Abstract

Kaffir lime peel extract (Citrus hystrix DC.) contains flavonoids and alkaloids still rarely used as medicine; however, its toxicity is lack of the research until now. The research aimed to determine the effects of toxicity in the extracts by Brine Shrimp Lethality test (BSLT). The extraction used maceration and infusion. The former used ethanol of 70% with the thick extract of 3.81 mg and the letter used aquadest with the dried extract of 2.77 mg. The screening-was conducted by observing the color change in the extract and obtained the toxicity effects at the concentration of 1 ppm, 3 ppm, 5 ppm, 7 ppm, and 9 ppm by obtaining LC50 values for both the ethanol extract of 0.98 ppm and water extract of 1.20 ppm. The results showed that the water and ethanol extracts of kaffir lime peel had toxic properties.

Abstract

Bagore plant (Caesalpinia crista L.) belongs to the tribe Leguminosae and grows wild on the coast. Standardization is important to guarantee potency uniformity benefits by ensuring the concentration of active ingredients through qualitative analysis of secondary metabolites, ensuring the safety and stability aspects of extracts and increasing the economic value of extracts by various analyses such as specific and non-specific parameters. This study aims to standardization bagore seed extract (Caesalpinia crista L.) and determine the value of specific and non-specific parameters of. Samples were obtained from Binuang District, Polewali Mandar Regency, West Sulawesi Province, macerated with 96% ethanol then standardized with specific and non-specific parameters. The results of the study obtained specific parameter values as follows; organoleptic tests obtained extracts in the form of viscous, light brown in color, characteristic smell and very bitter taste; The content of soluble compounds in water is 14.361%; the content of soluble compounds in ethanol is 15.708%; positively contains flavanoid compounds, alkaloids and saponins; and the value of non-specific parameters as follows: drying shrinkage which is 0.439%; specific weight of 0.859 grams; moisture content of 2.589%; total ash content of 4.216%, insoluble ash content of acid which is 0.630%; The mold number is < 1.0 x 101 colonies/ml and the yeast is < 1.0 101 colonies/ml; lead metal contamination (Pb) is 0.003 g / g and cadmium (Cd) is 0.01 g / g. Research shows bagore seed extract (Caesalpinia crista L.) provides results according to the general standard parameters of medicinal plant extracts.

Abstract

Indonesia's biodiversity that exists around its community environment has been used for generations as a food and medicinal ingredient, one of which is temulawak (Curcuma xanthorriza.). Temulawak is used as a raw material for herbal aches and pains because it is efficacious to help reduce or eliminate inflammatory diseases in the body such as arthritis. The purpose of this study was to identify the presence of curcuma content in several aching and rheumatic herbs using an experimental design. The method used was a qualitative test using thin layer chromatography (TLC) with n-hexane -acetone as the mobile phase (6:4). The results of TLC observations at 254 nm and 366 nm UV lamps showed yellow spots on the comparator temulawak simplicia and the Rf value of the curcuma simplicia was 0.690. The results of the identification of the five samples of herbal medicine stiff and sore by TLC proved to contain temulawak simplicia.
