Identification
Morphology
Sagina japonica is a charming herb characterized by its low-growing and self-supporting structure. This resilient plant maintains a compact presence, typically reaching a maximum height of only 0.2 meters. Depending on its specific environment, the height of an individual specimen can vary significantly. Most instances will measure at least 0.05 meters, though many stay closer to a minimum of 0.125 meters. These growth characteristics make it an ideal choice for groundcover applications.

Preparations
Sagina japonica is prepared as whole plants to facilitate the isolation of specific chemical compounds. Researchers utilized these whole plants to extract two newly identified cyclic peptides, known as sajaponicin C and sajaponicin D. The structural determination of these peptides was achieved through the analysis of spectroscopic data derived from the plant material. Specifically, two-dimensional NMR techniques were employed to map the complex structures of the isolated substances. This preparation method proved essential for the successful discovery of these unique cyclopeptides from the Caryophyllaceae family.
