Scutellarin (I) (yield 0.01 %), vicenin-2 (V) (yield 0.002 %), rosmarinic acid (VII) (yield 0.2%) and caffeic acid (VIII) (yield 0.005 %) were isolated and identified from the dried leaves of Perilla frutescens BRITTON var. acuta KUDO f. viridis MAKINO, a most popular garnish in Japanese cooking. Considering their yields, it was presumed that, of four above phenolics, rosmarinic acid plays a leading role in the harshness of this plant.
Perilla frutescens BRITTON var. acuta KUDO f. viridis MAKINO (Japanese name : Ao-jiso), annual herb of Labiatae, is well known as one of the most popular garnishes in Japanese cooking because of its excellent flavor. Some other features of this plant such as harsh taste and browning of leaf juice suggest the presence of phenolic constituents. However, so far the author is aware, they have not been examined chemically inspite of many papers concerning the origin of flavor. This paper deals with the isolation and identification of scutellarin, vicenin-2, rosmarinic acid and caffeic acid from its leaves.

To evaluate the extent of deterioration of thermally oxidized frying oils, the analyses by gel filtration on Sephadex LH-20 and Sephadex LH-60 were attempted.
The heated soybean oil (at 160°C for 0-67 hr) was separated into two fractions (polymerized and non-polymerized triglycerides) by Sephadex LH-20 chromatography. The polymerized products in the sample oil could not be fractionated into further components on LH-20 column. The monomer, dimer, trimer of triglycerides, and highly polymerized ones were obtained from the heated oil by gel filtration on Sephadex LH-60 according to their molecular sizes.
From the results, it was elucidated that the deterioration of thermally oxidized frying oils could be characterized in more detail by the application of Sephadex LH-20 and/or Sephadex LH-60 chromatographies together with the conventional chemical methods.

The changes in sugar, organic acid, vitamin C, and polyphenol contents in two species of raspberries, Rubus Sieboldi Blume. (I) and Rubus pareifolius Linn. (II) during ripening were studied.
Free sugars were found to be substantially consisted of fructose, glucose, and sucrose at every stage from unripe to ripe in each species. Their concentrations all tended to increase with development. Fructose and glucose predominated during ripening, while the ratio of reducing sugar to total soluble sugars decreased with maturity.
Organic acid concentration decreased simultaneously with the rise in sugar concentration. L-Dehydroascorbic acid concentration increased immediately as the berries progressed from the ripening stage 1, unripe state, to stage 2, during which the berries turned reddish. After that, it decreased in I with further ripening, while in II it continued to increase. L-Ascorbic acid concentration increased with maturity and at the ripe stage decreased significantly. In case of I, the ratio of L-ascorbic acid in reduced form to total ascorbic acid was remarkably low during ripening.
Both total polyphenol and associated tannin concentrations decreased markedly with development. And, during ripening, the major part of total polyphenol was found to be associated tannin.

Wearing a clothing assembly, we have a numerous space between skin and outermost layer of clothing. Its quantities means air volumes of the inter- and intra-clothing, which is an important factor to explain thermal properties, clothing functions and aethetical features.
This paper describes a new technique for estimating the clothing microclimate volumes. This method is based on the substitution water for the interclothing air, that is, an experimental clothing made of PVC film is hermetically sealed to exclude any external air with adhesive tapes and the interclothing air is exchanged for water, and then it is deaired with an air syringe.
According to this method, we can obtain sufficient accuracy within an error of ± 0.5 liters with the average value of three experiments, so this is a useful measurement of clothing microclimate volumes. If clothing design is the same, it can be considered that there is no effect of textile properties for one.

The author has already analyzed the patterns of emotional tie between elderly couples in the post-retirement stage. The purposes of this study are to find out in the same way whom adolescents and their parents want as the most important objects of egocentric-altruistic needs, to examine the patterns of emotional tie among them, and to compare those of couples in the different stages. The samples are university students (42 males, 52 females) and their parents.
The results are summarized as follows :
Many of the students want to have intimate relation to others rather than family members, but female students are more likely to rely on their parents than male students. On the other hand, most of their parents are not child-oriented but spouse-oriented. Emotional tie between couples in the post-retirement stage gets closer than that of couples in the pre-retirement stage.

This report tells how much energy is consumed for wiping with a damp cloth in housework. The experiment was done by two experimentalists using Douglas bag, in Feb. 1966. The author experimented to find the most efficient method by changing posture, working height and speed.
Three types of working postures, kneeling down, squatting down and standing pose using mop were tested. Rate of energy consumption shows standing pose to be the lowest, and squatting down consumes 30 % more energy than kneeling down. For working level 80 cm, above the floor, was the most efficient height. As for working speed, about 60 times/min and 120 times/ min were the most effective speed. The latter is appropriate for light wiping.
