Identification
Morphology
Ligustrum obtusifolium is a versatile shrub known for its sturdy and self-supporting structure. This plant typically maintains a controlled presence in the landscape, generally reaching a height between 2 and 3 meters. While most specimens stay within this range, some instances can reach a maximum height of 3 meters. Occasionally, certain variations may even push slightly higher, reaching up to 3.1 meters in ideal conditions. Ultimately, its reliable growth form makes it an excellent choice for various garden settings.

Preparations
Ligustrum obtusifolium is prepared as an ethanol extract using its twigs and leaves to facilitate chemical analysis. This extraction process allowed researchers to isolate seven specific compounds through the use of polystyrene resin RA and silica gel column chromatography. The identified constituents included luteolin, luteolin-4'-O-beta-D-glucopyranoside, (+)-pinoresinol, (+)-pinoresinol-4'-O-beta-D-glucopyranoside, (+)-medioresinol, and (-)-olivil. Notably, several of these compounds were isolated from this particular plant species for the very first time. The spectral analysis confirmed the structures of these elements derived from the ethanol-based preparation.
