Research conducted to meet the needs of standard compounds in practical and research activities. The use of standard compounds improves the quality of a study. Piperine is the main secondary metabolite compound of the alkaloid group contained in Black PepperÃÂ Piper nigrumÃÂ L. The isolation method used is reflux and recrystallization methods. The reflux process in absorbing piperine compounds with diethyl ether solvent will help break down the cell walls to absorb the compounds optimally. Recrystallization was repeated 7-8 times until the crystals were pale yellow. The purity test used the TLC test with a solvent ratio of n-hexane and chloroform 6:4 with an Rf value of 0.04 cm. GCMS confirmation of 85% purity, UV-Visible spectroscopic test maximum wavelength 343 with absorbance 0.865 and FTIR test confirmed wave number 928 cm-1 (CO), 996 cm-1 ((CH bending of trans Ã¢â¬âCH=CH-), 1028 cm-1(=COC sym. st.), 1250 cm-1 (=COC asym. st.), 1440 cm-1 (methylenedioxy CH2bending), 1581 cm-1 (arom. C=C st.), 1631 cm-1 (-CO-N-). Based on the confirmed test results, the isolated compound is piperine from the alkaloid group. Piperine compounds can be used as standard compound preparations for testing the purity of compounds in research and chemistry lab work on natural ingredients.

Citrus fruit is widely grown in Indonesia. The skin of the fruit contains essential oils which can be used as aromatic ingredients in the perfume, pharmaceutical and culinary industries. Orange peel oil, extracted from different species, has different organoleptic qualities, specific gravity, refractive index value, acid number, ester number and solubility in 96% ethanol. This research aims to determine the differences in the essential oil components of sweet orange, lime and lemon peels and to determine the composition of commercial orange peel oil products. The method used to determine the differences in orange peel oil components is ATR-FTIR spectroscopy combined with two chemometric methods, PLS and PCA, to prove the differences quantitatively and qualitatively. The results of the PLS combination FTIR analysis showed that the most optimal wave number was shown in the 1450–1650 cm-1 area with an RMSEC value of 0.00553, then continued with PCA which showed the separation between samples. Results confirmed that the chemometric model effectively differentiated between essential oils from sweet orange, lime and lemon peels and those available on the market.
