“…Bamboo grass possessing developed underground whip and dense leaf has the advantages of rapid growth, lush foliage and easy collection. Several researches have reported the pharmacologic effects of the leave extracts from Sasa, a kind of common bamboo grass in Asia, including antitoxic, anti-inflammatory, anticancer and prevention of cardiovascular diseases (Shibata et al 1975(Shibata et al , 1976(Shibata et al , 1978(Shibata et al , 1979Tripathi et al 2006;Sakai et al 2008). However, few investigations have been carried out of other bamboo grass for their biological analysis and pharmacologic effects.…”

Changes of the antioxidant activity and active compounds content from two bamboo grass leaves, namely, Pleioblastus kongosanensis f. aureostriatus and Shibataea chinensis, as affected by different harvest season and drying methods were investigated and the main compounds that influence the antioxidant activity of two bamboo grasses were analyzed by principal component analysis. The content of total flavonoids, phenolics, triterpenoids and eight active compounds, i.e., orientin, isoorientin, vitexin, homovitexin and p‐coumaric acid, chlorogenic acid, caffeic acid, ferulic acid were determined by UV‐spectrophotometer and reverse phase high performance liquid chromatography synchronously, respectively, while antioxidant activity was measured using diphenyl‐2‐picryl‐ hydrazyl and ferric reducing antioxidant power methods. Both bamboo grasses leaves showed the highest level of total active components and antioxidant activity in winter. Different drying methods also affected the active compounds. Lyophilization, followed by vacuum drying and microwave oven drying, was the most suitable method for keeping active components, yet considering the energy consuming, microwave oven drying was recommended for bamboo grass leaves. Practical Applications Bamboo leaves, with excellent free radical scavenging, antioxidation, antibacterial, antiviral, enhancing immunity and other biological effectiveness, have been used for over 1,000 years in Asia as health food material and folk medicine. Bamboo grasses leaves, with advantages of rapid growth, lush foliage and easy collection, were a kind of new potential leafy bamboo grove. In order to improve the comprehensive utilization of leaves and exploit them more scientifically and efficiently, the present study investigated the changes of total phenolics, flavonoids, triterpenoid and eight active compounds content as well as antioxidant actives in leaves in accordance with seasonal variation and different drying methods. The results showed the optimum season for bamboo grass leaves harvest is at winter, and microwave oven drying was finally suggested for postharvest handling. It may provide a theoretical basis for further suitable exploitation and utilization of the leaf resources of the bamboo grasses.

“…Rehder (called Kumazasa in Japan) have been used for a long time in Asia as health food and in folk medicine, and recently, are used as a dietary and/or food supplement in Japan. It is reported that the leaves have various biological activities including antiulcer, 1,2 anti-inflammatory, 1 sedative, 2 detoxicating, 2 diuretic, 2 hypotensive, 3 anti-tumor, 4 -6 and antimicrobial 7 activities. However, scarcely any chemical investigation has been made on the plant.…”

“…6) Several pharmacological studies of Kuma-zasa have been conducted to verify these effects. [7][8][9] The botanical origins of Kuma-zasa were reported to be mainly S. palmata and S. senanensis, and rarely S. yahikoensis and S. kurilensis. 10,11) However, differences in pharmacological effects among species are unknown because it is difficult to identify the dried leaves of Sasa plants.…”

Kuma-zasa is Japanese folk medicine derived from plants of genus Sasa, family Bambusaceae. Although the plants of origin of Kuma-zasa were reported to be Sasa palmata, S. senanensis, S. yahikoensis, and S. kurilensis, authentication of those plants was difficult because of similarity in morphology. Several methods for the classification of genus Sasa are available, but none involve a genetic approach. Here, we performed the genetic profiling of genus Sasa, including the four species used medicinally. Thirteen sequences were observed in chloroplast DNA intron between rbcL and ORF106 and partial ORF106 regions of 34 specimens of 16 Sasa species and one specimen of Phyllostachys pubescens. We observed differences in alignment in this region among the specimens. The analyzed lengths varied from 759 to 821 bp depending on the specimen. There were nine base substitutions, eight successive thymines or adenines, and one to three repeat units of 31 bp. Moreover, we could not find species-specific alignment: different alignments were observed in specimens of the same species, while the same alignment was observed in specimens of different species. In the phylogenetic tree reconstructed by maximum parsimony analysis, medicinally used species did not form a cluster, although most of them were positioned close to each other. The genetic profiling of Sasa species would be of use in determining the botanical origin of the herbal medicine derived from the leaves of Sasa plants.
