Tsugaric acid A 能够显著抑制超氧阴离子的形成，还可以保护人类角质形成细胞，使其免受紫外线 B 诱导的损害。

Tsugaric acid A can significantly inhibit superoxide anion formation in fMLP/CB-stimulated rat neutrophils, it is also able to protect human keratinocytes against damage induced by ultraviolet B (UV B) light, indicates that tsugaric acid A can protect keratinocytes from photodamage.

Twelve compounds, including ergosta-7,22-dien-3beta-ol (1), ergosta-7,22-dien-3beta-yl palmitate (2), ergosta-7,22-dien-3-one (3), ergosta-7,22-dien-2beta,3alpha,9alpha-triol (4), 5alpha,8alpha-epidioxyergosta-6,22-dien-3beta-ol (5), ganoderal A (6), ganoderal B (7), ganoderic aldehyde A (8), Tsugaric acid A (9), 3-oxo-5alpha-lanosta-8,24-dien-21-oic acid (10), 3alpha-acetoxy-5alpha-lanosta-8,24-dien-21-oic acid ester beta-d-glucoside (11), and tsugaric acid B (12), were assessed in vitro by determining their inhibitory effects on the chemical mediators released from mast cells, neutrophils, and macrophages.
