Objects : Sanjoin, the seeds of Zizyphus vulgaris var. spinosus has been used as the most important hypnotic agent in chinese medicine to treat insomnia. This research was performed in order to examine the effect of betulinic acid and sanjoinine-A which are components of Sanjoin. Method : Sleeping time, sleep recordings of EEG, EMG, serum serotonin level, and locomotor activity were measured in rats which received betulinic acid and sanjoinine-A as sleep induction material extracted from Sanjoin. Results : 1) Groups received betulinic acid, sanjoinine-A, and lorazepam showed increased sleep time than control group with saline. 2) Groups with betulinic acid, sanjoinine-A, lorazepam and saline recorded ${\beta}$-wave in sleep recordings of EEG. In EMG, there was no significant difference among all groups. 3) No significant difference in serum serotonin level among all groups was found. 4) In autonomic activity testing, groups of betulinic acid, sanjoinine-A, and lorazepam showed significantly more decreased in activity than saline group. In comparison of groups of betulinic acid and sanjoinine-A with a group of lorazepam, there was no significant difference. Conclusion : These results suggest that betulinic acid and sanjoinine-A have the sedative effect like lorazepam rather than sleep effect.

A hight performance liquid chromatographic methods was developed for the seperation and determination of seven alkaloids in "sanjoin" (the seeds of Zizyphus jujuba Rhamnaceae), a plant with potent sedative activity. A reverse phase system of Lichrosorb RP-Select B column and 0.05 M potassium phosphate buffer (pH = 3.5)-acetonitrile with gradient elution was employed. Two known alkaloids, juzirine and lysicamine, were newly isolated fom "sanjoin"."sanjoin".oin&".ot;.

The objective of this study was to evaluate the sedative activity of four aporphine alkaloids (APA) and nine cyclopeptide alkaloids(CPA), which had been isolated from the seeds (sanjoin) of Zizyphus vulgaris var. spinosus, and the fruits and stem bark of Zizyphus jujuba var. inermis. The assessment of sedative activity was carried out, employing a hexobarbital-induced sleeping time method in mice. When the relative sedative potency of sanjoinine-A(CPA) was given as one unit, those of nuciferine (APA), lysicamine (APA), chlorpromazine (positive control), and sanjoinine -Ahl (an epimer of sanjoinine-A) were 13, 6.5, 5, and 3, respectively. The sedatvie activities of other CPAs were much lower than those of sanjoinine-A and -Ahl, and other APAs were not active. On heat treatment, nuciferine and lysicamine were degraded into some artifacts which exhibited no sedative activity, while sanjoinine-A was converted into sanjoinine-Ahl which showed more potent sedative activity. These results suggested that nuciferine and sanjoinine-A were major sedative components of native sanjoin, and that sanjoinine-A and its epimeric artifact, sanjoinineAhl were the active principles of roasted sanjoin. It provides a scientific basis for heat-processing (roasting) of this Oriental medicine.

This study was carried out to evaluate the putative anxiolytic-1ike effects of the aqueous extracts of Sanjoin-tang (SJIT) and its ingredients using the elevated plus maze (EPM) test in mice. SJIT consists of five herbs, namely, Zizyphi Spinosi Semen (roasted), Glycyrrhizae Radix, Cnidii Rhizoma, Anemarrhenae Rhizoma, and Hoelen. The aqueous extracts of SJIT and each herbal drug were orally administered to ICR mice, 1 hr before evaluating behavioral activity in the EPM test, respectively. Repeated treatments (for 3 days) of the aqueous extract of SJIT (400 mg/kg) significantly increased time-spend in the open arms and arms entries into the open arms in the EPM test. Zizyphi Spinosi Semen (400 mg/kg), an ingredient of SJIT, significantly increased timespent in the open arms and arm entries into the open arms (P < 0.05). However, the other ingredient of SJIT did not show any anxiolytic-like behaviors. In addition, the anxiolytic-like effects of Zizyphi Spinosi Semen were blocked by pindolol (lO mg/kg), a $5-HT_{1A}$ receptor antagonist. These results suggest that Zizyphi Spinosi Semen (roasted) as an ingredient of SJIT plays a crucial anxiolytic role, and it acts via the serotonergic nervous system.

Objectives : The purpose of this systematic review was to investigate the efficacy and safety of Sanjoin-tang (Suanzaoren decoction, SZRD) for insomnia in menopausal syndromes. Method : We searched the following databases: PubMed, Cochrane Library, EMBASE, China National Knowledge Infrastructure (CNKI), Chinese Science and Technique Journals Database (VIP), Wanfang, Research Information Service System (RISS), OASIS, Korean studies Information Service System (KISS), and National Digital Science Library (NDSL) databases. Randomized controlled trials (RCTs) or quasi-RCTs that used SZRD for women in menopause were included. The methodological quality of each RCT was assessed using the risk of bias tool. Results : In total, nine RCTs were finally included. The included RCTs had a high risk of bias across their domains. Three RCTs examined the effects of SZRD compared with western medicine (WM) in insomnia. Three RCTs showed favorable effects of SZRD with insomnia. Infrastructure also showed that SZRD resulted in better clinical WM (RR 1.19, 95% CI 1.07 to 1.32, P=0.001, I²=0%). Four RCTs showed favorable effects of Modified SZRD with insomnia. Infrastructure also showed that Modified SZRD resulted in better clinical WM (RR 1.13, 95% CI 1.04 to 1.23, P=0.004, I²=0%). Among the 4 RCTs, three RCTs showed an equivalent effect on the total Pittsburh Sleep Quality Index (PSQI). The meta-analysis also showed that Modified SZRD had a superior effect on the total of PSQI (total of PSQI : MD -2.55, 95% CI -3.72 to -1.37, P<0.0001, I²=85%). Only 2 trials reported adverse events and none reported severe adverse events. Conclusion : SZRD appears to be safe, but there is insufficient evidence to make a definitive conclusion because only a few studies reported adverse events. Due to the poor methodological quality of the included studies and the small number of trials included, the evidence cannot be reproduced and assessed. Well-designed RCTs with a larger sample size are needed in the future.

Objectives: The coronavirus disease 2019 (COVID-19) has become a global pandemic. Mental sequelae occurring in patients with COVID-19 and the general population are important concerns. In Korea, herbal medicine is used nationwide to respond to this pandemic. It can be prescribed by COVID-19 telemedicine center of Korean medicine (KM). Among some herbal medicines, Gamiguibi-tang is the only herbal medicine prescribed for individuals with mental health, especially for those with insomnia. In this mini-review, the objective of this study was to summarize the evidence of some promising herbal medicines available for treating primary insomnia based on existing clinical and preclinical studies. Methods: A research team was formed for KM clinical practice guidelines for insomnia (version 1.0). Team members were provided with a list of references of relevant herbal medicines for insomnia. To gather evidence from clinical studies with appropriate sample sizes, among the list of references, randomized controlled trials for primary insomnia that included 50 subjects or more per arm and used herbal medicine were included in the final analysis. Moreover, pre-clinical studies examining the mechanism of action of each herbal medicine and studies on herb-drug interactions, were searched and summarized. Results: Four herbal medicines (Ondam-tang, Sanjoin-tang, Guibi-tang, and Hyeolbuchugeo-tang) were reviewed based on existing clinical and preclinical studies. Based on findings of existing studies, some suggestions of herbal medicines for insomnia in the COVID-19 era in Korea were suggested. Conclusions: Data of this study could be used to prepare a future revision of the manual of COVID-19 telemedicine center of KM.
