This research aimed (1) to study the main element of thousand year old mud and types of color-giving substances from marigold flowers and (2) to study the causes of silk color change from dark yellow to dark green at Bankhokmuang, Chorakhemark Sub-district, Prakhonchai District, Buriram Province. Firstly, the researcher studied the element of the mud from Barai Prasat Muang Tam and Barai Kuti Ruesi, using EDXRF. Secondly, the researcher studied types of phytochemicals in marigold extract using HCl solution and NaOH solution. Finally, the researcher dyed the silk with marigold flower extract mixed with alum and dyed it with iron ion solution and the mud solution from both sources. The results showed that both muds had the highest amount of Fe2O3, 64.03% of Barai Prasat Muang Tam mud and 44.22% of Barai Kuti Ruesi mud. The coloring substance of marigold extract was flavonoids and had good water solubility. Then the researcher dyed the silk with marigold flower extract mixed with alum because alum contained Al3+ions. The silk was dark yellow. The silk was divided into three groups to be dyed again. The first group was dyed with 1,000 ppm iron ion solution. The second group was dyed with a solution of Barai Prasat Muang Tam mud. The third group was dyed with a solution of Barai Kuti Ruesi mud. All group color changed from dark yellow to dark green. Thus, iron ion solution and both of Barai mud solution were rich in iron ion. This complex compound could form with flavonoids which made golden yellow color turns dark green and sticks to silk threads. It was also water insolubility. The color was not faded. All groups had different shade values at the significance level of 0.05. GRAPHICAL ABSTRACT HIGHLIGHTS Study the main element of thousand year old mud Study area at at Bankhokmuang, Chorakhemark Sub-district, Prakhonchai District, Buriram Province. Causes the color of the silk thread to change from yellow to dark green

“…Previous studies on the volatile substances in the flowers and leaves of marigold have indicated that there is a large proportion of various terpenoids, which produce the terpenes volatile organic compounds (VOCs) ( Ogunwande and Olawore, 2006 ). Few flavone derivatives have been identified in different marigold species, namely, luteolin and luteolin 7-O-glucoside from Tagetes multiflora ( Abdala, 2003 ), and chrysocriol-7-O-(6-O-β-L-arabinofuranosyl)-D-glucopyranoside from Tagetes patula ( Kurkina et al., 2021 ). Similarly, carotenoids, mainly β-carotene and zeaxanthin, were found in Tagetes species ( Breithaupt et al., 2001 ).…”

The current study placed an intense emphasis on the excess discharge of agro-based industrial effluent and the use of plant extract antimicrobials to inhibit the growth of pathogens in crop plants. An effluent (treated and untreated) from the marigold flower processing industry has been identified for the presence of volatile and semi-volatile organic compounds, and a total of 18 in treated effluent and 23 in untreated effluent were found using gas chromatography–mass spectrometry. A total of 13 classes were identified, which include carboxylic acid, phenols, esters, alkanes, alkenes, alcohols, cyanide, heterocyclic, flavonoids, aldehydes, polycyclic aromatic, cycloalkanes, and cycloalkenes. A principal component analysis with varimax rotation was applied to discern the abundance of identified compounds under each class. An in vitro antifungal bioassay was conducted using effluents at three different concentrations against plant pathogens (Alternaria alter nata, Sclerotium rolfsii, Rhizoctonia solani, Pythium aphanidermata, Fusarium oxysporum, and Colletotrichum gloeosporioides). The study proved that treated and untreated effluents clearly inhibited the growth of fungal pathogens by 10 to 32% and 37 to 92%, respectively. The findings suggest that marigold flower effluent can be a promising resource for developing new plant protection methods that are effective against pathogenic fungi.

Standardization of a Formulation of Timogar and Ferula Assa-Foetida Dry Resin Extract and its Biological Activity

et al. 2021

A dry extract of Ferula assa-foetida L. gum-resin was obtained. A formulation was developed on the basis of the extract and timogar preparation. Esters were qualitatively determined using the reaction with vanillin solution (1%) in conc. H 2 SO 4 ; polysaccharides, with phenol in the presence of conc. H 2 SO 4 ; coumarins, by TLC using umbelliferone standard. The quantitative content of timogar was determined using UV spectrophotometry; total phenolic compounds, the Folin-Ciocalteu method. The flavonoid content was also quantitatively determined. The formulation was standardized for description, solubility, mass loss on drying, heavy metals, authenticity (timogar, esters, polysaccharides, and coumarins), and quantitative content (timogar, total phenolic compounds, and flavonoids). The timogar content was 0.009 -0.011%; total phenolic compounds, at least 75%. The flavonoid content was quantitatively determined using spectrophotometry and the reaction with an AlCl 3 solution (10%) and should be at least 89% when recalculated using cynaroside as a standard. Experimental studies of acute and chronic toxicity showed that the proposed formulation was nontoxic and could be classified as hazard class 6 (relatively harmless). The immunostimulatory activity of the formulation exceeded by 1.3 times that of timogar alone.
