“…Massonianoside B has been reported to have antioxidant properties [20], hence their presence in Pinus trees may affect the antioxidant capacity in this species. This is demonstrated by studies in which massonianoside B was separated and purified from the ethyl acetate fraction of P. densiflora extract and was shown to have the strongest antioxidant capacity among all constituents analyzed [31,32]. Therefore, it can be concluded that massonianoside B is a naturally occurring compound in Pinus species and contributes to the biological activity of those species, particularly antioxidant activity.…”

Pinus species are native to the Northern Hemisphere and some parts of the tropics to temperate regions in the Southern Hemisphere. They were used as food and medicine in prehistoric times. Massonianoside B is a compound found in pine trees and possesses antioxidant activity. In order to determine the presence and content of this compound in Pinus species, three different parts (needles, branches, and bark) of three Pinus species were extracted and investigated. High-performance liquid chromatography with a gradient elution system along with a reverse-phase INNO column with photodiode array detector was employed. Results showed that the branches of the three Pinus species had higher massonianoside B content (5.502 to 9.751 mg/g DW) than either the needles or bark. Furthermore, among the three species, P. rigida × P. taeda had the highest concentration of total massonianoside B (11.557 mg/g DW). These findings thus provide evidence of biological activity in Pinus species and establish a foundation for further research.

Wood has different properties depending on the species or growth area. Therefore, in order to use wood efficiently, it is necessary to have a proper understanding of the characteristics of wood depending on the species and the appropriate use for them. In particular, in order to effectively use more than 1,000 species of woody plants in South Korea as wood, it is necessary to evaluate the characteristics of various Korean domestic woods and make a database of them. In this study, the anatomical properties (length and width of tracheid, cell wall thickness), physical properties (specific gravity and shrinkage), mechanical properties (bending strength, compressive strength, tensile strength, shear strength, hardness), and chemical composition (ash, extract, lignin, total sugar content) of Korean red pine which was grown in Pyeongchang-gun, Gangwon-do, South Korea were evaluated.

“…The genus Pinus has an important ecological role in providing habitats for wildlife. Furthermore, its extracts exhibit antimicrobial, antidiabetic, and anti-inflammatory activities [13][14][15][16]. It accounted for approximately 36% of Korea's medium-density fiberboard raw materials in 2008 [17].…”

This study proposes the use of genetic analysis as a complementary method for species identification in the genus Pinus, particularly in cases where anatomical identification is challenging. Pinus species were grouped based on anatomical similarities, and the efficacy of using ycf1b, which is the most variable for Pinus species identification, and rbcL, which is a suggested DNA barcode for land plants, was evaluated within each group. Sequences for each species were obtained from the National Center for Biotechnology Information database and were used to perform phylogenetic analysis. Among the species in Group 1 (P. echinata, P. elliottii, P. ponderosa, P. radiata, P. rigida, P. taeda, and P. virginiana), rbcL was only effective in identifying P. radiata and P. ponderosa, while ycf1b classified five species. An additional DNA barcode, trnH-psbA, was needed to identify P. radiata and P. taeda. In Group 2 (P. densiflora, P. sylvestris, and P. thunbergii), most species were identified using both rbcL and ycf1b, with the exception of possible hybrids of P. densiflora and P. sylvestris. In Group 3 (P. koraiensis and P. strobus), two species were identified using rbcL and ycf1b. Combining genetic species identification with anatomical identification can accurately identify species of the genus Pinus.
