“…Compound 3 was identified for the first time from pepper leaves. Anthocyanins have been categorized as the most important group of water-soluble natural pigment in crops such as fruits, vegetables, and flowers. − These natural pigments are beneficial to the food industry due to their good properties as food colorants and beneficial human health effects, such as antioxidant, anti-inflammatory, anticancer, antidiabetic, and antiartherogenic properties. , Compound 2 is well-known as a treatment material for its antihistamine, antiviral, antioxidative activity, and DNA-protective activity. ,, Compound 6 is reported on for its antiproliferative, anti-LDL oxidative, and cytotoxic activity, as well as its gelatinase and collagenase inhibition, antifeedant activity, and anti-HBV activity. − Compound 7 is well-known as a treatment material for its anticomplement, anti-inflammatory, liver protection, and antibacterial activities. − Compound 8 is well-known as a treatment material as an antifungal, cytotoxic, antibacterial, and anti-HIV agent. − Finally, compound 9 is well-known as a treatment material due to its antibacterial nature . Thus, they represent an effective antioxidant source for commercial food and pharmaceutical uses due to their content, disease treatment, and strong radical-scavenging activities.…”

The antioxidant properties and phenolic profiles were first investigated in this paper on the leaves of three red pepper cultivars, Blackcuban (BCPL), Hongjinju (HPL), and Yeokgang-hongjanggun (YHPL). Of the ethanol extract of the three cultivars, BCPL showed potent antioxidant activities against the 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) and the 2,2-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical. Nine antioxidative compounds from the red pepper leaves were isolated and identified as one polyamine phenolic conjugate, N-caffeoylputrescine (1); three chlorogenic acid derivatives, 5-O-caffeoylquinic acid (2), 5-O-caffeoylquinic acid methyl ester (4), and 5-O-caffeoylquinic acid butyl ester (9); one anthocyanin, delphinidin-3-[4-trans-coumaroyl-l-rhamnosyl(1→6)glucopyranoside]-5-O-glucopyranoside (3); and four flavone glycosides, luteolin-7-O-apiofuranosyl(1→2)glucopyranoside (5), luteolin-7-O-glucopyranoside (6), apigenin 7-O-apiofuranosyl(1→2)glucopyranoside (7), apigenin-7-O-glucopyranoside (8). 1 and 3 had the greatest potential for radical-scavenging activity and HepG2 cells protecting effect against oxidative stress. BCPL exhibited the highest content of 1 and 3. Of the three cultivars BCPL may be considered a good source of antioxidants.

“…The reaction mixture was partitioned between water and hexane. The hexane extract was analyzed by GC [ 15 ] (detector temperature: 280 °C; injector temperature: 250 °C; temperature gradient: start at 160 °C, hold for 5 min, increase to 280 °C at 5 °C/min, hold for 10 min). The authentic samples were analyzed in the same way.…”

In the course of a phytochemical and chemotaxonomical investigation of Castanopsis species (Fagaceae), three new phenolic compounds, (3R,1′S)-[1′-(6″-O-galloyl-β-d-gluco-pyranosyl)oxyethyl]-3-hydroxy-dihydrofuran-2(3H)-one (1), (2R,3S)-2-[2′-(galloyl)oxyethyl]-dihydroxybutanoic acid (2), and (3S,4S)-3-hydroxymethyl-3,4-dihydro-5,6,7-trihydroxy-4-(4′-hydroxy-3′-methoxyphenyl)-1H-[2]-benzopyran-1-one (3) were isolated from the fresh leaves of Castanopsis fargesii. In addition, a known phenolic glycoside, gentisic acid 5-O-α-l-rhamnopyranosyl-(1→2)-β-d-glucopyranoside (4) was also isolated and identified. Their structures were elucidated by means of spectroscopic methods including one- and two-dimensional NMR techniques.

“…Being soluble in lipids accelerates its rate of penetration into the insect hemocoel (body cavity). The penetration rate of bruceine A through the cuticle depends on cuticle structure and thickness [25]. Toxic substances generally tend to penetrate through larval body parts that are thinly coated with cuticle; examples of such body parts include intersegmental membranes, membrane joints, and chemoreceptors on the tarsus [26].…”

Objective: This study aimed to determine a target of action of bruceine A on the basis of its morphological and histological effects on the larvae of Aedes aegypti Linnaeus.Methods: Bruceine A was isolated from Brucea javanica (L.) Merr. seeds in accordance with the Mangungsong method. Larvae of A. Aegypti (L.) in instar III to the beginning of instar IV were treated with various concentrations of bruceine A. The negative control group did not receive any treatment, whereas the positive control group received 1 ppm temefos. Dead larvae were collected after 24 h of treatment for the examination of morphological and histological changes.Results: The negative control group did not exhibit any morphological and histological changes. Larvae treated with bruceine A, however, had visible damaged heads, cuticles, digestive and respiration tracts, respiratory siphons, and setae, and they were smaller than normal larvae. Larvae treated with temefos exhibited gastrointestinal damage, narrowed breathing tubes, cuticle damage, and detached/damaged seta feathers. The necrosis of gastrointestinal epithelial cells was the major histological change exhibited by larvae treated with various concentrations of bruceine A or 1 ppm temefos.Conclusion: The targets of action of bruceine A in A. aegypti (L.) larvae are the head/caput, cuticle, setae, siphon, and gastrointestinal and respiratory tracts.
