ABSTRACT

Objective::To determine the chloroplast genomes of Liriope spicata var. prolifera, Ophiopogon japonicus in Sichuan and Zhejiang, analyze their sequence characteristics and complete the screening of specific DNA barcodes. Method::The chloroplast genomes of L. spicata var. prolifera, O. japonicus in Sichuan and Zhejiang were sequenced, spliced and annotated through high-throughtput sequencing technology, and the structural characteristics and phylogenetic relationships of chloroplast genomes were analyzed by bioinformatics. Result::The total length of chloroplast genome of L. spicata var. prolifera was 155 998 bp, the total content of guanine and cytosine (GC) was 37.7%, and 85 protein-coding genes, 37 transfer RNA (tRNA) genes and 8 ribosomal RNA (rRNA) genes were successfully annotated, a total of 274 simple sequence repeats (SSRs) were detected, the number of codons encoding leucine was the most, while the number of codons encoding tryptophan was the least. The total length of chloroplast genome of O. japonicus in Sichuan province was 156 078 bp, the total content of GC was 37.8%, and 85 protein-coding genes, 37 tRNA genes and 8 rRNA genes were successfully annotated, a total of 265 SSRs were detected, the number of codons encoding leucine was the most, while the number of codons encoding tryptophan was the least. The total length of chloroplast genome of O. japonicus in Zhejiang province was 156 207 bp, the total content of GC was 37.7%, and 85 protein-coding genes, 37 tRNA genes and 8 rRNA genes were successfully annotated, a total of 274 SSRs were detected with the highest number of codons encoding leucine and the lowest number of codons encoding tryptophan. Conclusion::The phylogenetic trees show that compared with O. japonicus in Sichuan province, L. spicata var. prolifera is more closely related to O. japonicus in Zhejiang province. The variation of non-coding regions of L. spicata var. prolifera, O. japonicus in Zhejiang and Sichuan is greater than that in the coding region. The entire chloroplast genome can be used as a super barcode for identifying species of Ophiopogon and Liriope.

ABSTRACT

The study identified the main morphological index of the seedlings classification including seedling age,the root width and number of newborn buds and coarse roots, according to the local agricultural production techniques and assessment of Liriope spicata's growth and development condition. After carrying on K cluster analysis of the morphological, we separated the seedlings into two levels. The first level (Ⅰ): the new talent with the root width exceeding two point five millimeters, the new born buds exceeding three, and with the coarse root exceeding one. The second level (Ⅱ): the old talent with the root width below one millimeters, the newborn buds below two and without coarse root. The study surveyed the plants' growth index dynamics, as well as the yield and quality of the tuberous root. The experimental results suggested that the growth condition of seedling Ⅰwas better, the yield of earthnut higher, the quality of earthnut more excellent. The study lied the foundation of L. spicata's grading standards and standardized production.

ABSTRACT

Objective:To perform textual researches on name, origin and distribution of Maidong to clarify the medicinal varieties and history recorded in ancient literatures and provide evidence for clinical use. Methods:Ancient herbal works were performed textual research, and the resource investigation and modern data were analyzed. Results:According to the ancient herbal records and modern researches, Maidong had lots of alias, while only Maimendong and Maidong were used as the medicine common names. According to the records of main origin, original plant morphological and medicinal characteristics of Maimendong, it was preliminarily concluded that Maidong recorded in the ancient herbal records was mainly produced in Jiande of Zhejiang province, Mianyang of Sichuan prov-ince, Xiangyang of Hubei province and the surrounding areas. The chemical compositions and pharmacological activities of Maidong and Shanmaidong were similar;therefore, they both could be used as the medicines. Conclusion:In the light of the ancient and mod-ern medicinal customs, modern chemistry and pharmacology researches and clinical practice of TCM, it deserves further discussion on whether Maidong and Shanmaidong can be used as multi source varieties of traditional Chinese medicines just like Polygonaceae plants palmatum L. , Rheum tanguticum Maxim, ex Balf. and Rheum officinale Baill. , and Ranunculaceae plants Coptis chinensis Franch. , Coptis deltoidea C. Y. Cheng et Hsiao and Coptisteeta Wall.

ABSTRACT

We found previously that water soluble extract of Liriope spicata Lour (SanMaiDong) possesses cardioprotective action. The paper reported that effects of total aminoacid ex- traded from Liriope spicata Lour (Tal) on experimental myocardial ischemia in rats. The results indicate that Tal (5 mg?kg-1 ,ip) obviously antagonized ischemic ECG changes induced by pituitrin in rats. In myocardial ischemic rats caused by isoprenaline (8 mg?kg-1) Tal 15 mg? kg-1ip significantly reduced ST and decreased CPK release and lowered the content of MDA. In a myocardial ischemic mode) induced by ligat-ing the left anterior descending coronary artery in rats, Tal 15 mg?kg-1ip remarkably decreased plasma CPK and FFA levels and was found todiminish the infarct size. The ratio of its infarct size (5. 80%) is similar to that of propranolol (5. 41%),but apparently smaller than that of ligated group (18.55%). The results suggest that Tal can protect ischemic myocardium and this action may relate to the prevention of my-ocardial lipid peroxication and improvement of myocardial metabolism.
