Abstract

Isolation and identification of Pinostrobin compounds in Temu Kunci Rhizomes (Kaempferia pandurata Roxb) were conducted in this study. The isolation and identification methods used were extraction, crystallization & recrystallization, Thin Layer Chromatography, and (4) Infrared (IR) Testing. The extraction results were followed by crystallization and recrystallization processes. The recrystallization produced a yellow solid isolate. A Thin Layer Chromatography test was carried out to determine the purity of the isolate using the eluent Chloroform : n-hexane of 6:4, Chloroform : Ethylacetate of 7:3. A comparison of the Retention Factor (Rf), and the Rf value of the phinostrobin standard indicates that the positive test sample contained the Pinostrobin compound. The Infrared spectrum indicates that the sample belongs to the flavonol group. It is confirmed from the functional groups of the isolates that are compatible or identical to the functional groups in the pinostrobin compound.

Abstract

Flowers besides being used as ornamental plants, they can also be consumed. Flowers that can be consumed are called Edible Flowers. Edible flowers in general can be consumed directly, usually in tea or can be served in the form of processed food. Edible flowers contain phytochemical compounds such as anthocyanins, flavonoids, phenolics, carotenoids which are useful as antioxidants. Indonesia is rich in biodiversity with a variety of plant species that can grow, including edible flowers. There is diversity, but only a few edibles that can grow and are familiar to Indonesian people will be reviewed in this article.

Abstract

Bacterial infection is one of the leading causes of chronic diseases and ongoing risks of mortality that continuously threaten public health globally. Improper use of antibiotics can lead to pathogenic bacteria developing resistance to antibiotics and cause dangerous side effects. Therefore, searching for alternative antibiotic sources derived from natural materials is essential. One type of plant that has the potential as an antibacterial agent is Canavalia rosea. This research aims to qualitatively assess the phytochemical content using tube methods and evaluate the antibacterial activity of the ethyl acetate fraction of Canavalia rosea extract using the disc diffusion method. Canavalia rosea leaves were extracted using a maceration method using 96% ethanol, and fractionation was done using ethyl acetate. Phytochemical analysis showed alkaloid, saponin, flavonoid, polyphenol, and tannin compounds in the Canavalia rosea flower extract. The antibacterial activity of the ethyl acetate fraction of the extract showed a significant inhibition zone against the growth of Staphylococcus aureus bacteria. At a concentration of 9 mg/mL, the inhibition zone reached 20.31 ± 0.27 mm, falling into the moderate to strong category. While at a concentration of 1.5 mg/mL, the inhibition zone reached 5.13 ± 0.32 mm, indicating lower inhibitory effects. Statistical analysis showed that the ethyl acetate fraction of Canavalia rosea extract has significant antibacterial activity, with each concentration having different effects in inhibiting the growth of S. aureus.
