“…According to research Suproborini et al (2020) and Dali et al (2017) the brewing results of Strobilanthes crispus L. leaves have anti diabetic and anti cancer benefits. According to the research results of Djamil et al (2020) stated that the thick extract of keji beling leaves has the ability to inhibit the activity of the αglucosidase enzyme, thus it has the potential to be developed for anti-diabetic herbal medicine as well.…”

Keji Beling (Strobilanthes crispus L.) is one of medicinal plants in Acanthaceae family. The leaves are the part that is often used as the herbal products such as; herbs, tea and the others. This study aims to determine the characteristics of the functional groups of organic compounds, mineral content and antioxidant activity in the leaf extract of Strobilanthes crispus L. using pottery. Test analysis in research using FTIR, SEM-EDX, XRF. The result of showed the presence of CH alkenes, CH aromatic, C-O alcohol/ether/carboxylic acid/ester, C-N amine, NO2 Nitro compounds, O-H hydrogen bond alcohol /phenol and N-H amines/amides The mineral composition contained macro elements of Ca, K, P and S. While the identified micro minerals are Si, Fe, Mo, Sr, Mn, Ba, Cu, Zn, and Ni. The microscopic morphology of Strobilanthes crispus L. leaf extract is in the form of porous solid particels, thus it is to have high water solubility. The results of the antioxidant test using the DPPH method obtained an IC50 value of 19.20 ppm which is included in the group of very active antioxidants

“…A compound is said to have very strong antioxidant activity if the value is (IC 50  50 ppm), strong (51  IC 50  100 ppm), moderate (101  IC 50  150 ppm), weak (151  IC 50  200 ppm), and very weak. (IC 50  201 ppm) (Molyneux, 2004); (Dali et al, 2017). Therefore, the antioxidant activity of the ethanol extract of Dengen leaves was strong (IC 50 = 77.3269 ppm) (Table 3) (Figure 1).…”

“…DPPH solution (blank) (1 mL), test solution (20, 40, 60, 80, 100 g/mL) (4 mL) + DPPH 0.3 mM (1 mL), and ascorbic acid solution (20, 40 , 60, 80, 100 g/mL) (4 mL) + DPPH 0.3 mM (1 mL) were incubated at 37 o C for 30 minutes. The absorbance of each solution was measured by UV-Vis spectrophotometer at a wavelength of 510-520 nm (Marliani et al, 2015;Dali et al, 2013;Dali et al, 2017;Souhoka et al, 2019;Yanti et al, 2021). The percentage of inhibition was calculated using Equation (1).…”

Research on the extraction of chemical components of Dengen (Dillenia serrata Thumb) leaves using the MAE (microwave-assisted extraction) method and activity as an antioxidant and toxicity test has been carried out. This study aimed to extract the chemical components of Dengen leaves using the MAE method and to test the antioxidant activity and toxicity of the ethanol extract of Dengen leaves. The chemical components of Dengen leaves were extracted by the MAE method and obtained ethanol extract with a yield of 47%. Dengen leaves ethanol extract was partitioned with n-hexane and ethanol as solvents and obtained yields of 5% (n-hexane) and 65% (ethanol). The chemical components of Dengen leave ethanol extract were identified by phytochemical screening. The results of phytochemical screening showed the presence of secondary metabolites of alkaloids, flavonoids, saponins, polyphenols, terpenoids, and steroids. The antioxidant activity test of the ethanol extract of Dengen leaves was carried out using the DPPH (2,2-diphenyl-1-picrihydrazil) method and obtained the value of IC50 = 100,363 ppm (strong antioxidant). A toxicity test of the ethanol extract of Dengen leaves was carried out using the BSLT (Brine Shrimp Lethality Test) method and obtained the value of LC50 = 18.3443 ppm (very toxic).

Isolation and identification one of chemical compound mono-terpene from Keji beling plant (local name) (Strobilanthes crispa) has been done. Extraction was carried out by maceration of the keji beling leaf powder with ethanol 96%, then partitioned with water-ethyl acetate. Ethylacetate extract was isolated and purified by a cytotoxic guide fractionation system with Brine Shrimp Lethality Test (BSLT) on column chromatography (SiO2; n-hexane - ethylacetate = 20 : 1); and preparative Thin Layer Chromatography (TLC) (SiO2; n-hexane - ethylaseate = 10 : 1) which gave one compound in oily form. Based on identification by infra red spectra and gas chromatography-mass spectra (GC-MS), the compound is a monoterpene D-limone which has a cytotoxic power of 73,11 ppm.
