“…The DPPH radical scavenging activity was in the order BHA > DCPAP > CPAP. Earlier Ma et al [9] also reported superior antioxidant activity for the dichloromethane extract of pyroligneous acid from Rosmarinus officinalis leaves. The DPPH radical scavenging potential of guaiacol and syringol derivatives derived from lignin is already well established [32] and these compounds were shown to exhibit higher scavenging activity than BHA, BHT, Ascorbic acid and ␣-tocopherol [3].…”

“…However the major phenolic compound identified in bamboo PA was phenol (19%) followed by 2,6-dimethoxy phenol (13.2%), 2-methoxy phenol (8.6%), 1,2-Benzenediol (7.3%) and 4-methyl phenol (5.9%) [31]. PA from rosemary had compounds such as 1S-␣-Pinene, Camphene, Eucalyptol and D-Limonene which are characteristic of the biomass used [9] however in the case of PA from pineapple plant waste no such characteristic compounds were detected. Phenolic compounds namely Phenol (pungent), alkyl phenol derivatives (pungent and cresolic flavor), guaiacol (sweet smoky somewhat pungent), alkyl guaiacol derivatives (sweet, smoky, woody), syringol (smoky) and alkyl syringol derivatives (mild, heavy, burnt) contribute to the aroma and flavor of pyroligneous acid [11].…”

“…The wood types and pyrolysis temperature are primary factors for wood vinegar yield [7][8]. For example, Ma et al [9] reported that wood vinegar yield from Rosmarinus officinalis leaves was 25%, whereas those from Eucalyptus urograndis and Mimosa tenuiflora wood were 37.8 and 30.5%, respectively [10]. Ratanapisit et al [11] found that the maximum wood vinegar yield from rubber wood at a pyrolysis temperature of 550 °C was 27.45%.…”

“…Sabe-se que a composição química dos extratos obtidos a partir do processo de pirólise é dependente de características dos materiais de origem bem como das condições de carbonização (Ma et al, 2013). Materiais lenhosos -ricos em lignina e celulose -quando submetidos a reações pirolíticas, são termicamente degradados em cetonas, álcoois, e derivados de furano e pireno, podendo também ser convertidos em compostos fenólicos (Wei, Ma e Dong, 2010;Souza et al, 2012).…”
