Caesalpinia pulcherrima (L.) Sw. is traditionally used in medicine and is thought to be influenced by the presence of secondary metabolites, especially phenolic compounds and flavonoids. However, identifying the phytochemical compounds of Caesalpinia pulcherrima (L.) Sw. plants, especially on the pods, are less discussed. Here, we propose research on the identification of secondary metabolite compounds of pod-purified extract from Caesalpinia pulcherrima (L.) Sw. using phytochemical screening and also the determination of total phenolic and total flavonoid content. The extraction of Caesalpinia pulcherrima (L.) Sw. pods were processed by maceration and fractionation methods to obtain the purified extract. Total phenolic contents were determined using the Folin-Ciocalteu method. Meanwhile, total flavonoid contents were determined using the AlCl3 method. The result showed that the purified extract of Caesalpinia pulcherrima (L.) Sw. pods contained phenolics, flavonoids, alkaloids, and saponins. The total phenolic and total flavonoid content in the pod purified extract were 326.038 mg GAE/g extract and 290.026 mg QE/g extract, respectively.

Isolation of flavonoid compounds from Salam (Syzygium polyantha Wight) leaves has been done by maceration technique with methanol solvent. Methanol extract obtained was evaporated and dissolved with ethyl acetate. The solution was then concentrated and evaporated. The ethyl acetate fraction was dissolved with methanol and partitioned with n-hexane solvent. The methanol layer was evaporated and then tested with Benedictâ€™s reagent and then acidified with HCl 6% while heated. It was then extracted partition with chloroform. The chloroform layer was separated using Column Chromatography with silica gel as the stationary phase and n-hexane: ethyl acetate 90:10, 80:20, 70:30, and 60:40 v/v, respectively as the mobile phase. The pure compound was paste, brownish red, mass = 8.5 mg, and Rf=0.60. It was a positive reaction with flavonoid compound reagents. The compound was further identified by using UV-Visible, FT-IR, and 1H-NMR spectroscopy. Spectroscopy data obtained indicated that the compound is a flavonoid.

This research is one of the diversification efforts of food substances to create economically valuable nutritious food. It has been researched the use of isolation of protein from the waste of the Ketchup Industry as the mixture of crackers with various comparisons between isolating of the waste of protein from Ketchup Industry and cassava by adding an extract of carrot about its nutrient content also. The analyzing nutrient is protein content by using the Kjeldahl method and turning to dust Î² â€“ carotene using the spectrophotometer and organoleptic test about the taste of crackers using a hedonic scale. The highest protein content and Î² â€“ carotene is found in the crackers in comparison (1:6:3) namely 5,38 % and 53,59 ppm. Moreover, the lowest protein content and Î² â€“ carotene is found in the crackers in comparison (1:0:0) namely 2.35 % and 27.49 ppm. The most delicious, crispy, and the most people like is the crackers with comparison (1:4:2).

Kalanchoe ceratophylla Haw. is a medicinal plant traditionally used to address various health disorders. Its biological activities are believed to be associated with its secondary metabolites, particularly phenolics and flavonoids. Despite its traditional use, scientific information This study assesses the phytochemical composition alongside the total phenolic and flavonoid contents in the stem and leaf preparations of Kalanchoe ceratophylla Haw. Phytochemical screening confirmed the presence of alkaloids, flavonoids, tannins, and phenols in the stem extract, while the leaf extract also contained steroids. The total phenolic content was 7.43 mg GAE/100 g extract for stem and 7.11 mg GAE/100 g extract for leaves, whereas total flavonoids amounted to 0.324 mg QE/g extract (stem) and 1.621 mg QE/g extract (leaves). These findings highlight the potential use of K. ceratophylla, especially its leaves, for developing antioxidant-based herbal medicines.
