Scientific literature: Very Sparse (2 studies) · ★☆☆☆☆
Ligustrum lucidum is a versatile botanical species whose medicinal potential is primarily derived from its dried fruit, often prepared as aqueous extracts known as Ligustri Lucidi Fructus. The plant is chemically rich in bioactive compounds, including oleanolic acid, ursolic acid, flavonoids, and 19alpha-hydroxyl acetylursolic acid. These constituents provide significant therapeutic activities, such as antioxidant and antiosteoporotic effects, as well as serving as 11B-HSD and 5-alpha-reductase inhibitors. Research indicates that these extracts may play a role in addressing various health conditions, including oxidative injury and certain concerns related to the breast, lung, and pancreas. Consequently, the fruit remains a subject of intense study for its complex pharmacological profile.

Identification
Morphology
Ligustrum lucidum is a self-supporting plant that takes on a distinct tree growth form. This species exhibits a versatile size range, with some specimens reaching a minimum height of only 3 meters. However, larger individuals can grow significantly larger, with heights typically starting around 15 meters. In certain environments, the plant may even exceed these dimensions to reach a height of 16.5 meters. This impressive stature allows the tree to establish a commanding presence within its ecosystem.

Biological Activities
Ligustrum lucidum stands out as a versatile medicinal plant with significant therapeutic potential. Research identifies it as one of several key species utilized for its antiosteoporotic properties in traditional medicine. Beyond bone health, the plant also exhibits notable antioxidant activity. This protective effect is closely linked to its rich composition of phenolics, flavonoids, and essential trace metals. Consequently, these bioactive components work together to support the plant's overall health-promoting capabilities.
Compounds
Ligustrum lucidum is a medicinal plant characterized by a diverse profile of bioactive secondary metabolites. Research indicates that the fruit contains significant amounts of flavonoids, which contribute to its antioxidant and anti-inflammatory properties. Detailed chemical analyses have identified several key triterpenoids within the plant, including oleanolic acid and ursolic acid. Furthermore, specific compounds such as specnuezhenide are present and can be used to evaluate the overall quality of the crude drug. The complex chemical makeup of the plant is even more nuanced, as evidenced by the presence of specialized derivatives like 19alpha-hydroxyl acetylursolic acid.
Conditions
Ligustrum lucidum provides significant protection against cellular damage induced by arachidonic acid and iron by regulating the AMPK signaling pathway. This medicinal plant also demonstrates inhibitory effects against the parasite Trypanosoma cruzi in vitro. Its high levels of phenolics, flavonoids, and trace metals contribute to potent antioxidant and anti-inflammatory activities. Furthermore, the sun-dried mature fruit of the plant is traditionally utilized for its ability to blacken hair. These diverse pharmacological properties highlight the multifaceted therapeutic potential of the species.
Preparations
Ligustrum lucidum is prepared as aqueous extracts to evaluate its antiproliferative activity on various cancer cell lines. This plant is also prepared as Ligustri Lucidi Fructus, which consists of the sun-dried mature fruit used for both food and medicinal purposes. The species is frequently prepared as dried fruit due to its high medicinal value in traditional practices. Furthermore, Ligustrum lucidum is prepared as an extract to investigate its ability to inhibit hepatitis C virus replicase activity. Finally, the plant is prepared as fruit to facilitate the study of its chemical constituents and their inhibitory effects on xanthine oxidase.
Parts used
Ligustrum lucidum produces a mature fruit known in medicinal contexts as Fructus Ligustri Lucidi. These fruits are characterized by a complex flavor profile that is simultaneously cool, plain, sweet, and bitter. Chemically, the fruit contains various secoiridoid glucosides, including lucidumosides A and B, which contribute to its biological activity. Research indicates that extracts from this part of the plant can protect hepatocytes against oxidative injury by activating the AMPK signaling pathway. Consequently, the fruit serves a dual purpose in traditional practices, functioning as both a food source and a therapeutic agent to tonify the liver and kidneys.
