Whole grass contains 10% enamel, acidolysis produces leucovorin; the main component of volatile oil is terpene, sesquiterpene; resin [the antibacterial component is called stellate resin I, II (Hyperesin I and II)]; another contains vitamin C Carotene, musk scent (leaf contains 2%, flower 0.095%), hypericum, quercetin, quercetin, caffeic acid, chlorogenic acid, small amount of saponin, β-sitosterol. Roots and stems contain furfural, lauric acid and mannitol. After the whole grass is hydrolyzed with dilute NaOH solution, Imanin with antibacterial ability can be extracted. The whole plant also contains Hypericin, which has the highest content of petals (0.245%). Hypericum perforatum: whole grass contains biguanide: hypericin, pseudohypericin, pro-tohypericin; cyclopseudohypericin ), desmethylcyclopseudohypericin, and reported that the pseudohypericin has a carbon number of 30, so it may be a mixture. The content of hypericin is lower in young plants, and the flowering period is higher; the petals are higher, the leaves are lower, and the stem is the lowest. Indophenol compound: emodinan phenol (emodinanthranol). Volatile oil: 0.6%-1.25% (more flowering, about 2.2%), oil containing terpene, 2-methyloctane, n-decane α-syringene, β-syringene, n-octanal, positive Furfural and trace terpene alcohols. Flavonoids: 3.35%-7.4%, mainly hyperoside, hyperin and musk, and also containing ecdysteroids, isoquercetin and quercetin. Flowers contain hyperforin and adhyperforin. The whole grass still contains a small amount of caffeic acid, chlorogenic acid, choline, niacin, β-sitosterol, colorless anthocyanins, carotene, vitamin C and tannin (about 10%). In addition, the azeotrope of the bacteriostatic agent is obtained by azeotroping the dried plant with 0.5% sodium hydroxide solution; it is contained in the bud stage, full bloom stage or young fruit stage of 2-3 years of plant growth. More antibacterial substances. A new antibacterial substance, Hypericin, was isolated from the preparation of acetone extract, novlimanin, which contains most of the less polar phenolphthalein and small flavonoids and bismuthone compounds in the whole plant. (hyperforin) is a bicyclotetraketone compound containing four isopentenyl chains.
