Oleoresin Production and Turpentine Component of Pinus oocarpa and Pinus merkusii

Abstract

This study aims to determine differences in oleoresin production and the type and content of turpentine P. oocarpa and P. merkusii. The first stage of the research activity was to collect oleoresin obtained from 15 plants of each type of pine aged 14 years which were determined randomly. Determination of the type and content of phytochemicals, especially turpentine using Gas Chromatography-Mass Spectrometry by injecting gas-phase chemical isolates. The oleoresin tapping data were analyzed by paired t-test with a test level of 5% to determine the difference in the amount of oleoresin. The results showed that there was no difference in production capacity (p<0.05) between the two stands with an average oleoresin production per tree of 0.0127±0.002 g.d-1 (P. oocarpa) and 0.0183±0.003 g.d-1 (P. merkusii). The most important species in P. oocarpa consisted of: α-pinene (5.2%), ß-pinene (5.8%), and delta 3 carena (13.8%); while in P. merkusii are α-pinene (8.2%), ß-pinene (11.5%), limonene (5.2%), α-terpinolene (32.7%), benzenemethanol (4.3%), and trans-pinocarveol (3.5%). All turpentine compounds produced by the two types of pine can be used for various pharmaceutical, cosmetic, and pesticide industries.

Geographical and Climatic Variation of <em>Pinus oocarpa</em> Resin in Southern Mexico Provenances

“…The primary components (rosin and turpentine), quality and genetic gain of resin yield of P. merkusii Jungh. et de Vriese were different among provenances [8,19,20], which highlights the importance of the precedence study for the improvement of resin species such as P. oocarpa.…”

“…and P. merkusii, P. silvestris L. and P. peuce Griseb. [19,[24][25][26]. For Mexican pine species and in particular for P. oocarpa, the relationship between resin characteristics with geographic and climatic variables has not been studied.…”

Characterization of Larix decidua Mill. (Pinaceae) oleoresin’s essential oils composition using GC-MS

“…Similar EO yield was found in the literature for oleoresins from Larix sp. (15-20%) (Weissmann and Reck, 1987), Pinus merkusii (19.6-13.6%) (Sukarno et al, 2015), Pinus roxburghii (16% w/w) (Ayub et al, 2022), Pinus patula (14.55%) and Pinus oocarpa (14.40%) (Sarria-Villa et al, 2021), and Pistacia atlantica L. (10% w/w) (Mohtashami et al, 2023). Oleoresins BU1 and BU3 were obtained in early (May) and late (September) summer (Table 1), respectively, and according to Karimian et al (2020), EO yield (w/ w) from Ferula asa-foetida oleo-gum-resin was higher in July (9.1 ± 1.53%) and lower in October (7.4 ± 0.85%).…”

“…The altitude in these areas varies between 600 and 3900 m, and the precise site of collection and the altitude should be known for a better understanding of the obtained results. The influence of altitude on the oleoresin and EO were investigated by Sukarno et al (2015), who described a positive correlation between the essential oil yield and elevation. Environmental influences need further investigation for Larix decidua oleoresin and EO yield and their bioactive constituents.…”

Resin-Tapping Production in Pinus pinaster Ait. Stands in Galicia (NW Spain): Effects of Location, Number of Faces, Wound Width and Production Year

“…Nevertheless, calculated crown height was similar in both stands, yielding similar resin production when two faces were opened, according to previous findings. According to some researchers, Pinus pinaster displays a large amount of intraspecific genetic variability [51] as well as a high degree of intrapopulational genetic variation [52], giving rise to large differences in resin yields within the same population [24,49,53], with pines of the same genetic material producing up to four times more resin depending on the environmental conditions in the growing area [54]. In a microtapping trial conducted with different populations of Pinus pinaster, significant differences among sites and among populations in inland Galician plots were observed [24].…”
