The silicon regulates microbiome diversity and plant defenses during cold stress in L.

Introduction: With climate change, frequent exposure of bioenergy and food crops, specifically soybean ( L.), to low-temperature episodes is a major obstacle in maintaining sustainable plant growth at early growth stages. Silicon (Si) is a quasi-essential nutrient that can help to improve stress tolerance; however, how Si and a combination of cold stress episodes influence plant growth, plant physiology, and microbiome diversity has yet to be fully discovered.

Plant based radioprotectors as an adjunct to radiotherapy: advantages and limitations.

Radioprotectors are agents that have the potential to act against radiation damage to cells. These are equally invaluable in radiation protection, both in intentional and unintentional radiation exposure. It is however, complex to use a universal radioprotector that could be beneficial in diverse contexts such as in radiotherapy, nuclear accidents, and space travel, as each of these circumstances have unique requirements.

Functional identification of valerena-1,10-diene synthase, a terpene synthase catalyzing a unique chemical cascade in the biosynthesis of biologically active sesquiterpenes in Valeriana officinalis.

Valerian is an herbal preparation from the roots of Valeriana officinalis used as an anxiolytic and sedative and in the treatment of insomnia. The biological activities of valerian are attributed to valerenic acid and its putative biosynthetic precursor valerenadiene, sesquiterpenes, found in V. officinalis roots.

Comparative study of three Plumbago L. species (Plumbaginaceae) by microscopy, UPLC-UV and HPTLC.

This paper presents a comparative study of anatomy of leaves, stems and roots of three species of Plumbago, namely P. auriculata Lam., P.

A new triterpene glycoside from Centella erecta.

A new (2α,3β)-23-sulphonyl-2,3-dihydroxyurs-12-en-28-oic acid O-α-L-rhamnopyranosyl-(1 → 4)-O-β-D-glucopyranosyl-(1 → 6)-O-β-D-glucopyranosyl ester (1) together with eighteen known compounds were isolated from Centella erecta (L.f.) Fern.

Two new triterpene glycosides from Centella asiatica.

Phytochemical investigation of the leaves of Centella asiatica resulted in the isolation and characterization of eight triterpenes and/or saponins [which were characterized as 23- O-acetylmadecassoside (1), asiatic acid (2), madecassic acid (3), asiaticoside C (4), asiaticoside F (5), asiaticoside (6), madecassoside (7), and 23- O-acetylasiaticoside B (8)] together with sitosterol 3-O-beta-glucoside ( 9), stigmasterol 3- O- beta-glucoside (10), and querectin-3- O-beta-D-glucuronide (11). A new ursane-derived saponin (23- O-acetylmadecassoside) and a new oleanane-derived saponin (23- O-acetylasiaticoside B) were found as well. Structure elucidation was done by using spectroscopic techniques (HR-ESI-MS, 1D and 2D NMR), chemical methods, and comparative literature studies.
