Compounds

Conditions

Leucas zeylanica exhibits significant anti-inflammatory activity through its isolated diterpenoids. Specifically, the plant helps treat nitric oxide (NO) production in RAW264.7 macrophages. It also works to treat the release of the pro-inflammatory cytokine IL-6 in a dose-dependent manner. Furthermore, the plant's active compounds treat the expression of inducible nitric oxide synthase (iNOS). Finally, Leucas zeylanica effectively treats the expression of cyclooxygenase-2 (COX-2) to suppress inflammatory responses.

Preparations

Leucas zeylanica is prepared as lipophilic extracts to investigate its ability to inhibit key enzymes such as 5-lipoxygenase, mPGES-1, and xanthine oxidase. These lipophilic preparations, including dichloromethane and n-hexane extracts, demonstrate significant anti-inflammatory and anti-gout activities. Additionally, Leucas zeylanica is prepared as aqueous extracts (1 mg/ml) to evaluate its potential for skin protection. These aqueous preparations have shown high UV absorbance and sun protection factor values, making them candidates for broad-spectrum sunscreens. Through these different preparation methods, the plant's medicinal and photoprotective properties are scientifically validated.
