Source of material

Three kilograms of dry ripe fruit powder of Schisandra sphenanthera Rehd. et Wils was extracted with 95, 90, and 70% methanol-water at room temperature three times (5 d/time) in turn. All filtrates were combined, and the total extract was 9.571 kg by concentrating and recovering solvents. The total extract was dissolved in warm water, extracted with petroleum ether and ethyl acetate in turn, and concentrated under reduced pressure to obtain 1.502 kg of petroleum ether and 1.08 kg of ethyl acetate. MCI decolorized the ethyl acetate fraction, and the eluent was a methanol-water (50:50, 60:40, 70:30, 80:20, 90:10, 100:0) system. After TLC detection, the resulting fractions were divided into six fractions (A–F). The D fraction was eluted by dichloromethane-methanol (99:1, 49:1, 19:1, 9:1, 4:1, 3:1, 1:1) gradient chromatography on the silica gel column. The fractions were detected by TLC and combined to obtain five fractions (D1–D5). The D1 fraction was eluted by a petroleum ether-ethyl acetate system repeatedly to give the target compound (48 mg). The target compound was recrystallized by methanol for two days to acquire a colorless crystal. The system name was 1,2,3,5,13-pentamethoxy-6,7-dimethyl-1,2,3,4,4a,5,6,7,8,13b-decahydrobenzo[3′,4′]cycloocta[1′,2′:4,5]benzo [1,2-d][1,3]dioxole.

Experimental details

The carbon-bound hydrogen atoms were placed in their geometrically idealized positions and constrained to ride on their parent atoms with d(C–H) = 0.93–0.98 Å, Uiso(H) = 1.5 times Ueq(C) and 1.2 times Ueq(O).

Comment

Schisandra chinensis (Turcz.) Baill. is a dry and mature fruit of Schisandra sphenanthera Rehd. et Wils and Schisandra chinensis (Turcz.) in Magnoliaceae. The former is used to be called “Bei Wuweizi”, while the latter is used to be called “Nan Wuweizi” in Chinese [5]. Schisandra chinensis is sour, sweet, and warm in nature; its drug action is fixed in the lung, heart, and kidney, with the curative effects of astringent, supplementing and generating fluid, and tonifying the kidney and comforting the heart [6].

In Guizhou folk medicine, there is a tradition of using Schisandra chinensis as medicine, which is mainly based on “Schisandra chinensis (Turcz.) Baill.” Widely distributed in Guizhou, Schisandra chinensis (Turcz.) Baill. is rich in resources. Studies have shown that Schisandra chinensis contains a variety of chemical constituents. Lignans are its main chemical constituents and main active components. In terms of pharmacological effects, lignans can protect the liver and reduce enzymes, anti-inflammatory, antioxidant, anti–HIV, anti-tumor, and antiviral. In recent years, it has been revealed that lignans and triterpenes of Schisandra chinensis (Turcz.) Baill. also have inhibitory effects on the central nervous system [7], [8], [9]. The research group has successfully isolated various lignans from Schisandra sphenanthera Rehd. et Wils produced in Guizhou. As research on lignans gradually deepens both at home and abroad, it is vital to study and elucidate the structure of lignans.

The target compound is shown in figure, which consists of an eight-membered ring, two benzene rings, five methoxy groups, two methyl groups, and two ether bonds. Bond distances and bond angles in the molecule were within normal ranges [10, 11]. The ether bonds were confirmed by the distance of 1.387(3) Å (C13–O7) and 1.381(3) Å (C12–O6). And the methoxyl groups were confirmed by the distance of 1.375(3) Å (C1–O1), 1.377(3) Å (C2–O2), 1.363(3) Å (C3–O3), 1.369(3) Å (C14–O5) and 1.431(3) Å (C6–O4), respectively [12].
