“…According to research by Aminah et al [7], the total flavonoid content of the ethanolic extract of avocado peel is 4,0122 mg QE/gram extract. According to research by Vinha et al [34], avocado peel from Alvarian contains a total phenol content of 679.0 GAE mg/100-gram extract and a total flavonoid 44.3 QE mg/100gram extract. This study is in accordance with the theory that polyphenols increase the proliferation and production of collagen in fibroblasts.…”

The skin is a complex organ that protects the body from the external environment. The skin has a variety of functions such as providing a physical permeability barrier, protection from infectious agents, thermoregulation, sensation, protection against ultraviolet (UV) rays, regeneration, and wound healing. Clinically, aging skin is characterized by loss of hydration, rough texture, irregular pigmentation, yellowish discoloration, telangiectasia, deep wrinkles or wrinkles, thinning of the skin, and fine lines. One of the plants that can be used as natural ingredients that are rich in antioxidants and interesting to study is avocado (Persea americana Mill.) from the Lauraceae family, which is a plant that has medicinal properties and contains a variety of nutrients. Besides being consumed as food, avocados are also used as a mixture of cosmetic products. This study aims to assess the anti-aging effectiveness of avocado peel extract on increasing collagen levels, elasticity, and hydration in male rats. A total of 25 rats were divided into 5 groups, each group consisting of 5 white rats; control group (ointment base), avocado peel extract ointment group 2.5%, 5%, 7.5%, and 10%. The entire group of rats will be measured the condition before treatment with the Skin Analyzer EH 900 U including levels of collagen, elasticity, and hydration. After measuring the initial skin condition, the treatment was started by applying ointment until it was evenly distributed over the marked area, the ointment was applied according to the groups that have been set above, the application was carried out 2 times a day for 4 weeks. Changes in skin condition were measured weekly for 4 weeks using the EH 900 U skin analyzer. The results of this study indicate that the methanol extract of avocado peel contains phytochemicals in the form of alkaloids, tannins, phenols, flavonoids, and glycosides. Then the phenolic, flavonoid, and tannin content of the avocado peel methanol extract was 59.55 GAE mg/gram extract, 2.96 QE mg/gram extract, and 22.63 TAE mg/gram extract. After 4 weeks of treatment, there was a significant change in the level of hydration, collagen, and skin elasticity (p<0.05) in all treatment groups, this can be seen from the P-value <0.05, with the group of rats receiving the highest concentration of ointment (10%) showed the highest average, namely hydration 49.60%, collagen 40.20%, and elasticity 68.20%. Changes in hydration levels, collagen, and skin elasticity before and after treatment also showed significant changes (P-value < 0.05) with the highest changes found at a concentration of 10%, namely hydration 88.40%, collagen 60.0%, and elasticity 68.20%. In conclusion, the results of this study showed that administration of avocado peel extract ointment could increase hydration, collagen, and skin elasticity levels compared to controls groups, positively correlated with the increase of the duration and the quantity of avocado peel extract ointment were given. The best formulation that gives the most significant effect is 10% avocado peel extract ointment by increasing levels of hydration, collagen, and elasticity the most significantly.

Avocado seed starch was extracted to prepare a biodegradable plastic film with enset cellulosic reinforcement and glycerol plasticiser. The characterisations were made in detail. Fourier transform infrared (FTIR) spectroscopy, differential scanning calorimeter (DSC), scanning electron microscopy (SEM), X-ray diffraction (XRD), rheometer, and Rapid Visco Analyser (RVA) techniques were employed to characterise the physicochemical properties of avocado seed starch, enset cellulosic, and the blend. Starch and enset cellulosic extraction yields are 18.3 ± 0.02% and 67.5 ± 0.08%, respectively. As a result, avocado seed starch and enset cellulosic blend can be used as alternative raw materials to develop biodegradable plastics.

This study investigates the extraction of avocado peel oil from avocado peel using a soxhlet extractor at different extraction times, temperatures, and solvent to avocado peel ratios using hexane solvent. The time for extraction ranges from 2 to 5 h, the extraction temperature ranges from 60 to 70°C at a temperature deviation of ± 2°C, and the hexane to avocado peel ratio ranges from 4 to 5 ml/g. Thus, the study reveals that the maximum amount of 29.93% w/w avocado peel oil was extracted at 3 h of extraction, at the boiling point of hexane, and at a 5 ml/g of hexane to avocado peel ratio. For varying extraction temperatures at constant hexane to avocado peel ratio, the optimum avocado peel oil was obtained at 70 ± 2℃ extraction temperature and 4.5 h of extraction time. Finally, the obtained oil was characterized for its physicochemical properties, from which an acid value of 2.8 mg KOH/g of oil and a free fatty acid of 1.4% were obtained from the study.
