“…In another study made by Mota et al [ 49 ], it was evaluated SPF of Psidium guajava ethanolic extract and they found SPF = 1. Similarly, Mota et al [ 50 ] evaluated SPF of Nephelium lappaceum L. ethanolic extract (peels) and its SPF = 0.4.…”

Secondary metabolite production by plants is influenced by external environmental factors that can change depending on the seasons, which makes it important to know how the plant, through its metabolism, is able to adapt to these variations. Mentha x villosa and Plectranthus amboinicus present in their chemical composition polyphenols, and through previous studies, it has been seen that these two species present promising in vitro photoprotective activity. The aim of this study was to evaluate seasonal alterations in photoprotective and antioxidant activities and the influence of factors such as precipitation levels and sun radiation incidence. Thus, polyphenol quantification, cromatographics (HPLC-DAD) and multivariate (PCA) analyses of extracts of the two species through twelve months were done. It was observed that the best months for photoprotective and antioxidant activities were September for M. villosa and July for P. amboinicus (SPF = 14.79). It was possible to conclude that solar radiation more clearly influences the production of phenolics and the increase of SPF in M. villosa, in addition to favoring the antioxidant activity of the two species, while precipitation seems to have no influence.

“…membutuhkan waktu maserasi selama dua bulan pada suhu kamar menggunakan pelarut air untuk mengisolasi tanin dari jerami padi, daun teh, daun lengkeng dan daun pisang [3]. Selain itu, beberapa penelitian sebelumnya terkait isolasi senyawa bioaktif dari Psidium guajava menggunakan metode maserasi juga menunjukkan bahwa metode tersebut memerlukan waktu ekstraksi yang panjang [9][10][11][12][13]. Waktu maserasi yang panjang mengakibatkan metode ini tidak efisien untuk industri.…”

Daun Psidium guajava adalah bahan baku alami yang mengandung senyawa bioaktif, salah satunya adalah tanin. Tanin digunakan pada berbagai industri seperti tekstil, farmasi, kosmetik, dan makanan. Penelitian ini bertujuan untuk mempelajari pengaruh waktu ekstraksi dan rasio solid-liquid terhadap kandungan tanin ekstrak daun Psidium guajava. Daun segar dan kering diekstraksi dengan etanol dengan perbandingan solid-liquid 1/20 dan 1/60 (b/v). Temperatur ekstraksi pada suhu 80 °C dan waktu ekstraksi 30, 45, 60, 75, dan 90 menit. Kadar tanin tertinggi diperoleh pada pada waktu 60 menit dan perbandingan solid-liquid 1/20 (b/v) masing-masing sekitar 17 % dan 12 % untuk sampel daun kering dan basah. Sebaliknya, penambahan rasio pelarut tidak memberikan dampak yang signifikan terhadap peningkatan kandungan tanin yang diekstraksi. Penelitian ini menunjukkan bahwa peningkatan waktu ekstraksi meningkatkan perpindahan massa tanin sampai tercapai tahap kesetimbangan.

“…Previously, the influence that ultraviolet solar radiation exerts in premature skin aging has been exposed; nonetheless, a large amount of other serious health problems can be triggered: intracellular DNA damage, oxidative stress resulting from the photochromic generation of ROS and degradation of ECM components, such as collagen, fibronectin, elastin and proteoglycans, among others. All these physiological changes can cause multiple effects on the immune system and often generate or sustain UV-induced neoplasms with decreasing skin hydration and elasticity [ 118 ].…”

The increasing production of tropical fruits followed by their processing results in tons of waste, such as skins or seeds. However, these by-products have been reported to be rich in bioactive compounds (BACs) with excellent properties of interest in the cosmeceutical industry: antioxidant, anti-aging, anti-inflammatory, antimicrobial and photoprotective properties. This review summarizes the tropical fruits most produced worldwide, their bioactive composition and the most important and studied therapeutic properties that their by-products can contribute to skin health, as well as the different approaches for obtaining these compounds using techniques by conventional (Soxhlet, liquid-liquid extraction or maceration) and non-conventional extractions (supercritical fluid extraction (SFE), ultrasound-assisted extraction (UAE), microwave-assisted extraction (MAE), pressurized liquid extraction (PLE) and two-phase aqueous system), followed by their identification by HPLC-MS or GC-MS analysis. Moreover, this work encompasses several studies that may prove the effects of seeds and skins from tropical fruits against oxidative stress, hyperpigmentation, acne, aging or UV radiation. Therefore, the investigation of functional components present in tropical fruit by-products under a circular bioeconomy model could be of great interest for the cosmeceutical industry and a very promising option for obtaining new cosmeceutical formulations.
