“…Its Korean name is chamchwi, and it is called chwinamul by the Korean people (Lee, 1989;Kwon et al, 2000a). AS, both as a whole extract and individual components, has been reported to have many beneficial biological attributes, such as anti-inflammatory, antioxidant, and anti-adipogenic properties (Kim et al, 2009;Kim et al, 2015;Choi et al, 2020). It is rich in vitamin C, calcium, iron, and β-carotene (Chung et al, 1993).…”

In mountainous regions, wild herbs which can also be edible in nature for humans and animals possess a wide array of biologically diversified properties. It is because of the fact that due to the cold weather of mountains; they are enriched in certain kinds of phytochemicals such as anti-oxidants, anti-inflammatory and many more. One such kind of an herb is Aster scaber (AS) in Korean. It is a widely cultivated culinary herb in Korean peninsula and used as a side dish in Korean culinary cuisine. In view of its extensive use in cuisine, we geared to unravel the anti-oxidant and anti-inflammatory effects of AS in murine alveolar macrophage cell line (MH-S). 2,2'-Azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) and 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) assays revealed a dose dependent (7.8~1,000 μg/mL) inhibition of oxidation by AS 70% ethanol (ASE) extract as compared to Trolox and Ascorbic acid respectively. Nitric oxide assay (NO) showed a dose dependent decrease (5~40 μg/mL) in MH-S cells with ASE when stimulated with Coal Fly Ash (CFA). Moreover, this dose for NO reduction was also found to be least cytotoxic for cells as determined by cellular viability (MTT) assay. The gene expression of pro-inflammatory mediators (iNOS and COX-2) and cytokines (IL-6 and IL-1β) and were also dose dependently inhibited by ASE in MH-S cells through RT-PCR. Therefore, in light of these findings, AS exhibited a strong anti-oxidant and anti-inflammatory agent. These results also justify the extensive use of this mountainous herb in culinary practices for beneficial effects on human health.

The dissipation kinetics of spirodiclofen and tebufenpyrad after their application on Aster scaber Thunb were studied for 10 days, including the pre-harvest intervals. Spirodiclofen and tebufenpyrad were used in two greenhouses in Taean-gun, Chungcheongnam province (Field 1) and Gwangyang-si, Jeollanam province (Field 2), Republic of Korea. Samples were taken at 0, 1, 3, 5, 7, and 10 days after pesticide application. The method validations were performed utilizing liquid chromatography (LC)-tandem mass spectrometry (MS/MS). The recoveries of the studied pesticides ranged from 82.0–115.9%. The biological half-lives of spirodiclofen and tebufenpyrad were 4.4 and 3.8 days in Field 1, and 4.5 and 4.2 days in Field 2, respectively. The pre-harvest residue limits (PHRLs; 10 days before harvesting) of Aster scaber were 37.6 mg/kg (Field 1) and 41.2 mg/kg (Field 2) for spirodiclofen, whereas the PHRLs were 7.2 (Field 1) and 3.6 (Field 2) for tebufenpyrad. The hazard quotient for both pesticides at pre-harvest intervals was less than 100% except in the case of spirodiclofen (0 day).

This study aimed to establish the optimal drying conditions that minimize quality changes during hot air drying for Chamchwi, a leafy vegetable. Drying temperature (50, 60, 70°C) and time (60, 150, 240 min) were set as independent variables, and the physicochemical characteristics were analyzed after drying. A central composite design was used to design 13 experimental points, and the dependent variables included moisture content, water absorption capacity, chromaticity, strength, total polyphenols, total flavonoids, β-carotene, total chlorophyll, chlorophyll a, chlorophyll b, and volatile aroma components. The optimization variables were moisture content, water absorption capacity, leaf, and stem strength, a* value, and total flavonoid content with a model P-value of 0.05 or less and R 2 values of 80% or more. The optimized drying conditions were a temperature of 56.87°C and a time of 156.36 minutes. The corresponding predicted values were moisture content 10.27%, water absorption capacity 12.54%, leaf strength 47.44 kg/cm 2 , stem strength 51.86 kg/cm 2 , a* value of −2.54, and total flavonoid contents 11.25 μg/mL.
