Usage

Description

An alkaloid from Mahonia nepalensis DC. (Syn. Berberis nepalensis Spreng), this base is optically inactive and forms garnet-red crystals which decompose on heat_x0002_ing. The base contains 3.5 mole of H20 and still retains 1 mole even or prolonged drying at 100°C in vacuo. The salts are said to be orange or yellow.

Uses

Jatrorrhizine, is an alkaloid extract from the Berberidaceae family of plants displaying antioxidant activity.

Bamahongting derived from cortex phellodendri salt roasted product as well as separation and preparation method and application thereof

The invention discloses Bamahongting derived from a cortex phellodendri salt roasted product. The molecular formula is C20H20NO4, Bamahongting is named, and the chemical structural formula is shown inthe specification. The separation and preparation method of the compound comprises the following steps of (1) precisely weighing a palmatine reference substance, putting the palmatine reference substance into an evaporating dish, baking in a baking oven, taking out, cooling, adding chromatographic grade acetonitrile, and filtering by a microfiltration membrane to obtain a baked palmatine sample solution, (2) separating the baked palmatine sample solution by using a preparative liquid phase, collecting eluent of a target chromatographic peak, and purifying by using a sephadex column, and carrying out nitrogen blowing and freeze drying on the purified eluent to obtain pink powder, namely the Bamahongting crystal prepared by separation. The Bamahongting provided by the invention is a new compound discovered in cortex phellodendri salt roasted product decoction pieces for the first time, the separation and preparation method has the characteristics of convenience in operation, high preparation efficiency and the like, high-purity separation and preparation of a large amount of Bamahongting monomers can be realized, and the Bamahongting compound has a very good anti-inflammatory effecton RAW264.7 cells stimulated by LPS.
