        On the analysis of triacylglycerol (TG) from the kernels of Acanthopanax sessiliflorus by reversed phase-HPLC, it was separated into three main fractions of PN 44, 46 and 48, according to partition number (PN). On the contrary, it could be clearly classified into seven fractions of SMM, MMM, SMD, MMD, SDD, MDD and MDT by silver ion-HPLC by the number of double bond in the acyl chains of TG species. But resolution of so-called critical pairs of TG molecular species such as molecular pairs of PeLL [C18:1Ω12/(C18:2Ω6)2] and OLL [C18:1Ω9/(C18:2Ω6)2] and OOL [(C18:1Ω9)2/C18:2Ω6], and PePeL [(C18:2Ω12)2/C18:1Ω6] was not achieved (Pe; petroselinic acid, L; linoleic acid, O; oleic acid). On the other hand, TG extracted from Aralia continentalis kernels were also fractionated into seven groups of SSM, SMM, MMM, SMD, MMD, SDD and MDD (S; saturated acid, M; monoenoic acid, D; dienoic acid) by silver ion-HPLC, although it's were classified into three groups of PN 44, 46 and 48 by reversed phase-HPLC. The fractions of SMM, MMM, MMD and MDD were divided into two subfractions, respectively; the fractions of SMM, MMM, MMD and MDD were resolved into the subfraction of PPe/Pe and POO (critical pairs from each other), that of Pe/Pe/Pe and OOO, that of Pe/Pe/L and OOL, and that of Pe/L/L and OLL.

        Fatty acid compositions of the seed oils of P. schinseng, A. continentalis and A. sessiliflorus, were analyzed by gas chromatography (GC) equipped with a capillary column. A large unusual peak was observed just before the peak corresponding to oleic acid (cis-9-C18:1). This unknown fatty acid was isolated by silver ion chromatography and then derivatized into the picolinyl ester. The mass spectrum of the picolinyl ester showed molecular ion at m/z=373 with other diagnostic ions such as m/z=178, 218, 232, 246, 274, 288, 302 and 344. Characteristic absorption peaks at 720 cm-1, 1640 cm-1 and 3010 cm-1 in IR spectrum indicated the presence of cis-configurational double bond in the molecule. The 1H-NMR spectrum of this acid gave two quintets centered at δ1.638 (2H, C-3) and δ1.377 (2H, C-4), and two multiplets centered at δ2.022~2.047 (2H, C-5) and δ2.000~2.022 (2H, C-8), and multiplet signals of olefinic protons centered at δ5.3015~5.3426 (C-6, J=9.5 Hz) and δ 5.3465~5.3877 (C-7, J=9.5 Hz). The 13C-NMR spectrum showed 18 carbon resonance signals including an overlapped signal at δ29.7002 for C-12 and δ29.6520 for C-13 (or they can be reversed), and other highly resolved signals at δ33.950, δ24.558, δ26.773 and δ27.205 due to C-2, C-3, C-5 and C-8 of a δ6-octadecenoic acid, respectively. From analysis results this unknown fatty acid could be identified as cis-6-octadecenoic acid. The seed oils of P. schinseng and A. sessiliflorus contained petroselinic acid (59.7%, 56.0%), oleic acid (18.3%, 6.1%) and linoleic acid (16.2%, 30.4%) with small amount of palmitic acid (3.0%, 3.1%) while the seed oil of A. continentalis comprised mainly oleic acid (30.2%), petroselinic acid (29.0%), linoleic acid (24.1%) and palmitic acid (13.1%).

        Purpose – In this study, previous CSR researches was reviewed to help understand the CSR effects, and offer suggestions for future research directions. Research design, data, and methodology – To achieve the purpose of this study, previous CSR effects related researches were reviewed based on stakeholder perspectives. Results - After reviewing, some limitations were found. First, most of the CSR related studies in the management area have focused on CSR effects on individual stakeholders such as the shareholder, the employee, and the consumer. Second, it was difficult to find studies on the management aspect of CSR from both an effective and efficient perspective. Conclusions - To overcome these limitations of previous studies, several studies need to be conducted in the future. First, CSR research must be expanded into B-to-B businesses. Few studies try to figure out the effect of CSR on B-to-B businesses but only suggest the effect of CSR on B-to-B business conceptually. Therefore, empirical study needs to be conducted about CSR to show business performance in the B-to-B market. Second, the process of CSR must be developed on how to improve CSRs’ effectiveness and efficiency. Finally, a relationship between a company and individual stakeholders needs to be revised using stakeholders’ multiple identities.
