Chemical examination of plant constituents responsible for oviposition by a Magnoliaceae-feeding butterfly, Graphium doson, was conducted using its major host plant, Michelia compressa. A methanol extract prepared from young leaves of the plant elicited a strong oviposition response from females. The methanolic extract was then separated by solvent partition into three fractions: CHCl3, i-BuOH, and aqueous fractions. Active substance(s) resided in both i-BuOH- and water-soluble fractions. Bioassay-guided further fractionation of the water-soluble substances by means of various chromatographic techniques led to the isolation of an oviposition stimulant. The stimulant was identified as D-(+)-pinitol on the basis of 13C NMR spectra and physicochemical properties. D-(+)-Pinitol singly exhibited a moderate oviposition-stimulatory activity at a dose of 150 μg/cm2. This compound was present also in another host plant, Magnolia grandiflora, in a sufficient amount to induce oviposition behavior of G. doson females. Certain cyclitols including D-(+)-pinitol have been reported to be involved in stimulation of oviposition by some Aristolochiaceae- and Rutaceae-feeding papilionid butterflies. A possible pathway of phytochemical-mediated host shifts in the Papilionidae, in which certain cyclitols could enact important mediators, is discussed in relation to the evolution of cyclitol biosynthesis in plants.

Psoriasis is an autoregulated immune and inflammation-based skin disease affecting approximately 3-4% of the worldwide population. Pinitol, conservatively used in ayurvedic medicine, has been shown to disclose an antiinflammatory effect, hold back the T-helper cells, and postpone cardiovascular diseases. In the present study we aimed to reveal the effect of D-pinitol on imiquimod (IMQ)-induced psoriasis-like skin inflammation in a mouse model via the nuclear factor-κB (NF-κB) pathway genes. In the current study, we found that D-pinitol ameliorated the skin abrasion and abridged epithelial thickness, inflammation numbers, and collagen-occupied regions in IMQ-induced psoriasis-like mice. The same results (epithelial thickness, inflammation numbers, and collagen-occupied regions) we achieved in dorsal skin regions. In addition, D-pinitol modified the lipid profile and antioxidant enzyme levels, which means that the IMQ-induced group showed elevated malondialdehyde when compared to D-pinitol. Downregulated expression of glutathione, superoxide dismutase, and catalase in the IMQ-induced group was incomparable with D-pinitol, control, and standard group. Additionally, inflammatory and NF-kB pathway gene levels in the psoriatic mouse skin, which includes tumor necrosis factor-α, interleukin [IL]-6, IL-17A, IL-23,TRAF3, NIK, IKKα, and RelB, were dramatically increased or decreased by treatment with D-pinitol. Histological and morphometric studies disclose the efficiency of D-pinitol. Finally, we found that D-pinitol reserved the TRAF3, NIK, IKKα, and RelB in the psoriatic skin, signifying that it restrains the commencement of NF-κB signaling pathways. The present results suggest that D-pinitol could prove to have tremendous preventive potential against the treatment and prevention of inflammatory disease.

d-pinitol is the most commonly accumulated sugar alcohol in the Leguminosae family and has been observed to increase significantly in response to abiotic stress. While previous studies have identified genes involved in d-pinitol synthesis, no study has investigated transcript expression in planta. The present study quantified the expression of several genes involved in d-pinitol synthesis in different plant tissues and investigated the accumulation of d-pinitol, myo-inositol and other metabolites in response to a progressive soil drought in soybean (Glycine max). Expression of myo-inositol 1-phosphate synthase (INPS), the gene responsible for the conversion of glucose-6-phosphate to myo-inositol-1-phosphate, was significantly up regulated in response to a water deficit for the first two sampling weeks. Expression of myo-inositol O-methyl transferase (IMT1), the gene responsible for the conversion of myo-inositol into d-ononitol was only up regulated in stems at sampling week 3. Assessment of metabolites showed significant changes in their concentration in leaves and stems. d-Pinitol concentration was significantly higher in all organs sampled from water deficit plants for all three sampling weeks. In contrast, myo-inositol, had significantly lower concentrations in leaf samples despite up regulation of INPS suggesting the transcriptionally regulated flux of carbon through the myo-inositol pool is important during water deficit.

D-pinitol (3-O-Methyl-D-chiro-inositol) is a natural compound presented in several plants, like Pinaceae and Leguminosae plants. D-pinitol exerts hypoglycemic activity and protective effects in the cardiovascular system.
