“…Prasiola japonica thrives in a low-temperature, weakly alkaline environment with fast-flowing streams and can attach to rocks and other surfaces. It contains high levels of vitamins and minerals (Seo et al 2013) and has been evaluated as a potential candidate for devel-oping anti-tumor and anti-inflammatory drugs (Lee et al 2021). It is also used as a raw material in various foods, additives, medicines, and cosmetics (Park et al 2018(Park et al , 2022Rahmawati et al 2021).…”

Background: Prasiola japonica is a freshwater green algae species that can only be seen in Korea and Japan. The various conditions necessary for its growth and reproduction have not been fully elucidated. Therefore, in this study, we aimed to investigate conditions related to the growth and reproduction of P. japonica for the purpose of conserving and producing this species. We first examined differences in growth according to various conditions in different habitats to understand the growth environment of P. japonica. Results:The experimental results revealed that the optimal temperature for growth and reproduction of P. japonica was between 10°C-15°C, and the optimal light intensity was 1,000-1,500 lux. Furthermore, when Provasoli enriched seawater with iodine (PESI) agar was used, the growth of P. japonica was found to be at least 1.5-8 times greater than that of the general Sohan Valley water sample, and it also showed 2-4.5 faster growth rate to reach 30 μm. These results emphasize the importance of PESI agar in the culture of P. japonica, and are expected to be helpful in suggesting ways to utilize and conserve P. japonica resources. Conclusions: Through these research findings, we suggest new methods for conserving and producing P. japonica, highlight the importance of preserving the P. japonica ecosystem, and explore ways to utilize P. japonica resources. This research promotes the understanding and protection of P. japonica resources in Korea and beyond, and underscores the need for further research and conservation efforts.

“…Of them, loliolide is known to be an active component in green algae with various biological roles such as anti-aging, anti-viral, and anti-inflammatory activities [ 16 , 17 , 18 , 19 ]. So far, however, the effects of fresh water green algae components, loliolide and P. japonica ethanol extract (Pj-EE), on the skin have not been studied extensively [ 20 ]. In this study, we investigated oxidative stress-protective effects of loliolide and Pj-EE in human keratinocyte HaCaT cells.…”

Loliolide is a monoterpenoid hydroxylactone found in many algae, including fresh water green algae, Prasiola japonica. To date, loliolide and compounds in P. japonica have not been studied systematically with respect to skin pharmacology. In this study, we investigated oxidative stress-protective and anti-melanogenic effects of loliolide and P. japonica ethanol extract (Pj-EE), known to contain loliolide, in human keratinocyte (HaCaT) cells and mouse melanoma (B16F10) cells. Loliolide suppressed the transcription of genes encoding matrix metalloproteinases (MMPS), which were induced in HaCaT cells by hydrogen peroxide (H2O2) treatment. Loliolide and Pj-EE not only reduced the melanin secretion and content in B16F10 cells but also increased the expression of the antioxidant proteins nuclear factor (erythroid-derived 2)-like 2 (NRF2) and heme oxygenase-1 (HO-1) in HaCaT cells subjected to H2O2 treatment. Furthermore, loliolide and Pj-EE decreased expression of the anti-melanogenic protein microphthalmia-associated transcription factor (MITF) and tyrosinase in B16F10 cells subjected to α-melanocyte-stimulating hormone (α-MSH) treatment. Our findings demonstrate that loliolide and Pj-EE have antioxidant and anti-melanogenic effects on skin.
