Background: Clausena harmandiana (Song Fa) leaves are a source of essential oil, in which the dominant compound is trans-anethole and reported the high antioxidant activity but the inhibition of biological enzymes related to anti-wrinkle activity is limit. Objectives: The objectives of this study are to investigate the ability of Song Fa leaf essential oil (SFEO) to inhibit enzymes that cause skin wrinkles and then to develop a bioactive ingredient in a nano-drug delivery system for anti-ageing cosmetic products. Methods: Fresh leaves of Song Fa were distilled and their essential oil obtained. Then, the anti-collagenase, elastase, and hyaluronidase activities were investigated and compared with those of an oleanolic acid standard. Then, SFEO was developed into a microemulsion by using Tween 80 as a surfactant and ethanol as a co-surfactant in a ratio of 1:1. Results: SFEO presented the highest inhibitory activities against hyaluronidase and collagenase (IC50 10.94{\textpm}1.06 and 19.06{\textpm}0.06 μg/ml, respectively), which were close to those of oleanolic acid (IC50 7.43{\textpm}0.58 and 16.75{\textpm}0.14 μg/ml), followed by elastase (IC50 121.47{\textpm}2.80 μg/ml). Two microemulsion formulas with different amounts of essential oil, 1\% and 5\% w/w, were formulated and evaluated for their enzyme inhibitory activities. The results showed that 5\% Song Fa microemulsion inhibited collagenase and elastase (35.78\% and 99.35\%, respectively) by more than 1\% Song Fa microemulsion (34.22\% and 92.67\%, respectively) and only the 5\% Song Fa microemulsion formula exhibited anti-hyaluronidase activity. Conclusion: This information will benefit the development of essential-oil-based products and increase the utilization of medicinal plants in the cosmetic industry.

Introduction: The presence of elastase and ROS can cause skin aging, phenolic compounds and flavonoids can be used to inhibit elastase activity and as an antioxidant. Objective: This research aimed to evaluate the anti-elastase, antioxidant activities, TPC and TFC of extracts from Myrica javanica. Methods: In this study, the leaves, stems and fruit of Myrica javanica were macerated with 96\% ethanol. The extracts obtained were analysed for anti-elastase and antioxidant activities. It was also evaluated for TPC and TFC. Result: IC50 anti-elastase on leaves extract (LE), stems extract (SE), and fruits extract (FE) respectively showed 64.71 ppm, 197.49 ppm, and no activity. The anti-elastase result of three extracts are lower if compared with Myricetine (9.54 ppm). SE showed highest DPPH and TPC value (IC50=16.36 μg/mL; 307.00 mgGAE/g dry weight) and LE showed highest FRAP and TFC value (421.68 Mol/gram; 15.80 mgQE/g dry weight). Conclusion: In summary, anti-elastase and antioxidant activity are influenced by differences in the content of compounds in the extract.

Introduction: Some Rubus were reported had anti-skin aging activity. Rubus fraxinifolius was one of Rubus genus which lives in Indonesian highland. Objective: This study was to examine elastase, tyrosinase, and oxidant inhibitory activity of R. fraxinifolius stem (RFS) extract. Methods: Extraction was done by a Soxhlet apparatus using methanol as solvent. Elastase inhibition activity was determined, which based on the formation of p-nitroaniline. Tyrosinase inhibition activity evaluated based on inhibition of mushroom tyrosinase by the sample with L-DOPA as substrate. The activity of antioxidant was determined using the DPPH radical scavenger method. LC-MS was used for prediction of naturally occurring phytochemicals. Results: The RFS extract yield was 9.03 \%. The RFS extract revealed inhibition activity against elastase and tyrosinase with IC50 128.85 ppm, and 155.19 ppm, respectively. DPPH radical scavenging activity gave IC50 63.04 ppm. Total phenolic content of the extract was 387.99+3.21 mg GAE/g extract. The LC-MS analysis showed the presence of at least 13 different organic compounds in RFS extract, which might contribute to the bioactivity. Conclusion: Therefore, this experiment further proved that RFS extract might be useful as a natural product ingredient of anti-photoaging skincare products because of its ability to inhibit elastase, tyrosinase, and as an antioxidant.

Objective: Leaves of M. malabathricum has been detected to contain quercetin and other phenolic contents. Quercetin has been proven to have elastase inhibitory activity. The aim of this study was to evaluate the effects of extraction method on total phenolic and quercetin contents as well as elastase inhibitory activity of M. malabathricum leaves extracts. Methods: Leaves powder was extracted by two conventional methods, maceration and reflux. Two different concentrations of ethanol were used as a solvent, 70 and 96\% ethanol. Leaves were also defatted with chloroform before further extraction. The total phenolic content was determined by the Folin-Ciocalteu method and quercetin content was determined by using the high-performance liquid chromatography method. Elastase inhibitor activity of leaves extract was determined on human neutrophil elastase in vitro. Results: Generally, 96\% ethanol obtained higher total phenolic and quercetin content than 70\% ethanol. However, defatted extract of 70\% ethanol contained higher total phenolic content than defatted 96\% ethanol. The highest elastase inhibitory activity of the sample was obtained from 70\% ethanol extract with the value of 89.50\% at 200 ppm, which is no significant difference compared to quercetin with the value of 93.86\%. Conclusion: Extraction methods and different concentration of solvents affect the total phenolic and quercetin contents of the extracts. M. malabathricum leaves have potential effect as anti-elastase as well as quercetin, where the anti-elastase activity of M. malabathricum leaves is not only due to quercetin.
