Metabolomic and chemometric analyses of St. John's wort and related Asian Hypericum species linked to bioactivity.

Ethnopharmacological Relevance: Plants in the genus Hypericum (Hypericaceae), include more than 500 species worldwide, and many are valued for their medicinal properties, and are used as traditional herbal medicines. However, only H. perforatum is officially recognized as herbal drug in several pharmacopoeias, and used as an antidepressant clinically.

Chromosome-level genome assembly of provides insights into the biosynthesis of flavor compounds.

is an economically important spice plant in the ginger family (Zingiberaceae). The dried ripe fruit has been widely used as spice and medicine in Southeast Asia due to its distinct flavor metabolites. However, there is little genomic information available to understand the biosynthesis of its characteristic flavor compounds.

Differences in Leaf Chemistry and Glandular Trichome Density between Wild Southwestern American Hop () and Commercial Hop Cultivars.

The female flowers ("cones") of the hop plant ( L.) produce compounds that contribute to the flavor and other properties of beer. Hop leaves and cones produce many of the same compounds, which also confer agronomic traits such as insect and disease resistance.

UPLC-QTof-MS Metabolomics Reveals Changes in Leaf Primary and Secondary Metabolism of Hop ( L.) Plants under Drought Stress.

The hop ( L.) is an important specialty crop used in beer production. Untargeted UPLC-QTof-MS metabolomics was used to determine metabolite changes in the leaves of hop plants under varying degrees of drought stress.

Gaultheria longibracteolata, an alternative source of wintergreen oil.

Gaultheria longibracteolata (Ericaceae) has been traditionally used by different linguistic groups in Yunnan Province, China, but it has not been well studied. Through our ethnobotanical study in Lüchun County of Yunnan, we found that this species has multiple traditional uses including food, medicine, and worship. The essential oils from the root, stem, and leaf were investigated by both GC-MS and anti-bacterial assays.

Identification of tandem repeat families from long-read sequences of Humulus lupulus.

Hop (Humulus lupulus L.) is known for its use as a bittering agent in beer and has a rich history of cultivation, beginning in Europe and now spanning the globe. There are five wild varieties worldwide, which may have been introgressed with cultivated varieties.

Hop (Humulus lupulus L.) terroir has large effect on a glycosylated green leaf volatile but not on other aroma glycosides.

Genetics and environment both influence the content of hop (Humulus lupulus L.) aroma compounds. The effects of these two factors on aroma glycosides, which can change the aroma profile of beer over time, were examined in a preliminary study.

Metabolic Profiling of Different Parts of Acer truncatum from the Mongolian Plateau Using UPLC-QTOF-MS with Comparative Bioactivity Assays.

Acer truncatum is an important ornamental, edible, and medicinal plant resource in China. Previous phytochemical research has focused on the leaf (AL) due to its long history as a tea for health. Other parts such as the branch (ABr), bark (ABa), fruit (AF), and root (AR) have drawn little attention regarding their metabolites and bioactivities.

[Studies on volatile oils compounds of Acorus macrospadiceus based on GC-MS, an ethnomedicinal and food plant used by local people in southwest China].

Acorus macrospadiceus is a common medicinal and food plant used different ethnic groups in Guizhou and surrounding areas. In this paper, the leaf and rhizome tissues of A. macrospadiceus were hydro-distilled to extract the volatile oils.
