Hippophae rhamnoides L. (Elaeagnaceae; commonly known as “sea buckthorn” and “vitamin tree”), is a spiny deciduous shrub whose fruit is used in foods and traditional medicines. The H. rhamnoides fruit (berry) is rich in vitamin C, with a level exceeding that found in lemons and oranges. H. rhamnoides berries are usually washed and pressed to create pomace and juice. Today, the powder of the aqueous extract of H. rhamnoides berries are sold as a functional food in many countries. As part of our o...

Garlic (Allium sativum L.) is utilized worldwide for culinary and medicinal use and has diverse health benefits. As part of our ongoing research to identify bioactive components from natural resources, phytochemical analysis of the methanolic extract of garlic led to the isolation and characterization of six compounds: Three eugenol diglycosides (1–3) and three β-carboline alkaloids (4–6). In particular, the absolute configurations of β-carboline alkaloids (5 and 6) were established by gauge-inc...

Withania somnifera (L.) Dunal (Solanaceae), known as Indian ginseng or ashwagandha, has been used in Indian Ayurveda for the treatment of a variety of disorders, such as diabetes and reproductive and nervous system disorders. It is particularly used as a general health tonic, analgesic, and sedative. As part of continuing projects to discover unique bioactive natural products from medicinal plants, phytochemical investigation of the roots of W. somnifera combined with a liquid chromatography–mas...

To discover new pharmacologically active natural products, here, we performed the phytochemical analysis of a Korean medicinal plant. Euonymus alatus (Thunb.) Sieb. is a traditional medicinal plant that has been used as a remedy for various diseases in Asian countries. In particular, the cork cambium on the twigs of E. alatus has been used to treat dysmenorrhea, tumors, diabetes, and wound. Phytochemical analysis of the methanolic extract of E. alatus twigs led to the isolation of a sterol, whic...

Pinus eldarica (Pinaceae), an evergreen plant, is distributed across the warm and dry climates of western Asia, including Asia Minor, the Middle East, and land surrounding the Caspian Sea. Essential oils (EOs) from different aerial parts of this tree have been used in traditional medicine. We aimed to investigate the chemical profile and antimicrobial activity of the EO from P. eldarica grown in northwestern Iran. EO from the needles, bark, and pollen were extracted with boiling water using a Cl...

AbstractAs part of our systematic study on Korean toxic mushrooms, bioactivity-guided fractionation of the MeOH extract of Amanita spissacea (Amanitaceae) fruiting bodies and chemical investigation of its cytotoxic fractions led to the isolation of (9E)-8-oxo-9-octadecenoic acid (1), (10E)-9-oxo-10-octadecenoic acid (2), (9E)-8-oxo-9-octadecenoate methyl ester (3), (9Z)-9-octadecenoate-(2'S)-2',3'-dihydroxypropyl ester (4), (9Z)-9-octadecenoic acid (5), and palmitic acid (6). The structures of t...

: LC/MS-based phytochemical analysis of an EtOH extract of the roots of rice (Oryza sativa; Gramineae), which takes a crucial role in the stable crop population in Asia, resulted in the isolation of a new lignan, oryzativol C (1), as a minor component. The chemical structure of compound 1 was unambiguously confirmed using spectroscopic evidence (including 1D- and 2D-NMR data), HR-ESI-MS, and CD data analysis. Considering the traditional medicinal efficacy of O. sativa and its importance as a foo...
