Eleven Species

The Genus Neocrangon Zarenkov, 1965 was one of the most poorly reported genera in the caridean family Crangonidae. Zarenkov (1965) divided the genus Crangon Fabricius, 1758 into two subgenera, ie. Crangon s. str. and his new subgenus Neocrangon, and designed eleven species in the latter, the type species was Crangon communis Rathbun, 1899. Squires and Figueira (1974) followed Zarenkov (1965) and accepted the subgenus Neocrangon. Kuris & Carlton (1977) raised Neocrangon as a separated genus and recognized that only five species, which has two gastric spines as that in the type species from the eleven species designed by Zarenkov (1965), belonging to Neocrangon. The five species were: Neocrangon communis (Rathbun, 1899), N. abyssorum (Rathbun, 1902), N. resima (Rathbun, 1902), N. joloensis (De Man, 1929) and N. zacae Chace, 1937. Then, Wicksten (1996) synonymized N. zacae Chace, 1937 as a junior synonym of N. resima (Rathbun, 1902). Up to date, four species have been recognized in the genus Neocrangon Zarenkov, 1965.When we sorted the crangonid shrimp specimens deposited in the collections of the Institute of Oceanology, Chinese Academy of Sciences, Qingdao (IOCAS), eight specimens belonging to Neocrangon collected by trawling in the China-America Continental Shelf Cooperative Investigation of the East China Sea (1978–1979) were separated out and were identified belonging to an undescribed species. Based on the specimens, we describe a new species in the present paper.

The objective of this work was to study the effect of the addition of polyphenolic peanut skin extracts (PSE) and oregano essential oil (OEO) on the microbiological, chemical, and sensory properties of frankfurter-type sausages during storage. Seven treatments were prepared: control sample (C: without additives); sausage with commercial additives (F); with OEO (O); with Runner PSE (R); with Virginia PSE (V); with OEO and Runner PSE (OR), and with OEO and Virginia PSE (OV). Consumer tests and general composition analysis were performed on the fresh products (sausages without storage). Sausages were stored at 4 °C during 37 days and samples were extracted at days 0, 12, 23, and 37 for microbiological, chemical (peroxide value and conjugated dienes), and sensory descriptive analysis. All sausages had low fat content (3.36 g/100g) and good colour, flavour and texture acceptance scores by consumers (between 57 on a 9-point hedonic scale). The absence of commercial additives (nitrite, nitrate, and other compounds) affected the sausage characteristic colour, reducing the consumer’s acceptance. The treatments with natural additives had less microbiological and chemical deterioration compared to control sample. The results suggest peanut skin extracts and oregano essential oil can replace commercial additives as preservatives in sausages.

Calocedrus Formosana

Calocedrus formosana (Cupressaceae) is one of the five precious woods of Taiwan. In this study, we investigated the anti-melanogenic activity of C. formosana wood essential oil (CFEO) and its bioactive components in vitro. Initially, CFEO exhibited strong mushroom tyrosinase activity in the cell-free mushroom tyrosinase assay system with an IC50 value of 2.72 µg/mL. Next, treatment with CFEO significantly as well as dose-dependently reduced a combination of a-melanocyte-stimulating hormone and forskolin (a-MSH-FSK)-induced melanin synthesis in B16-F10 cells. Indeed, 80 mg/mL CFEO completely inhibited melanin production, which is similar to that of control cells. Further studies revealed that treatment with CFEO significantly inhibited melanogenesis regulatory proteins, including TRP-1, TRP-2, and MITF, whereas tyrosinase was unaffected by either a-MSH-FSK or CFEO. In addition, the composition of the CFEO was characterized. The major components of CFEO were α-terpineol (23.47%), shonanic acid (10.45%), terpinen-4-ol (12.23%), thymol (5.3%), piperitone (3.44%), berbenone (2.81%), thujic acid (1.65%), and chaminic acid (0.13%). Among them, shonanic acid (1), thujic acid (2), and chaminic acid (3) were uncommon constitutes in essential oils, which could be the index compounds of CFEO, and the structure of these compounds were confirmed by spectral analysis. Furthermore, we found that thymol is an active ingredient responsible for CFEO’s anti-melanogenic activity. Based on these results, we suggest that CFEO or thymol could be a potential candidate for the development of skin whitening products for cosmetic purposes.

Chamaecyparis obtusa Siebold & Zucc. f. formosana Hayata (Cupressaceae) is one of the treasured conifers in Taiwan. In this study, the wood essential oil of the species was extracted and its anti-inflammatory bioactivities analyzed. The composition analysis of the essential oil yielded a total of 57 compounds with α-terpineol (19.4%), τ-muurolol (16.9%), borneol (16%), and α-cadinol (10.9%) predominating. The anti-inflammatory assays of the essential oil suggest that C. obtusa f. formosana wood oil has no cytotoxicity, and was capable of inhibiting the expressions of tumor necrosis factor (TNF-α), IL-6, IL-1, pro IL-1β, NO, iNOS, and NLRP3 in murine macrophage cells. It was unable, however, to inhibit the expression of COX-2. Further investigation of the effect of the essential oil on the cellular signal transduction indicated that it was capable of inhibiting ERK1/2, JNK1/2 and p38; it also showed excellent inhibition against ROS. Thus, the overall results indicated that C. obtusa f. formosana wood oil had very good anti-inflammatory efficacies.
