Markherb Standardized Extracts are quantified reference extracts from Indonesian medicinal plants to be used as references for authentication botanicals, herbal drugs, and other plant-based products. The extracts are aqueous ethanolic extracts of the authenticated plant from our collection gardens to guarantee the botanical identities. The standardized extracts are delivered as dry powder in amber vials containing 1 g of samples. The quality of each extract is confirmed with a Certificate of Analysis (CoA) showing the identity and quantity of the compounds occurred in the extract, and a Technical Information showing the extract preparation method, detection and quantification methods, and recommendation use.
