Do you have a protocol for total estimation of terpenoids and glycosides using UV spec methodology? I only have a protocol for their estimation using TLC.
Terpenes and terpenoids are primary constituents of essential oils of different type of plants and flowers. 1) T Salkowski Test is applied for estimation of terpinoids. For which plant extract is mixed with 2ml of chloroform and concentrate H2SO4 (3ml) is carefully added to form a layer. A reddish brown coloration of the interface is formed to show positive result of the presence of terprnoids.
