Ceylon olive (Elaeocarpus serratus L.) leaves have shown many pharmacological effects. Standardization of crude drug and extract needs to be conducted to assure the quality of the said material and further to support the pharmacological, pharmacokinetics, and toxicity effects. Standardization of Ceylon olive leaf extract is carried out to determine the standard parameters of crude drug and ethanolic extract of Ceylon olive leaves. Determination of the quality standard of crude drug and extract includes specific and non-specific parameters. The extract was obtained from a 70% ethanol maceration method with a yield of 16.02%. Macroscopic observations showed crude drugs of Ceylon olive leaves occurred as green in color, lanceolate leaves, 2-12 mm stems, and jagged leaves not deep, black spots, 10-15 side leaf bones, 6-18 cm long and 2-6 cm wide. Organoleptic of ethanolic extract of Ceylon olive showed thick consistency, blackish-brown colored, with a distinctive odor and a bitter taste. The water-soluble extractive value in crude drugs and extract was 16.48 and 51.54%, while the ethanol-soluble extractive value was 23.17 and 53.67%, respectively. The extract contained tannins, flavonoids, terpenoids, and saponins. Moisture content in the crude drugs and extracts was 22.09 and 25.53%. Total ash content in crude drugs and extracts was 33.53 and 30.62%, while their acid-insoluble ash content was 15.94 and 10.06%, respectively. Loss on drying of the crude drugs and extracts was 20.52 and 23.84% respectively. As the standard parameters of crude drugs and ethanolic extract of Ceylon olive leaves are not yet included in any formal monograph in Indonesia, the values of parameters reported in this study should be used as the reference of the standard quality parameter for those materials.

Ganitri (Elaeocarpus ganitrus Roxb) is a plant known for its antibacterial properties, particularly in its leaves. The leaves of Ganitri contain antibacterial compounds such as flavonoids, alkaloids, and tannins. The objective of this study is to investigate the antibacterial activity and determine the minimum concentration of ethanol, methanol, and distilled water extracts from Ganitri leaves in inhibiting the growth of Escherichia coli and Shigella flexneri bacteria. A preliminary study of phytochemical with Thin Layer Chromatogram (TLC) and antibacterial study was conducted. The study was conducted in vitro by disc diffusion method with positive control of ciprofloxacin 50 µg/mL and negative control of sterile aquadest. The extract concentration series used were 10, 20, 30, 40, 50, and 100%. The extracts of ganitri leaves have antibacterial activities against Escherichia coli and Shigella flexneri bacteria. The TLC results were observed under visible light at 254 and 365 nm. Ethanol, methanol, and aquadest extracts of ganitri leaves produce spots that are almost comparable to the compounds of quercetin and tannic acid. The inhibitory zone range of the extracts in Escherichia coli bacteria is 10.33-19.66 mm with a strong category. In comparison, the inhibitory zone range of Shigella flexneri is 8.88-22.62 mm with a moderate-very strong category. ANOVA test results stated a significance value of p = 0.001 (p <0.05). Therefore, it can be concluded that the ethanol, methanol, and aquadest extracts of ganitri leaves had significant differences. The minimum concentration of each extract in inhibiting the bacteria Escherichia coli and Shigella flexneri is 10%.

Ganitri (Elaeocarpus ganitrus Roxb.) is one of the traditional medicinal plants that grows in Kebumen Regency, every part of the plant can cure various diseases. The leaves are known to contain carbohydrates, alkaloids, flavonoids, saponins, steroids, glycosides and anthraquinones which show antibacterial activity. Research on the development of pharmaceutical preparations from ganitri leaves has never been done. Seeing the large number of ganitri plants that grow and their great potential, this study aims to develop a pharmaceutical formulation in the form of a Hand Sanitizer.The results showed that formula 1 in the hand sanitizer spray preparation with a concentration of 1% ganitri (Elaeocarpus ganitrus Roxb.) leaf ethanol extract and 5% aloe vera had the best physical evaluation of the preparation. The data from the physical evaluation were analyzed statistically, namely the pH test and the viscosity test. The results of the normality test data and homogeneity test data with P> 0.05, which means that the data is normally distributed and homogeneous. The results of the ANOVA test showed that in the pH test there was no significant difference because the significance value was p> 0.05, while in the viscosity test the significance value was P < 0.05, it could be concluded that the average concentration of each formula in the viscosity test had a significant difference and systemically proven. Formulas 1, 2 and 3 had the diameter of inhibition against all test bacteria with the best inhibition in formula 2 of 18 mm on e.coli bacteria, 17.19 mm on s. aureus bacteria and 17 mm on shigella bacteria.
