Abstract

Kanker kulit melanoma merupakan satu dari sembilan belas kanker yang sering terjadi di seluruh dunia. Kebutuhan akan adanya alternatif zat aktif tabir surya menjadi sangat penting terutama dari bahan alam laut yaitu anggur laut (Caulerpa sp.). Penelitian ini bertujuan untuk menentukan nilai SPF ekstrak cair anggur laut segar dengan metode ekstraksi yang berbeda. Metode ekstraksi dilakukan dengan dua cara yaitu maserasi dan microwave-assisted extraction (MAE) masing-masing dengan tiga jenis pelarut (etanol, air, dan etanol-air 1:1). Ekstrak cair yang dihasilkan diukur pH dan ditentukan nilai SPF secara invitro menggunakan spektrofotometer UV-Vis. Ekstrak cair anggur laut segar dengan nilai SPF in vitro tertinggi kemudian dianalisis aktivitas antioksidannya menggunakan metode DPPH. Ekstrak cair yang dihasilkan berbau amis, dan berwarna hijau dengan intensitas warna yang berbeda. Interaksi antara perlakuan metode ekstraksi dan jenis pelarut menunjukkan perbedaan signifikan terhadap nilai pH ekstrak cair anggur laut segar. Nilai SPF dari ekstrak maserasi etanol, air, dan etanol-air berturut-turut 0,583; 3,099; 2,911 sedangkan ekstrakMAE 3,807; 5,555; 4,979. Metode MAE menunjukkan nilai SPF in vitro yang lebih tinggi secara signifikan daripada maserasi tanpa melihat perbedaan pelarut.Hasil persentase penghambatan DPPH dari ekstrak MAE dengan pelarut etanol, air, dan etanol-air pada konsentrasi 106 mg/mL berturut-turut 33,85%; 22,99%; 17,44%. Aktivitas antioksidan ekstrak etanol dengan metode ekstraksi MAE lebih tinggi daripada ekstrak dengan pelarut lainnya namun tidak lebih tinggi dibandingkan dengan asam askorbat sebagai pembanding.

Abstract

Recent insights reveal that liver diseases influence not only hepatic function but also disrupt gut microbial balance through the gut–liver axis. The gut–liver axis establishes a bidirectional relationship between the intestines and the liver, allowing microbial by-products such as short-chain fatty acids (SCFAs) to influence liver function and health. Short-chain fatty acids are known to maintain intestinal epithelial integrity, reduce inflammation, and support liver function. Probiotic bacteria including Lactobacillus, Bifidobacterium, and Clostridium, are natural SCFA producers and may offer therapeutic potential for liver disease by targeting the gut-liver axis. This systematic review was conducted using the PRISMA 2020 methodology to identify and evaluate preclinical studies examining the impact of SCFA-producing probiotics on liver disease. We searched PubMed, Scopus, and Google Scholar from August to October 2023, using predefined inclusion criteria based on the PICO framework. The SYRCLE risk of bias tool was employed to evaluate potential biases. A total of 14 animal studies fulfilled the inclusion criteria and were incorporated into the final analysis. The included studies demonstrated that SCFA-producing probiotics improved liver function by reducing serum liver enzymes (ALT, AST), increasing tight junction proteins (occluding, ZO-1), modulating pro-inflammatory cytokines (IL-1β, IL-6, TNF-α,), and improving lipid metabolism. These outcomes were mediated by increases in SCFA levels and improved gut barrier integrity in models of NAFLD, ALD, NASH, and autoimmune hepatitis. These findings support the promising potential of SCFA-producing probiotics as adjunctive therapies for liver disease through modulation of the microbiota-gut-liver axis. Yet, continued research is needed to determine strain-specific efficacy, optimal dosage, long-term safety, and clinical applicability. Future research should also explore personalized probiotic strategies and the integration of probiotic therapy into standard liver disease management.
