“…Alkaloids, which are found in roots, stems, leaves or seeds of plants and expressed various biological properties such as anti-inflammatory, antioxidants, antitumoral and antibacterial. [51][52][53] Flavonoids are phenolic compounds and widely distributed in plants. Flavonoids are important for plant pigments that composes flavonone, flavone, isoflavone, flavonol, catechin, naringin and anthocyanins, which are found in vegetables, fruits and some beverages such as tea and wine.…”

Background: Some of Zingeberaceae are not widely used for medicine of food, although in Thailand have been used them for many reasons about health or the diet. This study evalued the phytochemicals and anti-tyrosinase activities of 16 plant species of Alpinia, Amomum, Curcuma, Etlingera and Kaemferia (Zingiberaceae). Methods: The extractions of dried powdered rhizomes were performed using n-hexane, ethylacetate and ethanol. Percentage extract yield of the samples varied among species and solvent extracts. Chemical groups (alkaloids, flavonoids, tannins, polyphenols, steroids and terpenoids) were identified using phytochemical screening. The total phenolic contents (TPC) were analyzed using the Folin-Ciocalteu's reagent, while antioxidant activities were detected using 2,2-diphenyl-1picrylhydrazyl (DPPH) and the 2,2'-azino-bis (3-ethylbenzothizoline-6-sulphonic acid) (ABTS .+ ). The anti-tyrosinase was expressed to the half maximal inhibitory concentration (IC 50 ) value (mg/mL). Results: The ethyl acetate extract of Amomum showed the highest value of TPC. The strongest antioxidant activity were found in Amomum and Kaemferia extracts, while ethyl acetate and ethanol extracts of all samples have a better antioxidant properties than the n-hexane extracts. On the other hand, the n-hexane extracts have the highest anti-tyrosinase potential in all samples and of these, Curcuma extracts were the best group. Conclusion: Our research indicated that plants of the Zingiberaceae would be new sources of antioxidants and anti-tyrosinase for further natural product developments in cosmetics, food or nutraceuticals.

“…As is commonly known, the extraction of the non-polar compounds is usually performed with organic non-polar solvents such as acetone, hexane, chloroform, or a mix of them. While, the polar compounds are usually extracted with polar solvents such as water, ethanol, methanol, alone or in combination (Hasbay & Galanakis, 2018;Saldaña, Gamarra, & Siloto, 2009). The general scheme of extraction of bioactive compounds from galangal is shown in Figure 4.…”

“…Free radicals, and reactive oxygen and nitrogen species can cause oxidative stress resulting in damage to several biomolecules, and therefore leads to chronic disease and serious illness [6]. Plants, including vegetables, fruits, herbs, and cereals, have various bioactive compounds that have anti-diabetic, antibacterial, anti-cancer, anti-atherogenic, and anti-inflammatory effects [7]. The administration of Senna alata (S. alata) extract reported to improve the impaired lipid metabolism in HFD-induced obese mice by the reducing of serum lipid concentrations and hepatic triglycerides content [8].…”

The present study was conducted to investigate the total phenolics, total flavonoid, and Trolox equivalent antioxidant capacity of 9 commonly used medicinal plants and herbs among Arabs nation namely, Trachyspermum ammi (Apiaceae) seeds, Ferula assa-foetida (Apiaceae) dried latex, Elettaria cardamomum (Zingiberaceae) fruit 1, Senna alexandrina (Caesalpinioideae) Leguminosae leaves, Adenium obesum (Apocynaceae) leaves, Elettaria cardamomum (Zingiberaceae) fruit 2, Trigonella foenum-graecum (Leguminosae) seeds, Lepidium sativum (Brassicaceae) seeds, Ziziphus spina-christi (Rhamnaceae) fruit, and Nigella sativa (Ranunculaceae) seeds.The methanol extract of each plant was obtained by dissolving 2g of plant powder in 20 ml methanol-water (4:1v/v) to overnight at room temperature. The supernatants were concentrated by using a rotary evaporator. Residues of each extract were dissolved in distilled water and the final volume was recorded. A serial dilution of 10, 100, 1000, and 5000 were made.
