Abstract
An extract from the rhizomes of Cassumunar ginger (Zingiber purpureum Roscoe). was found to have significant α-glucosidase inhibitory activity with an IC50 value of 6.3 µg/mL. Two new phenylbutenoids, cassudimin A (1) and cassumunol N (2), and seven known compounds (3-9) were isolated. Their structures and relative configurations of two new compounds were elucidated based on spectra interpretation. Compounds 1-3, 6-9 showed more potent α-glucosidase inhibitory activity than a positive control, acarbose (IC50 = 168.0 µM). Dehydrozingerone (6) exhibited the most potent α-glucosidase inhibition with an IC50 value of 8.3 μM. Compounds 7 and 9 were found in Z. purpureum rhizomes for the first time.

Abstract
Trans(t)-banglene and cis(c)-banglene possess neurotrophin-like activity in rat neurons. However, the molecular mechanisms underlying t-banglene-induced neurotrophic activity in rat and human neurons remain unclear. Here, we performed transcriptome analysis in PC12 cells, a rat adrenal gland pheochromocytoma cell line treated with t-banglene, using comprehensive RNA sequencing. The differentially expressed gene analysis of the sequencing data revealed that the expression of RT1 class I, locus CE1 (RT1-CE1) was upregulated, and that of ATP binding cassette subfamily A member 1 (abca1), myosin light chain 6, and hippocampus abundant transcript 1 was downregulated in t-banglene-treated PC12 cells, with statistically significant differences. We also confirmed the RT1-CE1 upregulation and abca1 downregulation in t-banglene-treated PC12 cells by reverse transcription quantitative real-time polymerase chain reaction. RT1-CEl is a major histocompatibility complex class I (MHCI) protein. ABCAl is a major cholesterol transporter that regulates efflux of intracellular cholesterol and phospholipids. Thus, our results suggest an exciting link between MHCI, cholesterol regulation, and neural development.

Abstract
Indonesian ginger (Zingiber purpureum Rosc.), also known as Bangle, exhibits neurotrophic effects on cultured murine cortical neurons and in the adult mouse brain, but the underlying mechanisms remain unknown. Here, using human fetal neural stem cells (hfNSCs) as a model system for in vitro human neurogenesis, we show that Bangle extracts activate canonical WNT/β-catenin signaling. Bangle extract-treatment of hfNSCs not only promoted neuronal differentiation, but also accelerated neurite outgrowth from immature neurons. Furthermore, Bangle extracts induced expression of neurogenic genes and WNT signaling-target genes, and facilitated the accumulation of β-catenin in nuclei of hfNSC. Interestingly, altered histone modifications were also observed in Bangle-treated hfNSCs. Together, these findings demonstrate that Bangle contributes to hfNSC neurogenesis by WNT pathway and epigenetic regulation.

Abstract
The insecticidal and repellent activities of the essential oil extracted from Zingiber purpureum Roscoe rhizomes were evaluated against Tribolium castaneum (Herbst) and Lasioderma serricorne (L.) adults. During our screening program for agrochemicals from Chinese medicinal herbs and wild plants, the essential oil of Z. purpureum rhizomes was found to possess strong contact toxicity against T. castaneum and L. serricorne adults, with LD50 values of 39.0 and 16.3 µg per adult, respectively, and also showed strong fumigant toxicity against the two grain storage insects with LC50 values of 13.6 and 9.3 mg/liter of air, respectively. The essential oil obtained by hydrodistillation was investigated by gas chromatography-mass spectrometry. The main components of the essential oil were identified to be sabinene (48.1%), terpinen-4-ol (25.1%), and γ-terpinene (6.7%), followed by α-terpinene (4.3%), β-thujene (3.4%), and α-phellandrene (2.7%). Sabinene, terpinen-4-ol, and γ-terpinene were separated and purified by silica gel column chromatography and preparative thin-layer chromatography. Terpinen-4-ol showed the strongest contact toxicity against T. castaneum and L. serricorne (LD50=19.7 and 5.4 µg per adult, respectively) and also the strongest fumigant toxicity against T. castaneum and L. serricorne (LC50=3.7 and 1.3 mg/liter of air, respectively). Otherwise, sabinene and terpinen-4-ol were strongly repellent against T. castaneum as well as the essential oil, while γ-terpinene exhibited weaker repellency against T. castaneum compared with the positive control, DEET (N, N-diethyl-3-methylbenzamide). Moreover, only the essential oil exhibited strong repellency against L. serricorne, the three compounds exhibited weaker repellency against L. serricorne relative to DEET.

Abstract
Two new curcuminoids 1 and 2, and a new phenylbutenoid dimer 3, were isolated from Bangle (Zingiber purpureum). Their structures were determined on the basis of comprehensive spectroscopic data and their biogenetic pathway. Compounds 1 and 2 are the first example of curcumin coupled with phenylbutenoid. Compounds 1 and 2 promoted neurite outgrowth of NGF-mediated PC12 cells at concentrations ranging from 1 to 10 μM. In addition, compound 1 was found to accelerate the prevention of Aβ42 aggregation.
