Siamfuranones A-C, three novel furanone derivatives from the flowers of and their biological activities.

Three previously undescribed furanone derivatives named siamfuranones A-C (-), together with 11 known compounds (-), were isolated from the flowers of . Their planar structures were determined through analysis of spectrometric and spectroscopic evidence, while electronic circular dichroism (ECD) calculations were used to determine their absolute configurations. In addition, gauge-including atomic orbitals (GIAO) NMR chemical shift calculation, supported by the advanced statistical method DP4 plus, was used to confirm the relative configuration of siamfuranone B ().

Acrotrione B, a Prenylated and Highly Oxidized Xanthenoid with Antibacterial and Anti-proliferative Activities from the Roots of Acronychia pedunculata.

A new prenylated xanthenoid with a highly oxidized core, acrotrione B (1: ), together with six previously reported acetophenones (2:  - 7: ), were isolated from the roots of . The structures of the isolated compounds were elucidated by thorough analysis of their 1D and 2D NMR spectroscopic data. The relative and absolute configurations of acrotrione B were determined by electronic circular dichroism (ECD) calculations.

Enhancement of growth and Cannabinoids content of hemp () using arbuscular mycorrhizal fungi.

This study aimed to investigate the efficiency of arbuscular mycorrhizal fungi (AMF) to promote growth and cannabinoid yield of KKU05. A completely randomized design (CRD) was conducted with six replications for 60 days. Two different species of AMF, PC2-2 and BM-3 g3 were selected as inocula and compared with two non-mycorrhizal controls, one without synthetic fertilizer and one with synthetic NPK fertilizer.

Scalarane Sesterterpenoids with Antibacterial and Anti-Proliferative Activities from the Mushroom .

Seven undescribed scalarane sesterterpenoids, nambiscalaranes B-H (-), together with two known compounds, nambiscalarane () and aurisin A () were isolated from the cultured mycelium of the luminescent mushroom . Their structures were elucidated by thorough analysis of their 1D and 2D NMR spectroscopic data. The absolute configurations of - were determined by electronic circular dichroism (ECD) calculations and optical rotation measurements.

Co-Inoculation of an Endophytic and Arbuscular Mycorrhizal Fungus Improve Growth and Yield of L. under Field Condition.
