phlomis/二酸化ケイ素

Phlomis umbrosa is a traditional medicinal plant, distributed in the north of China. In the west of Hubei province, its roots were used in the treatment of the rheumatic diseases in Tujia nationality. To study the chemical constituents from the rhizome of Phlomis umbrosa chemical constituents were

OBJECTIVE To study the chemical constituents of Phlomis younghusbandii. METHODS Compounds were isolated from the ethanolic extract by silica gel column chromatography, and their structures were identified by physical and chemical evidences and spectral methods. RESULTS Eight compounds were isolated

Phlomis bruguieri (P. bruguieri) is a large genus in the Lamiaceae family, with a wide variety distributed in Euro-Asia, Central Asia, Iran, and China. Phlomis flowers have been used as herbal tea for gastrointestinal disturbances, protection of liver and cardiovascular systems. The aim of this

A new isobenzofuranone derivative has been isolated from Phlomis betonicoides by using various chromatographic techniques, including silica gel, Sephadex LH-20, MCI-gel resin and RP-HPLC. This compound was determined as 5-(3-hydroxypropyl)-2,2-dimethyl-2H-furo[3,4-h]chromen-7(9H)-one (1) by NMR, MS,

OBJECTIVE To study the chemical constituents in root of Phlomis medicinalis. METHODS The compounds were isolated and repeatedly purified on macroporous resin, silica gel column chromatography, TLC and Prep-HPLC and the structures were elucidated by physico-chemical properties and NMR
