Filipendula ulmaria (L.) Maxim. (Meadowsweet) is known in traditional medicine as anti-inflammatory, wound-healing,astringent and antibacterial remedy. However recent studies show that it also has neurotropic activity. In Russia meadowsweet flowers are used as crude herbal drugs (temporary pharmacopoeial monograph 42-1777-87), also leafs and herb are used in the traditional medicine. Objective of the study was to carry out comparative investigation of composition and content of major biologically active compounds (BAC) in Filipendula ulmaria herb, flowers and leafs by thin-layer chromatography, differential spectrophotometry with aluminum chloride reagent (total flavonoids in terms of rutoside), gravimetry (total extractives, extracted by water), permanganatometric titration (total tannins in terms of tannin). Rutoside, tannin, gallic acid and salicylic acid were identified in Filipendula ulmaria herb, flowers and leafs by TLC. Also we analyzed content of substances extracted by water, flavonoids and tannins. Total extractives, extracted by water in F. ulmaria herb is 13.12±0.10%, in leafs – 13.98±0.37%, in flowers – 18.09±0.17%. Total tannins in F. ulmaria herb is 11.87±0.47%, in leafs – 12.06±0.18%, in flowers – 12.26±0.29%. Total flavonoids in F. ulmaria herb 4.34±0.17%, in leafs – 6.98±0.23%, in flowers – 11.75±0.57%. The obtained data will be used for development of a pharmacopoeial monograph project "Filipendula ulmaria (L.) Maxim., herba" for inclusion in the State Pharmacopoeia of the Russian Federation.

Abstract Unorganized callus and leaf/root-differentiating callus cultures of Pimpinella major have been established in liquid nutrient medium. Their capacity to accumulate rare phenylpropanoids such as epoxy-pseudoisoeugenol tiglate, epoxy-anol tiglate and anol tiglate was compared with that of seedlings and whole plants. The unorganized callus cultures were not able to accumulate any phenylpropanoids. In comparison, the leaf/root-differentiating callus culture promoted the accumulation of epoxy-pseudoisoeugenol tiglate (up to 90 mg/100 g fr.wt.) but not that of anol-derivatives. The accumulated amount of EPT in PMD-SH was comparable with that in plant seedlings.
