- Abstract:
- ... Nineteen ent-kaurane diterpenes were isolated and identified from the barks of Gochnatia decora (Kurz) A. L. Cabrera (Compositae), which has been used as an ethnic medicine for treating cough, asthma and wounds in southwestern China. Among them, six compounds are previously undescribed ent-kaurenoic acids, and a known compound, 7β,15β-dihydroxy-ent-kaur-16-en-19-oic acid, was obtained for the firs ...

- Abstract:
- ... Lavender essential oils (EOs) of higher quality are produced by a few Lavandula angustifolia cultivars and mainly used in the perfume industry. Undesirable compounds such as camphor and borneol are also synthesized by lavender leading to a depreciated EO. Here, we report the cloning of bornyl diphosphate synthase of lavender (LaBPPS), an enzyme that catalyzes the production of bornyl diphosphate ( ...

- Abstract:
- ... The cultivated potato Solanum tuberosum is unrivalled among crop plants for its wild relatives, which potentially represent an important source of genetic diversity to improve the nutritional value of potato varieties and understand metabolism regulation. The main aim of this research was to profile human health-related metabolites in a number of clones from 13 Solanum species. Results from HPLC-D ...

- Abstract:
- ... Phytochemical investigations on n-butanol extract of Cephalaria balansae Raus. (Caprifoliaceae) led to the isolation of four previously undescribed triterpenoid saponins based on hederagenin type aglycone, namely, balansoides A-D, along with ten known compounds. Their structures were proposed based on 1D and 2D NMR spectroscopic data, HRESIMS analysis and chemical evidence as 3-O-α-L-rhamnopyranos ...

- Abstract:
- ... Stevia rebaudiana (Bertoni) Bertoni is a plant that biosynthesizes a group of natural sweeteners that are up to approximately 400 times sweeter than sucrose. The sweetening components of S. rebaudiana are steviol glycosides (SGs) that partially share their biosynthesis pathway with gibberellins (GAs). However, the molecular mechanisms through which SGs levels can be improved have not been studied. ...

- Abstract:

All seven compounds displayed MS-MS-fragmentation common for strigolactones and particularly the presence of a fragment of m/z 97 Da, which may indicate the presence of the so-called D-ring, suggests they are strigolactones. The levels of all these putative strigolac ...

Until the mid-60s, only the Mazatecs, an indigenous group from Oaxaca, Mexico, used Salvia Divinorum (S. divinorum) due to its hallucinogen properties.Later it was found that the hallucinogen effects of this plant were caused by the presence of a neoclerodane diterpene Salvinorin A (salvinorin A), which is a highly selective agonist of kappa-opioid receptor (KOR) that cause more intense hallucinat ...

- Abstract:
- ... S-limonene synthase is a model monoterpene synthase that cyclizes geranyl pyrophosphate (GPP) to form S-limonene. It is a relatively specific enzyme as the majority of its products are composed of limonene. In this study, we converted it to pinene or phellandrene synthases after introducing N345A/L423A/S454A or N345I mutations. Further studies on N345 suggest the polarity of this residue plays a c ...

Eucalyptus grandis and Eucalyptus globulus are among the most widely cultivated trees, differing in lignin composition and plantation areas, as E. grandis is mostly cultivated in tropical regions while E. globulus is preferred in temperate areas. As temperature is a key modulator in plant metabolism, a large-scale proteome analysis was carried out to investigate changes in the antioxidant system a ...
