The present study analyze the differences in metabolite content in UKMR-2 calyces in response to different soil media formulation ratio treatment by applying multi-step infrared based fingerprinting. The cultivation using two different media ratio (top soil, organic matter and sand); SM1 with 2:1:1 v/v/v and SM2 with 2:1:2 v/v/v. Multi-step infrared based fingerprinting: one dimensional infrared (1D-IR), second derivative infrared (SD-IR) and two dimensional correlation infrared (2D-IR) spectroscopy were used. The 1D-IR spectrums revealed a similar absorption in the fingerprint zone (1900 - 650 cm-1). SD-IR spectrums clearly showed have more peaks with different shape, position and intensity in the fingerprint zone. 2D-IR synchronous correlation spectrum clearly distinguished the metabolite content in the UKMR-2 calyx extract in the range of 1000 – 650 cm-1 . Therefore, multi-step infrared based fingerprinting has the potential as one of the effective methods to discriminate extract samples with similar infrared fingerprint features.
