96 g QE/100 g extract, respectively. The ethanol extracts of leaves, stem, and cortex were very strong antioxidant activity with Antioxidant Activity Index (AAI) values 3.89; 4.55; 10.50, meanwhile AAI of ascorbic acid and quercetin 9.46 and 14.81 respectively. The n-hexane of stem extract had a strong xanthine oxidase inhibitory activity with the IC50 was 36.64 μg/ml, while allopurinol was 5.02 μg/ml. Conclusions: Total phenolic content contributed to antioxidant activity. Phenolic compounds in leaves extracts led to the xanthine oxidase inhibitory and antioxidant activities. The extract of C. glaucum was active as an antioxidant and potentially an inhibitor of xanthine oxidase agents.

Introduction: Boehmeria is a genus that has the potential to be natural medicine and also has benefit in industry. This genus consists of 82 plants that includes numerous species, subspecies, and varieties. The objective of this review is to provide an overview of chemical and pharmacological characteristics of Boehmeria genus based on research studies. Methods: The reference articles have DOI and were obtained through database from such as Science Direct and PubMed website to ensure their validity and reliable contents. This literature study was made by using minimum 50 literatures from the last 10 years. Results: There are 16 species of Boehmeria genus confirmed to have chemical compounds, and 9 species of which reported to exhibit pharmacological activity in the form of extracts and single compound isolates. Conclusion: Based on this study, it was known that some Boehmeria species contained abundance of Boehmeriasin A, boehmeriasin B, chlorogenic acid, epicatechin, (Z)-9,10,11-trihydroxy-12 octadecenoic acid, catechin, β-sitosterol, rutin, luteolin-7-glucoside, naringin and hesperidin. Boehmeria genus had various activities such as anticancer, anti-inflammatory, antidiabetic, antihyperlipidemic, antimicrobial, antioxidant, and anti-hepatitis B.
