Chemical composition, antioxidant, anti-lipooxygenase, antimicrobial, anti-parasite and cytotoxic activities of Polyalthia longifolia seed oil

Essential Oils of the Leaf and Stem of Polyalthia viridis Craib and Their Biological Activities

“…Regarding the genus Polyalthia, antimicrobial examinations have only been focused on P longifolia. 12,13 The EOs of this plant inhibited the growth of 2 micro-organisms, S aureus ATCC-29213 and C albicans ATCC-10231, with MIC values of 78 μg/mL. 13 This is the first report of antimicrobial activity of a Vietnamese Polyalthia species.…”

“…11 The EOs of Polyalthia species have displayed valuable pharmacological activities. The oil of Nigerian P longifolia seed showed potential for antioxidative, anti-inflammatory, antiparasitic and cytotoxic activities, 12 whereas the seed oil of this plant collecting from India showed an MBC/MFC value of 39.0 µg/ mL against 2 bacterial species, Streptococcus mutans and Staphylococcus aureus. 13 In the DPPH radical scavenging assay, the bark EO of P suaveolens had an SC 50 value of 0.71 µg/mL, which was better than that of the bark EO of Enantia chlorantha (SC 50 8.0 µg/mL).…”

Rapid Characterization of Chemical Components in Edible Mushroom Sparassis crispa by UPLC-Orbitrap MS Analysis and Potential Inhibitory Effects on Allergic Rhinitis

“…Fragment ion m / z 99.0445 [M – 144 + H] + was derived from the cyclization of the detached side C-chain. In a similar way, the other 33 alkaloids were identified according to their molecular mass, formula, MS/MS fragments, and related literatures, including arginine (peak 1) [29], ethyl- l -glutaminyl- l -threonine (peak 4) [30], 5′-deoxy-5′-methylthioadenosine (peak 12) [6], leucylproline (peak 13) [31], 2-aminooctanedioic acid (peak 16) [32], 2-amino-1,3-dodecanediol (peak 36) [33], stellarin C (peak 37) [34], 2-amino-1,3,4-tetradecanetriol (peak 39) [35], tuberostemonine (peak 40) [36], salternamide d (peak 41) [37], 3-(acetyloxy)-17-(benzoyloxy)-7-[ O -(phenylmethyl)oxime] androst-5-en-7-one (peak 45) [38], antrodin d (peak 50) [39], 1-(18-benzamido-3β-hydroxy-5α-androstan-17β-yl)-3-phenyl-2-propen-1-one (peak 52) [40], 3-cyclohexene-1-butyraldehyde-3-hydroxy-α-isopropyl-1-methyl-2-oxo-disemicarbazone (peak 54) [41], antrodin C (peak 59) [39], 2-amino-1,3,4-trihydroxyoctadecane (peak 66) [42], 2-amino-1,3-hexadecanediol (peak 77) [43], stachybotrin G (peak 78) [44], 2-methyl-6-(11-oxododecyl)piperidin-3-yl acetate (peak 82) [30], 2-methyl-6-(13-oxotetradecyl)piperidin-3-yl acetate (peak 86) [30], oleoylethanolamide (peak 87) [45], hurghamide D (peak 88) [46], 2-amino-1,3,4-octadecanetriol (peak 91) [47], oleamide (peak 94) [48], hexadecanamide (peak 97) [49], veracintine (peak 99), 2-nonadecananone- O -methyloxime (peak 101) [50], 4-azacholest-5-en-3-one (peak 102) [51], N-(2-phenylethyl)hexadecanamide (peak 103) [52], stearamide (peak 104) [53], thraustochytroside A (peak 105) [54], rhizoleucinoside (peak 106) [55], and erucamide (peak 107) [56]. Among these alkaloids, except 5′-deoxy-5′-methylthioadenosine, antrodin D, and antrodin C, all other 31 compounds were identified from the genus of Sparassis for the first time.…”

“…As shown in Figure S2, the deprotonated molecular ion of citric acid ( 2 , peak 3) [56] was observed at m / z 191.0195 [M − H] - in negative ion mode, which could easily yield the MS/MS fragment ion m / z 173.0089 [M – 18 − H] - after dehydration, and then the latter one could yield the fragment m / z 129.0192 [M – 62 − H] - through decarboxylation (losing CO 2 ). After that, by dehydration, the smaller but most abundant fragment ion m / z 111.0086 [M – 80 − H] - was produced from the fragment m / z 129.0192, or by the secondary decarboxylation at a higher collision energy, the fragment m / z 82.0295 [M – 62 − H] - was formed.…”

“…For the other types of compounds with various structures, the fragmentation patterns included but were not confined to dehydration, decarbonylation, decarboxylation, ring-opening and rearrangement. Finally, in total 21 other compounds were identified or tentatively identified, including ribono-1,4-lactone (peak 5) [56], citric acid monomethyl ester (peak 6) [90], crispacolide (peak 10) [91], methyl-2, 4-dihydroxy-6-methylbenzoate (peak 18) [10], sparoside A (peak 27) [6], methyl 2,4-dihydroxy-3-methoxy-6-methylbenzoate (peak 28) [6], methyl dihydroxymethoxy-methylbenzoate (peak 30) [10], sparassol (peak 33) [10], glucitol (peak 34) [10], dulcitol (peak 35) [57], xanthoangelol (peak 42) [92], 4-hydroxyderricin (peak 51) [92], butylated hydroxyanisole (peak 53) [93], armillarin (peak 62) [94], nicandrose E (peak 64) [95], 1,3-di(isobutoxycarbonyl)-2,4,4-trimethylpentane (peak 65) [96], 3-hydroxy-2-[[(9Z)-1-oxo-9-hexadecen-1-yl]oxy]propyl β- d -galactopyranoside (peak 70) [97], 1-(9-octadecenoate)-β- d -glucopyranose (peak 72) [98], 2,3-bis(4-hydroxy-3-methoxybenzyl)butane-1,4-diylditetradecanoate (peak 75) [99], linolenic acid ethyl ester (peak 84) [100], and 2,2′-methylenebis(4-methyl-6-tert butylphenol) (peak 92) [101].
