Rapid analysis of alpha-glucosidase inhibitory activity of Psychotria Malayana jack leaf applying infrared fingerprinting
Psychotria malayana Jack is the plant belongs to Rubiaceae family and known in Malaysia as “meroyan sakat/salung”. Despite its potential use as an antidiabetic agent, a rapid analytical approach for the quality control of this plant has not been developed. Thus, the objective of this study was to es...

Psychotria malayana Jack is the plant belongs to Rubiaceae family and known in Malaysia as “meroyan sakat/salung”.
